  • PHP Game weapon accuracy

    - by noko
    I'm trying to come up with a way for players to fire their weapons and only hit for a certain percentage. For example, one gun can only hit 70% of the time while another only hits 34% of the time. So far all I could come up with is weighted arrays. Attempt 1: private function weighted_random(&$weight) { $weights = array(($weight/100), (100-$weight)/100); $r = mt_rand(1,1000); $offset = 0; foreach($weights as $k => $w) { $offset += $w*1000; if($r <= $offset) return $k; } } Attempt 2: private function weapon_fired(&$weight) { $hit = array(); for($i = 0; $i < $weight; $i++) $hit[] = true; for($i = $weight; $i < 100; $i++) $hit[] = false; shuffle($hit); return $hit[mt_rand(0,100)]; } It doesn't seem that the players are hitting the correct percentages but I'm not really sure why. Any ideas or suggestions? Is anything glaringly wrong with these? Thanks

  • My IF statement is changing variables in PHP

    - by user1902509
    I am fairly new to the whole programming thing, so forgive me if this is a stupid question. It seems odd that I haven't run into it before. I am trying to make an order form for a cake. You fill out the form, submit it, and it will then display the order in a new window, where you then hit "submit," and upload it to the Database. I have a series of If Statements to check for errors in the form before submitting it. Here is a simplified version of the code. Writing means any writing you want on the cake, Name is your name, and cake is what type of cake you want (the default is "None"). try { $name = trim($params->name); $cake = trim($params->cake); $writing = trim($params->writing); if (strlen($name) < 3){ throw new Exception("Please enter Your name."); } if ($cake = "None") { throw new Exception("Please select a Cake" } if ($cake = "Caramel Apple Pie" or $cake = "Pumpkin Pie" or $cake = "Eggnog Pie" and strlen($writing) > 1) { throw new Exception("We are sorry, but you can't write on any of our specialty pies."); } } catch(Exception $x) { $error = $x->getmessage(); } So what is happening is that when I go and hit submit the first time, the correct cake type comes up, but when you submit it the second time, the error comes up saying that I have "None" selected. All the other values are there and remain the same. I think the problem is that the first "IF" statement (Where it says "If($cake = "None")) is automatically changing $cake to "None" because I have tried commenting just that statement out, and it will then change the cake to be "Caramel Apple Pie," which is in the top of the next IF statement. Anyone know why it is doing this? And how to fix it?

  • PHP 5.3 and interface \ArrayAccess

    - by Jakub Lédl
    I'm now working on a project and I have one class that implements the ArrayAccess interface. Howewer, I'm getting an error that says that my implementation: must be compatible with that of ArrayAccess::offsetSet(). My implementation looks like this: public function offsetSet($offset, $value) { if (!is_string($offset)) { throw new \LogicException("..."); } $this->params[$offset] = $value; } So, to me it looks like my implementation is correct. Any idea what is wrong? Thanks very much! The class look like this: class HttpRequest implements \ArrayAccess { // tons of private variables, methods for working // with current http request etc. Really nothing that // could interfere with that interface. // ArrayAccess implementation public function offsetExists($offset) { return isset ($this->params[$offset]); } public function offsetGet($offset) { return isset ($this->params[$offset]) ? $this->params[$offset] : NULL; } public function offsetSet($offset, $value) { if (!is_string($offset)) { throw new \LogicException("You can only assing to params using specified key."); } $this->params[$offset] = $value; } public function offsetUnset($offset) { unset ($this->params[$offset]); } }

  • PHP: Which DB/DB Engine supports search well?

    - by KeyStroke
    Hi, I'm starting a site which relies heavily on search. While it's probably going to search basic meta data in the beginning, it might grow to something bigger in the future. So which DB/DB Engine is best in your opinion when it comes to search performance and future scalability? Appreciate your help

  • php - efficent way to get and remove first line in file

    - by Marco Demaio
    Hello, I have a script that each time is called gets the 1st line of a file. Each line is known to be exactly of the same length (32 alphanumerci chars) and terminates with a "\r\n". After getting the 1st line, the script removes it. Now I do in this way: $contents = file_get_contents($file)); $first_line = substr($contents, 0, 32); file_put_contents($file, substr($contents, 32 + 2)); //+2 because we remove also the \r\n Obvioulsy it works, but I was wondering if there could be a smarter (or more efficent) way to do this??? In my simple solution I basically read and rewrite all the file just to take and remove the 1st line. Thanks!

  • duplicate one element from php array

    - by robertdd
    how i can duplicate one element from array: for example, i have this array: Array ( [LRDEPN] => 0008.jpg [OABCFT] => 0030.jpg [SIFCFJ] => 0011.jpg [KEMOMD] => 0022.jpg [DHORLN] => 0026.jpg [AHFUFB] => 0029.jpg ) if i want to duplicate this: 0011.jpg , how to proceed? i want to get this: Array ( [LRDEPN] => 0008.jpg [OABCFT] => 0030.jpg [SIFCFJ] => 0011.jpg [NEWKEY] => 0011.jpg [KEMOMD] => 0022.jpg [DHORLN] => 0026.jpg [AHFUFB] => 0029.jpg )

  • PHP: Extract direct sub directory from path string

    - by Nebs
    I need to extract the name of the direct sub directory from a full path string. For example, say we have: $str = "dir1/dir2/dir3/dir4/filename.ext"; $dir = "dir1/dir2"; Then the name of the sub-directory in the $str path relative to $dir would be "dir3". Note that $dir never has '/' at the ends. So the function should be: $subdir = getsubdir($str,$dir); echo $subdir; // Outputs "dir3" If $dir="dir1" then the output would be "dir2". If $dir="dir1/dir2/dir3/dir4" then the output would be "" (empty). If $dir="" then the output would be "dir1". Etc.. Currently this is what I have, and it works (as far as I've tested it). I'm just wondering if there's a simpler way since I find I'm using a lot of string functions. Maybe there's some magic regexp to do this in one line? (I'm not too good with regexp unfortunately). function getsubdir($str,$dir) { // Remove the filename $str = dirname($str); // Remove the $dir if(!empty($dir)){ $str = str_replace($dir,"",$str); } // Remove the leading '/' if there is one $si = stripos($str,"/"); if($si == 0){ $str = substr($str,1); } // Remove everything after the subdir (if there is anything) $lastpart = strchr($str,"/"); $str = str_replace($lastpart,"",$str); return $str; } As you can see, it's a little hacky in order to handle some odd cases (no '/' in input, empty input, etc). I hope all that made sense. Any help/suggestions are welcome.

  • Converting a PHP array to class variables.

    - by animuson
    Simple question, how do I convert an associative array to variables in a class? I know there is casting to do an (object) $myarray or whatever it is, but that will create a new stdClass and doesn't help me much. Are there any easy one or two line methods to make each $key => $value pair in my array into a $key = $value variable for my class? I don't find it very logical to use a foreach loop for this, I'd be better off just converting it to a stdClass and storing that in a variable, wouldn't I? class MyClass { var $myvar; // I want variables like this, so they can be references as $this->myvar function __construct($myarray) { // a function to put my array into variables } }

  • If exist in array (php)

    - by Glister
    There are two arrays, that are given for $link from foreach. One time $link must be a first arrow, and a third - the second. So: 1 array: Array ( [width] => 800 [height] => 1142 [hwstring_small] => height='96' width='67' [file] => 2010/04/white-1051279.jpg [sizes] => Array ( [thumbnail] => Array ( [file] => white-1051279-100x150.jpg [width] => 100 [height] => 150 ) [medium] => Array ( [file] => white-1051279-200x285.jpg [width] => 200 [height] => 285 ) ) [image_meta] => Array ( [aperture] => 0 [credit] => [camera] => [caption] => [created_timestamp] => 0 [copyright] => [focal_length] => 0 [iso] => 0 [shutter_speed] => 0 [title] => ) ) 2 array: Array ( [width] => 50 [height] => 50 [hwstring_small] => height='50' width='50' [file] => 2010/04/images1.jpeg [image_meta] => Array ( [aperture] => 0 [credit] => [camera] => [caption] => [created_timestamp] => 0 [copyright] => [focal_length] => 0 [iso] => 0 [shutter_speed] => 0 [title] => ) ) The difference - first one has [sizes]. Searching for a way to detect, is there [sizes] in given array. Tryed if (in_array("[sizes]", $link)) { } else { }, but it doesnt work. Thanks.

  • how to hack this php class for parse ZIP file in random or specific order

    - by Jesse
    My English is poor so I will make it short. Right now, I have imzip.zip which has three txt files: a.txt b.txt c.txt When I try to load imzip.zip using: http://pastebin.com/m1d974990 It loads the files alphabetically. In this case: a.txt b.txt c.txt However, I would like to be able to have the class load on different variables such as by size, date or simply random. The problem is I have no idea how I would go about modifying the class to fit my needs. I would really appreciate your help! :D

  • How can I speed up a 1800-line PHP include? It's slowing my pageload down to 10sec/view

    - by somerandomguy
    I designed my code to put all important functions in a single PHP file that's now 1800 lines long. I call it in other PHP files--AJAX processors, for example--with a simple "require_once("codeBank.php")". I'm discovering that it takes about 10 seconds to load up all those functions, even though I have nothing more than a few global arrays and a bunch of other functions involved. The main AJAX processor code, for example, is taking 8 seconds just to do a simple syntax verification (whose operational function is stored in codeBank.php). When I comment out the require_once, my AJAX response time speeds up from 10sec to 40ms, so it's pretty clear that PHP's trying to do something with those 1800 lines of functions. That's even with APC installed, which is surprising. What should I do to get my code speed back to the sub-100ms level? Am I failing to get the cache's benefit somehow? Do I need to cut that single function bank file into different pieces? Are there other subtle things that I could be doing to screw up my response time? Or barring all that, what are some tools to dig further into which PHP operations are hitting speed bumps?

  • bcdiv() bcadd() bcsub() with Php

    - by Pieman
    Will this code be 'stressful' for a server? Or is it easy to bcdiv/sub/add to 10000 decimal places? I'm thinking of looping it afew times... Not Sure... $s2 = (bcdiv('1', $test, 10000)); $s = bcsub($s, $s2, 10000); $test += 2; $s3 = (bcdiv('1', $test, 10000)); $s = bcadd($s, $s3, 10000); $test += 2; Any advice? :)

  • PHP sleep() excution sequence while echoeing.

    - by Babiker
    I have the following: echo time()."<br>"; sleep(1); echo time()."<br>"; sleep(1); echo time()."<br>"; I wrote the preceding code with intention to echo time()."<br>" ln 1,echo time()."<br>" ln 4, wait a final second and then echo the final time()."<br>". Altough the time bieng echoed is correct when it comes to the intervals between time(), all echo functions are echoeing after the total of the waiting period/parameters in each sleep function. This is how the script runs: Excutes. Waits 2 secons. echoes 1275540664 1275540665 1275540666 Notice the correct incrementation in time() being echoed. My question is why is it not behaving like expected to where it echoes, waits a second, echoes again, waits one final second and then echos the last parameter? I know my question is a little confusing due to my wording, but i will try my hardest to answer any comments regarding this, thanks.

  • PHP Magento Screen Scraping

    - by Grant unwin
    I am trying to scrape a suppliers magento site in an effort to save some time because of there being around 2000 products I need to gather info for. I'm totally OK with writing a screen scraper for pretty much anything but i've encountered a major problem. Im using get_file_contentsto gather the html of the product page. The problem is: You need to be logged in, to view the product page. Its a standard magento login, so how can I get round this in my screen scraper? I don't require a full script, just advice on a method. Thanks

  • PHP ORM's, multiple tables and efficiency

    - by sunwukung
    Let's say I have a data mapper function that aggregates multiple tables and generates an object instance from that data. The mapper has a typical save() method which delegates to update/insert. When the mapper executes save - ideally it isolates object fields that have been modified, thus preventing the code from blanket bombing the database. How would you go about this?

  • Newbie - eclipse workflow (PHP development)

    - by engil
    Hi all - this is a bit of a newbie question but hoping I can get some guidance. I've been playing around with Eclipse for a couple months yet I'm still not completely comfortable with my setup and it seems like every time I install it to a new system I end up with different results. What I'm hoping to achieve is (I think) fairly standard. In my environment I'd like SVN (currently using Subclipse), FTP support (currently using Aptana plugin), debugging (going to use XDebug) and all the usual bells and whistles of development (code completion, refactoring, etc.) My biggest current issue is how to set up my environment to support both a 'development' and 'production' server. Optimally I would be able to work directly against the dev server (Eclipse on my Vista desktop against the VM Ubuntu dev server) and then push to production server (shared hosting). I'd prefer to work directly against the dev server (with no local project files, just using the Connections provided by Aptana) but I'm guessing this won't allow for code-completoin or all the other bells and whistles provided for development. Any thoughts? Kind of an open ended question, but maybe this could be an opportunity for some of you with a great deal of experience using Eclipse to describe your setups so people like me can get some insight into good ways to get set up.
