  • PHP - Using strcpsn() to protect against SQL injection?

    - by MichaelMitchell
    I am making a sort of form validation system and I need to check the SQL database to see if the username is already there. So, my question, is it effective to use a little if statement like this to protect against an attack? if (strcspn($string, "/\?!@#$%^&*()[]{}|:;<>,.\"\'-+=" == strlen($string)){ return true; } So essentially, if the string contains any of these characters, "/\?!@#$%^&*()[]{}|:;<>,.\"\'-+=", then the length will not equal that of the original $string. I am just wondering if this is sufficient to protect, or if there is more that I must do. Thanks.

  • [Using $this when not in object context in] php error

    - by JasonS
    I have solved this problem, I just need to know what to do. I get the above error because I just realised that the class is being run as class::function($values) instead of class-function($values). Does anyone know how to convert this function to instantiate the class then run the function with values? private function _load($values=null) { define('LOADED_CONTROLLER', $this->controller); define('LOADED_FUNCTION', $this->function); $function = $this->function; $controller = new $this->controller; ($values == null) ? $controller->$function() : call_user_func_array(array($this->controller, $function), $values); }

  • Implementing a Clock Drift random number generator in PHP

    - by Excl
    Hi, I wrote the following code: function create_rand($time) { $counter = 0; $stop = microtime(true) + $time; while(microtime(true) < $stop) $counter++; return $counter; } function create_rand_max($time, $a, $b = false) { $rand_a = create_rand($time); $rand_b = create_rand($time); $rand_c = create_rand($time); $max = max($rand_a, $rand_b, $rand_c); $min = min($rand_a, $rand_b, $rand_c); if($max === $min) return create_rand_max($time, $a, $b); $middle = $rand_a + $rand_b + $rand_c - $max - $min; if($b !== false) return min($a, $b) + ($middle - $min) * (max($a, $b) - min($a, $b)) / ($max - $min); return ($middle - $min) * $a / ($max - $min); } $stop = 1000; $sum = 0; for($i = 0; $i < $stop; $i++) { $sum += create_rand_max(0.001, 100, 200); } echo $sum / $stop; The average is usually between 157 to 161, instead of ~150. Any ideas?

    try { $con->beginTransaction(); $this->doSave($con); $con->commit(); } catch (Exception $e) { $con->rollBack(); throw $e; } The code above is quite standard an approach to deal with transactions, but my question is:what if $con->rollBack() also fails? It may cause db lock,right?If so,what's the perfect way to go?

  • PHP returns a negative number?

    - by Legend
    I am trying to query a bittorrent tracker and am using unpack to get the list of IPs from the response. So, something like this: $ip = unpack("N", $peers); $ip_add = ($ip[1]>>24) . "." . (($ip[1]&0x00FF0000)>>16) . "." . (($ip[1]&0x0000FF00)>>8) . "." . ($ip[1]&0x000000FF); But, for some reason, I am getting the following IP addresses when I print $ip_add: 117.254.136.66 121.219.20.250 -43.7.52.163 Does anyone know what could be going wrong?

  • Unique text field in MySQL and php

    - by Jonathan
    I've created a salt using; md5(rand(0,10000000)); (there is probably a better way?) There doesn't seem to be possible to make a text field unique in MYSQL. So how do I check if the salt has already been used for a previous user? Or should I generate the salt based on the current date/time? as it is impossible for 2 users to register at exactly the same time correct?

  • PHP: producing relative date/time from timestamps

    - by KeyStroke
    Hi, I'm basically trying to convert a Unix timestamp (the time() function) to a relative date/time that's both compatible with past and future date. So outputs could be: 2 weeks ago 1 hour and 60 minutes ago 15 minutes and 54 seconds ago after 10 minutes and 15 seconds First I tried to code this, but made a huge unmaintainable function, and then I searched the internet for a couple of hours, yet all I can find are scripts that produce only one part of the time (e.h: "1 hour ago" without the minutes). Do you have a script that already does this? If so, I'd really appreciate if you could share it. Thanks.

  • PHP: Three item validation comparison

    - by DavidYell
    I have 3 featured product panels on the homepage, and I'm writing a CMS page for it. I'm trying to validate the items. They are selected via three <select> elements, featured1, featured2 and featured3. The default is <option value="0" selected>Select an element</option> I need to validate the $_POST to ensure that the user hasn't selected the same product for more than one of the panels. I have worked out that each $_POST needs to be $_POST['featuredN'] > 0 but I can't seem to find a logical way of processing the 7 potential outcomes. Using a logic table, where 1 is a set value. 1 2 3 ------- 0 0 0 1 1 1 1 0 0 0 1 0 0 0 1 1 1 0 0 1 1 If an item is 0, then I will not update it, but I want the user to be able to update a single item if needs be. I cannot find a logical way to see if the item is not 0, and then compare it to another item if that also is not 0. So far my colleague suggested, adding up the values. Which works to see if condition 1 0 0 0 is not met. I have a vague feeling that some form of recursive function might be in order, but I can't quite get my brain to help me on this one! So to the collective brain! :)

  • sql select with php variable

    - by user1572526
    I'm trying to print out a html-table from db-table 'dimensions'. I only want dimensions from the selected pipetype which I get from a dropdownbox. For now I just put in "Steel" manually. Steel has pipe_id = 2 in db-table 'pipes'. I've run the first query in my db-tool and it returns 2 so there's nothing wrong there. The second query returns nothing. But when I manually set $wq = 2 (which I comment out below) it prints out the html-table perfectly. What am I doing wrong here? $wq="SELECT pipe_id FROM pipes WHERE title_en = 'Steel'"; //$wq = '2'; $sql="SELECT * FROM dimensions WHERE pipe_id = '".$wq."'";

  • effective counter for unique number of visits in PHP & MySQL

    - by Adnan
    Hello, I am creating a counter for unique number of visits on a post, so what I have until now is a table for storing data like this; cvp_post_id | cvp_ip | cvp_user_id In cases a registered user visits a post, for the first time a record is inserted with cpv_post_id and cvp_user_id, so for his next visit I query the table and if the record is available I do not count him as a new visitor. In cases of an anonymous user the same happens but now the cvp_ip and cpv_post_id are used. My concerns is that I do a query every time anyone visits a post for checking if there has been a visit, what would be a more effective way for doing this?

  • PHP: Doctrine: order joined records

    - by Sebastian Bechtel
    Hi, I'm new to doctrine: I have a problem with the sorting of joined records. A sample. I've got an Article model which is associated with a Source model in 1 <- n. The source model has a property called 'position' with an integer value. Now I want to fetch an article with it's sources orderes by the position. My DQL looks like this: $q = Doctrine_Query::create() ->select('a.title, s.content') ->from('Article a') ->leftJoin('a.Source s') ->where('a.id = ?') ->orderBy('s.position'); The result doesn't change if I edit the position. Best regards, Sebastian

  • getting bordering US states (php)

    HI need to be able to select a state and be given a list of the bordering states. Does anyone have or know of code already done for this? If I have to write it myself, what would be the best way - possibly a mysql database of borders (two state columns for each row), and then select matching?

  • PHP Extract Values From One String Based on a Pattern Defined in Another

    - by ironkeith
    I have two strings: $first = '/this/is/a/string'; $second = '/this/:param1/a/:param2'; And I'm trying to get this: $params = array('param1' => 'is', 'param2' => 'string'); But getting from point a to b is proving more than my tired brain can handle at the moment. Anything starting with a ':' in the second string defines a variable name/position. There can be any number of variables in $second which need to be extracted from $first. Segments are separated by a '/'. Thanks.

  • PNG composition using GD and PHP

    I am trying to take a rectangular png and add depth using GD by duplicating the background and moving it down 1 pixel and right 1 pixel. I am trying to preserve a transparent background as well. I am having a bunch of trouble with preserving the transparency. Any help would be greatly appreciated.

  • Slick PHP based image manager for managing user profile images

    - by franko75
    Hi, I'm just throwing this out there as I'm plodding my way through creating a Member Photo album on a site i'm working on, where they can login and upload their photos to a personal gallery. I want this to be nice and lightweight, but still slick and "modern" with a modal based interface for the user. I'm surprised though that there is seemingly nothing open source out there which fits the bill - I've done a few searches on Google to no avail and can't seem to find anything. Lots of bloated photo galleries out there but nothing looks like it has been developed using more recent technologies. Is anyone aware of anything which might suit what I'm looking for? I'm fully prepared to try and code it myself but I'd be delighted if I didn't have to! Pure laziness you might say, but there's no point reinventing the wheel.

  • Another php array looping question

    - by Dan
    Been battling with this one for what seems, like forever. I have an array: $url_array It contains this info: Array ( [ppp] => Array ( [0] => stdClass Object ( [id] => 46660 [entity_id] => 0 [redirect_url] => http://www.google.com [type] => Image ) [1] => stdClass Object ( [id] => 52662 [entity_id] => 0 [pixel_redirect_url] => http://www.yahoo.com [type] => Image ) [2] => stdClass Object ( [id] => 53877 [entity_id] => 0 [redirect_url] => http://www.msn.com [pixel_type] => Image ) ) [total_count] => 3 ) I need to loop through it, and do things to each variable. I can get this to work: foreach ($piggies_array as $key => $value) { $id = $value[0]->id; $redirect_url = $value[0]->redirect_url; } Not unsurprisingly, it's only echoing the first value of those variables, but no matter what I try I cannot get it to loop through: $value->redirect_url; $value=>redirect_url; I would appreciate any help.
