note 39136 added to function.file-exists

file_exists can decieve you sometimes. if you are building a path from a database, say an image path you may have some thing like this $filename="banners/".$arr[0]; where $arr[0] is the file name derived from the database now before displaying the image you want to make sure that it is in fact in the directory thus: if(file_exists($filename)) echo "<img src='$filename' border='0' />" Unfortunately this will display if $arr[0] is empty or null because "banners/" does in fact exist! therefore it is better to use is_file if(is_file($filename)) echo "<img src='$filename' border='0' />" ---- Manual Page -- http://www.php.net/manual/en/function.file-exists.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+39136 Delete -- http://master.php.net/manage/user-notes.php?action=delete+39136&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+39136&report=yes Search -- http://master.php.net/manage/user-notes.php
