For some reason this PHP code below will not work, I can not figure it out.
It is very strange, file_exists does not seem to see that the image does exist, I have checked to make sure a good file path is being inserted into the file_exists function and it is still acting up
If I change file_exists to !file_exists it will return an images that exist and ones that do not exist
define('SITE_PATH2', 'http://localhost/'); $noimg = SITE_PATH2. 'images/userphoto/noimagesmall.jpg'; $thumb_name = 'http://localhost/images/userphoto/1/2/2/59874a886a0356abc1_thumb9.jpg'; if (file_exists($thumb_name)) { $img_name = $thumb_name; }else{ $img_name = $noimg; } echo $img_name;

The file_exists() function checks whether a file or directory exists.
The file_exists() function in PHP is an inbuilt function which is used to check whether a file or directory exists or not. The path of the file or directory you want to check is passed as a parameter to the file_exists() function which returns True on success and False on failure.
PHP Create File - fopen() The fopen() function is also used to create a file. Maybe a little confusing, but in PHP, a file is created using the same function used to open files. If you use fopen() on a file that does not exist, it will create it, given that the file is opened for writing (w) or appending (a).
To check if a file exists, you pass the file path to the exists() function from the os. path standard library. If the file exists, the exists() function returns True . Otherwise, it returns False .
file_exists() needs to use a file path on the hard drive, not a URL. So you should have something more like:
$thumb_name = $_SERVER['DOCUMENT_ROOT'] . 'images/userphoto/1/2/2/59874a886a0356abc1_thumb9.jpg'; if(file_exists($thumb_name)) { some_code } http://us2.php.net/file_exists
