  • Super strange PHP error

    - by Industrial
    Hi everyone, When trying memcache:get, I'll get the following error message back: Message: Memcache::get() [memcache.get]: Server localhost (tcp 11211) failed with: Failed reading line from stream (0) I run a Windows 32bit test environment (XP) and here's how my code looks: function getMulti(array $keys) { $items = $this->memcache->get($keys); return $items; } My memcache servers are two local computers in the LAN that my dev. environment is connected to. Sure, I can turn the error logging off or just put an @ before the get function call, but that doesnt solve this issue. What can I do? Thanks a lot!

  • PHP variable question

    - by Kyle Parisi
    This works: $customerBox = mysql_query("MY SQL STATEMENT HERE"); $boxRow = mysql_fetch_array($customerBox); $customerBox = mysql_query("MY SQL STATEMENT AGAIN"); while($item = mysql_fetch_assoc($customerBox)) { foreach ($item as $columnName = $value) { if (empty($value)) { print $columnName; } } } This does not: $customerBox = mysql_query("MY SQL STATEMENT HERE"); $boxRow = mysql_fetch_array($customerBox); while($item = mysql_fetch_assoc($customerBox)) { foreach ($item as $columnName = $value) { if (empty($value)) { print $columnName; } } } Why? I guess I don't understand how variables work yet.

  • PHP : flatten array - fastest way?

    - by Industrial
    Is there any fast way to flatten an array and select subkeys ('key'&'value' in this case) without running a foreach loop, or is the foreach always the fastest way? Array ( [0] => Array ( [key] => string [value] => a simple string [cas] => 0 ) [1] => Array ( [key] => int [value] => 99 [cas] => 0 ) [2] => Array ( [key] => array [value] => Array ( [0] => 11 [1] => 12 ) [cas] => 0 ) ) To: Array ( [int] => 99 [string] => a simple string [array] => Array ( [0] => 11 [1] => 12 ) )

  • Problem with php GD image not creating

    - by ThinkingInBits
    With the following code, my browser is returning 'image not created or saved'. I assure you the location of the image exists. So the line within the if statement is returning false for some reason, and yes GD is installed. Any ideas? if ($img = @imagecreatefromjpeg("/var/www/images/upload/1/1.jpg")) { $image_width = imagesx($img); $image_height = imagesy($img); $target_width = 150; $target_height = 150; if ($image_width > $image_height) { $percentage = ($target_width / $image_width); } else { $percentage = ($target_height / $image_height); } $new_image_width = round($image_width * $percentage); $new_image_height = round($image_height * $percentage); $imgResized = imagecreatetruecolor($new_image_width, $new_image_height); imagecopyresampled($imgResized, $img, 0, 0, 0, 0, $new_image_width, $new_image_height, $image_width, $image_height); imagejpeg($imgResized, $this->path, 100); imagedestroy($img); imagedestroy($imgResized); $this->storeThumbnailLocation(); } else { die ("image was not created or saved"); }

  • PHP Detect Pages Genre/Category

    - by Alexwhin
    Hey, I was wondering if their was any sort of way to detect a pages genre/category. Possibly their is a way to find keywords or something? Unfortunately I don't have any idea so far, so I don't have any code to show you. But if anybody has any ideas at all, let me know. Thanks! EDIT @Nican Perhaps their is a way to set, let's say 10 category's (Entertainment, Funny, Tech). Then creating keywords for these category's (Funny = Laughter, Funny, Joke etc). Then searching through a webpage (maybe using a cUrl) for these keywords and assigning it to the right category. Hope that makes sense.

  • php:: apply backticks to first word in sentence

    - by Hailwood
    Hi guys, basically what I am trying to do is, I have an array that looks something like this: array( array( 'select' =>'first string', 'escape' => true ), array( 'select' =>'second', 'escape' => true ), array( 'select' =>'the third string', 'escape' => true ), array( 'select' =>'fourth string', 'escape' => false ), ) I am looping over it and I want to end up with this output array( array( 'select' =>'`first` string', 'escape' => true ), array( 'select' =>'`second`', 'escape' => true ), array( 'select' =>'`the` third string', 'escape' => true ), array( 'select' =>'fourth string', 'escape' => false ), ) so basic rules are backticks are only applied if escape is true backticks are only applied to the first word in a sentence if there is only one word backticks are applied to the word My plan was to use if($item['escape']) { $pos = (strpos($item['select'], ' ') === false ? strlen($item['select']) : strpos($item['select'], ' ')); $item['select'] = '`' . substr($item['select'], 0, $pos) . '`' . substr($item['select'], $pos, strlen($item['select'])); } but the $item['select'] = line seems rather long winded, is there a better way to write it?

  • How to assign variable dynamically to php list function

    - by ravisoni
    What I am doing that I want to generate a list based on how many items are in an array, so I have counted the items and loop over them, create a number based var and construct a string $var which contains $a1,$a2.... and assigns the $var to list list($var) and tried to access $a1 but it gives me the error "Undefined variable: a1" Is there any other way to do it? Here is my code: $arr = array('1','2','3'); $listsize = count($arr); $var=''; for($i=1;$i<=$listsize;$i++){ $var.='$a'.$i; if($i!=$listsize){ $var.=','; } } list($var) = $arr; echo $a1;

  • PHP string enocding issue - Extra characters appearing

    - by ryan
    I see extra characters like â showing because of encoding issues as I found out here - HTML encoding issues - "Â" character showing up instead of "&nbsp;" I understand that if I set the browser meta encoding to UTF-8, these will not affect anything but I need to strip these extra characters from the database for other purposes. For eg. : Text: ↑ should be become Text: ? But if I run it through utf8_decode it gives me Text: ??? For every other occurrence of the â character, it converts properly to a blank space. Any help will be appreciated.

  • php adding value to session

    - by antikbd
    I am trying to implement a 'shopping cart' where, if the 'Add to Cart' has been clicked, the respective item is either added to the cart or incremented by one if already present. However, the following code isn't working and giving me a "Cannot use a scalar value as an array" error. Any help would be highly appreciated. if (isset($_POST['fan']) && ($_POST['fan']=="Add to Cart")) { if (($_SESSION['cart']['fan']==0) || (!isset($_SESSION['cart']['fan']))) { $_SESSION['cart']['fan']=1; } else { $_SESSION['cart']['fan']++; } }

  • PHP 1-liner each() with mysql_fetch_assoc()

    - by MVC You Know Me
    Hey All. Trying to create a 1-liner to loop through a mysql result set. Example: $sql = "SELECT uid, role FROM usr WHERE uid = '$this-uid'"; $r = db::q($sql); if($r-rows()) { $q = mysql_fetch_assoc($r-result); while(list($k, $v) = each($q)) { // would like to omit line above and consolidate here $_SESSION['usr'][$k] = $this->$k = $v; } } problem is that consolidating while loop like so: while(list($k, $v) = each(mysql_fetch_assoc($r-result)) returns an error a la each() not getting object or array, even though of course it is. I think the problem is a casting issue, but it does not seem you can do: each( (array) mysql_fetch_assoc($r-result)) Any ideas? I like to code as tersely as possible, and having "$q = mysql_fetch_assoc($r-result)" everywhere will annoy me, does already. Keep posted... Thanks!

  • PHP function: find argument's variable name, and function calls line number

    - by Majid
    I want to do something like this for simplifying logging operations. Any idea what I should put in for ?[1]? and ?[2]?? function log_var($var) { $line = ?[1]?; $var_name = ?[2]?; $line--; $filepath = 'log-' . date('Y-m-d'). '.txt'; $message = "$line, $var_name = $var\n"; $fp = fopen($filepath, "a"); fwrite($fp, $message); fclose($fp); @chmod($filepath, 0666); return TRUE; } This how I'd use the function in code (numbers are assumed to be line numbers in actual code): 23 $a = 'hello'; 24 log_var($a); 25 $b = 'bye'; 26 log_var($b); And this is what I want to be written to the log file: 23, a = hello 25, b = bye
