Fix disabled readfile function in PHP
Recently i had a problem with my blog. Actually the problem was on the server sever side where my blog hosted. I use a theme that require or use timthumb plugin. Maybe you already knew, i used it to generate and display thumbnail image, pretty good. The problem is the timthumb plugin use readfile function to read the image file and i dont know for sure why, my hosting service administrator just listed it as a disabled PHP function.
I do the ritual, search for a solution, and the only alternative i found is to change the the readfile function. There are some function alternative i think, combination between fopen and fpassthru worked on some server (it works on my private/offline server) but file_get_contents function works best.
this is the example code, (timthumb.php)
$fileSize = filesize( $cache_file ); header( "Content-Type: " . $mime_type ); header( "Accept-Ranges: bytes" ); header( "Last-Modified: " . gmdate( 'D, d M Y H:i:s', filemtime( $cache_file ) ) . " GMT" ); header( "Content-Length: " . $fileSize ); header( "Cache-Control: max-age=9999, must-revalidate" ); header( "Etag: " . md5($fileSize . $gmdate_mod) ); header( "Expires: " . gmdate( "D, d M Y H:i:s", time() + 9999 ) . "GMT" ); readfile( $cache_file ); exit;
i replace the readfile function and become
$fileSize = filesize( $cache_file ); header( "Content-Type: " . $mime_type ); header( "Accept-Ranges: bytes" ); header( "Last-Modified: " . gmdate( 'D, d M Y H:i:s', filemtime( $cache_file ) ) . " GMT" ); header( "Content-Length: " . $fileSize ); header( "Cache-Control: max-age=9999, must-revalidate" ); header( "Etag: " . md5($fileSize . $gmdate_mod) ); header( "Expires: " . gmdate( "D, d M Y H:i:s", time() + 9999 ) . "GMT" ); $img_data = file_get_contents( $cache_file ); echo $img_data; exit;
i hope this helps.
I use that file_get_contents function all the time, it save me a lot of time
