note 60241 added to function.imagecreatefromjpeg

In addition to yaroukh at gmail dot com comment. It seems that even a small image can eat up your default memory limit real quick. Config value 'memory_limit' is marked PHP_INI_ALL, so you can change it dynamically using ini_set. Therefore, we can "allocate memory dynamically", to prevent those memory limit exceeded errors. <?php $imageInfo = getimagesize('PATH/TO/YOUR/IMAGE'); $memoryNeeded = round(($imageInfo[0] * $imageInfo[1] * $imageInfo['bits'] * $imageInfo['channels'] / 8 + Pow(2, 16)) * 1.65); if (function_exists('memory_get_usage') && memory_get_usage() + $memoryNeeded > (integer) ini_get('memory_limit') * pow(1024, 2)) { ini_set('memory_limit', (integer) ini_get('memory_limit') + ceil(((memory_get_usage() + $memoryNeeded) - (integer) ini_get('memory_limit') * pow(1024, 2)) / pow(1024, 2)) . 'M'); } ?> ---- Manual Page -- http://www.php.net/manual/en/function.imagecreatefromjpeg.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+60241 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+60241&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+60241&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+60241&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+60241&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+60241&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+60241&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+60241&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+60241&report=yes Search -- http://master.php.net/manage/user-notes.php
