#21676 [Com]: GetImageSize nolonger works

ID: 21676 Comment by: spamthis@newcity.com Reported By: moderator@blackpeeps.com Status: No Feedback Bug Type: GetImageSize related Operating System: RAQ4-Latest Patches/Apache 1.3.2 PHP Version: 4.3.0 New Comment: Yesterday I wrote a script that scans a remote server for image files and then uses getimagesize to determine if its jpeg or png in order to create thumbnails. When I wrote it, I was using 4.23 . Everything worked beautifully. Every image reported correctly and created a thumbnail. Then I used getimagesize again to create width and height attributes in html img tags to make the full size pictures fit on screen. Still everything was working like a 12 year old in a Nike factory... Then I commented to my SysAdmin that I would love to have mb functions enabled for japanese support and how 4.3 has this enabled by default, so he installed 4.3 . Now getimagesize is f$%ked up. Some images still report remotely just fine, but the vast majority do not. I decided to see if this was a connectivity issue by using fopen()...I figured if the pointer returned, then the script can find the image. I get consistent connections with fopen, so I KNOW this is a problem with getimagesize() . I know modifications were made to getimagesize as of 4.3 regarding Mime Types, etc. I think when those modifications were made, old code broke. To test for yourself, set up something like this: $path = "http://youdomain/dir/"; $arrImg = array("xxx.jpg", "xxx2.jpg" ... "xxx20.jpg"); # Test with a lot of different jpgs ~20+ for($i = 0, $m = count($arrImg); $i<$m; $i++) { $size = getimagesize($path . $arrImg[$i]); if ( is_array($size) ) { echo "$arrImg[$i]: $size[0] x $size[1] \n\n"; } else { echo "$arrImg[$i]: getimagesize failed \n"; if ( !$fp = fopen($path . $arrImg[$i], "r") ) { echo "fopen also failed \n"; } else { fclose($fp); echo "fopen found the file\n\n"; } } } die; Previous Comments: ------------------------------------------------------------------------ [2003-02-13 09:07:44] webmaster@no_for_spam.radio.cz I can only confirm the former posts: PHP 4.3.0, Apache 1.3.27 on Linux gets confused on some pictures - getimagesize doesn't return correct width / height (it returns FALSE, in fact). Some 60% of all my images are not processed correctly (all of them worked with PHP 4.2.3). An example of such an image is: http://img.radio.cz/pictures/doprava/autobazar1x.jpg If I call getimagesize("http://img.radio.cz/pictures/doprava/autobazar1x.jpg") it returns FALSE, however in case of getimagesize("/the_real_path/pictures/doprava/autobazar1x.jpg") all works fine. Sorry, I can't test the CVS version right now. ------------------------------------------------------------------------ [2003-01-31 13:52:04] sniper@php.net No feedback was provided.
