is_file

Tells whether the filename is a regular file

Syntax

is_file ( string $filename ) : bool

Parameters

filename

Path to the file.

Return

Returns TRUE if the filename exists and is a regular file, FALSE otherwise.

Note: Because PHP's integer type is signed and many platforms use 32bit integers, some filesystem functions may return unexpected results for files which are larger than 2GB.

Examples

1

<?

$filename = $_SERVER["DOCUMENT_ROOT"] . "/assets/txt/file.txt";

$return = is_file($filename);

var_export($return);

?>
true

2

<?

$filename = "false.txt";

$return = is_file($filename);

var_export($return);

?>
false
