For my image gallery script I need to know if the GD version is 1.x or >=2 because I want to use TrueColor-capable functions if available, otherwise have the script fall back to the HiColor versions. To that end, I wrote a function that grabs just the major version number of the installed GD extension. This function works on versions of PHP older than 4.3. /** * Get which version of GD is installed, if any. * * Returns the version (1 or 2) of the GD extension. */ function gdVersion() { if (! extension_loaded('gd')) { return; } ob_start(); phpinfo(8); $info=ob_get_contents(); ob_end_clean(); $info=stristr($info, 'gd version'); preg_match('/\d/', $info, $gd); return $gd[0]; } // end function gdVersion() // The function is easy to use. if ($gdv = gdVersion()) { if ($gdv >=2) { echo 'imageCreateTruecolor() and imageCopyResampled() functions may be used.'; } else { echo 'imageCreate() and imageCopyResized() functions must be used.'; } } else { echo "The GD extension isn't loaded."; } ---- Manual Page -- http://www.php.net/manual/en/function.gd-info.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+40517 Delete -- http://master.php.net/manage/user-notes.php?action=delete+40517&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+40517&report=yes Search -- http://master.php.net/manage/user-notes.php
