  • PHP calling and displaying CSS in different browser.

    - by user147685
    I'm having problem with CSS where, when I run on Mozilla Firefox the CSS is doing fine. But when I run inside Internet Explorer, the CSS is not working. When I try to change the code in the CSS file, it works otherwise. Mozilla is OK, but Internet Explorer is not. I have an idea calling 2 different CSS. For example, style_IE.css and style_moz.css. Both CSS files will be called from header.html. How can I fix this problem? Is there some code that can distinguish between browsers? Whenever the user is running in Internet Explorer, then style_IE is called if not it otherwise.

  • A PHP script to stream internet radio?

    - by Honus Wagner
    I've been searching and searching and I haven't yet come up with a solution to host my own streaming audio player. I'm looking for a way to host an internet radio player that connects to whatever streams I enter in and plays them. I'm not looking to play my MP3s or anything like that. I'm looking to play content from 181.fm or 1Club.fm, for example. I'd even settle for ShoutCast-only streams. I've been to www.wavestreaming.com but it didnt work for me. I'm guessing its because in the very first box where you enter your website url, it leads in for you: http//www. then you fill in the rest. My site is https:// and does not contain a www. in the URL. I'm guessing that has something to do with it. Any links, suggestions for search topics, or even a brief technical overview of what I should be looking into would be greatly appreciated. Thanks for your time.

  • Array Unique in two dimentional array in PHP

    - by Kaiser
    Hi I have an array that looks like this : Array ( [0] => Array ( [x] => 01 [y] => 244 ) [1] => Array ( [x] => 02 [y] => 244 ) [2] => Array ( [x] => 03 [y] => 244 ) [3] => Array ( [x] => 04 [y] => 243 ) [4] => Array ( [x] => 05 [y] => 243 ) [5] => Array ( [x] => 05 [y] => 244 ) [6] => Array ( [x] => 06 [y] => 242 ) [7] => Array ( [x] => 06 [y] => 243 ) [8] => Array ( [x] => 07 [y] => 243 ) [9] => Array ( [x] => 08 [y] => 243 ) [10] => Array ( [x] => 09 [y] => 242 ) [11] => Array ( [x] => 10 [y] => 244 ) [12] => Array ( [x] => 12 [y] => 243 ) [13] => Array ( [x] => 13 [y] => 243 ) [14] => Array ( [x] => 13 [y] => 243 ) [15] => Array ( [x] => 15 [y] => 243 ) ) x represent days and y values of a certain variable.

  • PHP bitwise left shifting 32 spaces problem and bad results with large numbers arithmetic operations

    - by Victor Stanciu
    Hello, I have the following problems: First: I am trying to do a 32-spaces bitwise left shift on a large number, and for some reason the number is always returned as-is. For example: echo(516103988<<32); // echoes 516103988 Because shifting the bits to the left one space is the equivalent of multiplying by 2, i tried multiplying the number by 2^32, and it works, it returns 2216649749795176448. Second: I have to add 9379 to the number from the above point: printf('%0.0f', 2216649749795176448 + 9379); // prints 2216649749795185920 Should print: 2216649749795185827

  • PHP: How to dynamically add to http_build_query?

    - by oni-kun
    I have a scraping object basically. I want to be able to add POST variables to it like $obj->addvar('Name', 'Value'); What I have now is this: function addvar($var, $val) { $postvars[] = Array($var=>$val); } function initiate() { $this->q = $postvars; } if(!empty($this->post)) { $this->params = http_build_query($q); } I haven't tested because it's too incomplete, But would my addvar() function work? How on earth do I append a key+value to the array so http_build_query would accept it? IE (this is what I want): $obj->addvar('username', 'abc'); $obj->addvar('password', 'foobar'); $obj->send(); //..

  • PHP: why is this null different from the other null

    - by matthy
    hi i tried 2 things what should be the same however it my testing says different does anyone know why the only thing i do is put it in a variable... if ($_SESSION[$something] === null) echo("this is null"); $_SESSION[$something] does not exists so it indeed says: "this is null". now look at this $theSession = $_SESSION[$something]; if (theSession === null) echo("this is null"); now it does not say "this is null" while it should be exactly the same right?

  • PHP's PDO Prepare Method Fails While in a Loop

    - by Andrew G. Johnson
    Given the following code: // Connect to MySQL up here $example_query = $database->prepare('SELECT * FROM table2'); if ($example_query === false) die('prepare failed'); $query = $database->prepare('SELECT * FROM table1'); $query->execute(); while ($results = $query->fetch()) { $example_query = $database->prepare('SELECT * FROM table2'); if ($example_query === false) die('prepare failed'); //it will die here } I obviously attempt to prepare statements to SELET everything from table2 twice. The second one (the one in the WHILE loop) always fails and causes an error. This is only on my production server, developing locally I have no issues so it must be some kind of setting somewhere. My immediate thought is that MySQL has some kind of max_connections setting that is set to 1 and a connection is kept open until the WHILE loop is completed so when I try to prepare a new query it says "nope too many connected already" and shits out. Any ideas? EDIT: Yes I know there's no need to do it twice, in my actual code it only gets prepared in the WHILE loop, but like I said that fails on my production server so after some testing I discovered that a simple SELECT * query fails in the WHILE loop but not out of it. The example code I gave is obviously very watered down to just illustrate the issue.

  • Mark duplicates in MySql with php (without deleting)

    - by Adam
    So, I'm having some problems with a MySQL query (see other question), and decided to try a different approach. I have a database table with some duplicate rows, which I actually might need for future reference, so I don't want to remove. What I'm looking for is a way to display the data without those duplicates, but without removing them. I can't use a simple select query (as described in the other question). So what I need to do is write a code that does the following: 1. Go through my db Table. 2. Spot duplicates in the "ip" column. 3. Mark the first instance of each duplicate with "0" (in a column named "duplicate") and the rest with "1". This way I can later SELECT only the rows WHERE duplicate=0. NOTE: If your solution is related to the SELECT query, please read this other question first - there's a reason I'm not just using GROUP BY / DISTINCT. Thanks in advance.

  • Help with PHP recursive navigation list menu

    - by Jason
    Hi all, I am trying to add a dynamic recursive navigation list menu to a site of am working on. The scenerio is that the menu has 2 levels related by a parentid(preid). My issue is that I can display the 1st level list correctly, however I cannot get the second level to display properly. I am not sure where to add the UL and /UL tags for the second level. This is what I am after <ul> <li>Item 1</li> <li>item 2</li> <li>item 3</li> <ul> <li>sub item 1</li> <li>sub item 2</li> </ul> <li>Item 4</li> <li>item 5</li> <ul> <li>sub item 1</li> <li>sub item 2</li> </ul> <li>item 6</li> </ul> This is actually what i am getting with the below code: <ul> <li>item 1 <ul> </ul> </li> <li>item 2 <ul> <li>sub item 1</li> <ul> </ul> <li>sub item 2</li> <ul> </ul> </ul> </li> <li>Sports Injuries <ul> </ul> </li> </ul> </li> </ul> Below is the class file I am using to create the menu: class Dynamic_Menu { function getConfig() { $this->DB_SERVER = 'localhost'; $this->DB_USER = '***'; $this->DB_PASS = '***'; $this->DB_NAME = '***'; } function __construct() { $this->getConfig(); $Conn = mysql_connect($this->DB_SERVER, $this->DB_USER, $this->DB_PASS); if (!$Conn) die("Error: ".mysql_errno($Conn).":- ".mysql_error($Conn)); $DB_select = mysql_select_db($this->DB_NAME, $Conn); if (!$DB_select) die("Error: ".mysql_errno($Conn).":- ".mysql_error($Conn)); } function select_row($sql) { //echo $sql .

I have been banging my head with this for the last 2 days. Any help would be greatly appreciated, thanks...

  • My PNG has transparency, but after saving with PHP GD, transparency is lost [closed]

    - by Harry Stroker
    I found the solution to my problem. See below the original post and completely at the bottom my solution. I made a stupid mistake :) First I crop an image and then save it to a png file. Right after this, I also show the image. However, the saved png does not have transparency and the shown one has. What is going on? $this->resource = imagecreatefrompng($this->url); imagealphablending($this->resource, false); imagesavealpha($this->resource, true); $newResource = imagecreatetruecolor($destWidth, $destHeight); imagealphablending($newResource, false); imagesavealpha($newResource, true); $resample = imagecopyresampled($newResource,$this->resource,0,0,$srcX1,$srcY1,$destWidth,$destHeight,$srcX2-$srcX1, $srcY2-$srcY1); imagedestroy($this->resource); $this->resource = $newResource; // SAVING imagepng($this->resource, $destination, 100); // SHOWING header('Content-type: image/png'); imagepng($this->resource); The reason I also save the image is for caching. If the script is executed on a png, it saves a cached png. Next time the image is requested, the png file will be shown, but it has lost its transparency. Even stranger: When I save that cached png image as (within Firefox), it saves it suddenly as a jpg, even though the extension was png. Downloading the cached png using chrome and opening it in Photoshop gives the error: "file-format module cannot parse the file". I will show you the shown PNG and the generated PNG: http://www.foodmuseum.nl/SaveProblemTransparency.png Once I try to show that saved PNG with the GD library, it gives me an error. EDIT NO NO NO NO THIS IS NOT A DUPLICATE!!!... I ALREADY USED THEIR SOLUTION. The solution in the supposedly duplicate works for showing my image. But I also try to save it with the exact same resource, but then it has no transparency. EDIT 2 - SOLUTION I found out what the problem was. It was a stupid mistake. The script I provided above were cut out of a class and placed as sequential code, while in real this is not what exactly happened. The save image function: function saveImage($destination,$quality = 90) { $this->loadResource(); switch($extension){ default: case 'JPG': case 'jpg': imagejpeg($this->resource, $destination, $quality); break; case 'gif': imagegif($this->resource, $destination); break; case 'png': imagepng($this->resource, $destination); break; case 'gd2': imagegd2($this->resource, $destination); break; } } However... $extension does not exist. I fixed it by adding: $extension = $this->getExtension($destination);

  • PHP Site Deployment Suggestion

    - by TheOnly92
    I'm currently quite troubled by the way of deployment my team is adopting... It's very old-fashioned and I know it doesn't work very well. But I don't exactly know how to change it, so please give some suggestions about it... Here is our current setup: 2 webservers 1 database server 1 test server Current deployment adaptation 1. We develop and work on the test server, every changes is uploaded manually to the test server. 2. When a change or feature is complete, we then commit the changes to SVN repository. 3. After committing the changes, we then upload our changes to the first webserver, where there will be a cronjob running every minute to sync the files between the servers. Something very annoying is, whenever we upload a file just as the syncing job starts, the file that is sync-ed will appear corrupted, since it is only half-uploaded. Another thing is whenever there is a deployment fault, it will be extremely difficult to revert. These are basically the problem I'm facing, what should I do?

  • PHP SimpleXML - Remove xpath node

    - by Peter John
    Hi, I'm a little confused as to how i can delete a parent node of something which i can find via an xpath search: $xml = simplexml_load_file($filename); $data = $xml->xpath('//items/info[item_id="' . $item_id . '"]'); $parent = $data[0]->xpath("parent::*"); unset($parent); So, it finds the item id, no problems there - but the unset isnt getting rid of this <items> node. All i want to do is remove the <items>...</items> for this product. Obviously, there are loads of <items> nodes in the xml file so it cant do unset($xml->data->items) as that would delete everything. Any ideas much appreciated :-)
