file_exists

(PHP 3, PHP 4 )

file_exists -- Checks whether a file or directory exists

Description

bool file_exists ( string filename)

Returns TRUE if the file or directory specified by filename exists; FALSE otherwise.

On windows, use //computername/share/filename or \\computername\share\filename to check files on network shares.

Example 1. Testing whether a file exists

<?php
$filename = '/path/to/foo.txt';

if (file_exists($filename)) {
    print "The file $filename exists";
} else {
    print "The file $filename does not exist";
}
?>

Note: The results of this function are cached. See clearstatcache() for more details.

Note: This function will not work on remote files as the file to be examined must be accessible via the servers filesystem.

See also is_readable(), is_writable(), is_file() and file().
