  php ajax
  I am calling for a function inside of a class on my website. It works on the majority of pages from what I’ve noticed, however when it tries to do the same thing on AJAX pages (pages that are only accessed through AJAX requests), it seems to error.function formatUsername($id,$link = true,$styles = true, $class = ”){global $users;return $users->formatUsername($id,$link,$styles,$class); }is where it is erroring (the return $users->) bit. (global.php)The actual formatUsername code is: (class.us

  I’ve searched a lot of basically the same questions on SO which haven’t seemed to help. Been a while since i’ve touched php so i’m guessing there’s a simple solution but really can’t figure it out.config.php: (included into admin.php)$mysqli = new mysqli($mHost, $mUser, $mPass, $db);admin.php:$sqlQuery = “INSERT INTO `category` (`id`, `name`) VALUES (”, ‘$_POST[name]’)”; $result = $mysqli->query($sqlQuery);var_dump($result) returns: NULLand gives error: Fatal error: Call to a member function qu

  php simplexml
  I am experiencing a very odd error. I am writing a function to validate XML based on element names, in this case passed in as an array. First, I normalize the input to a SimpleXMLElement object; in this case I am passing in a DOMDocument, and I tested it, it is converting correctly to SimpleXMLElement.What confuses me is that calling getName() will throw the following:PHP Fatal error: Call to a member function getName() on a non-objectBut using exit($xml->getName()) (or echo) will return the

  php html
  Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 13965430 bytes)PHPInfo shows that I have a memory_limit of 128M, so I’m confused as to why the error says I only have 64M… Is it possible for phpinfo to report incorrectly? Or for PHP to use two separate php.inis?[UPDATE] The error was being caused by an ini_set call in one of the primary php files that a co-worker of mine added without my knowledge. Thanks for your help guys.

  php pdo prepared-statement
  I was getting this Fatal error at the bottom of the page and didn’t see it right away. The error was pointing to a variable, the $sql, an SQL string, which is supposed to be an SQL string. The code was “$s = $pdo->prepare($sql);”. It seemed to work right, accessing the database and retrieving the correct information. I had used this code before earlier on another page creating a new PDO connection. Finally, after reading one of the comments on this error which I can’t find again, I decid
