unlink

Deletes a file

Syntax

unlink(string $filename, resource $context = ?): bool

Parameters

If the file is a symlink, the symlink will be deleted. On Windows, to delete a symlink to a directory, rmdir() has to be used instead.

context

A context stream resource.

Return

Returns true on success or false on failure.

$filename = 'unlink.txt';

$handle = fopen($filename, $mode);

    $string = 'unlink';

$return = unlink($filename);

echo $return;

?>
