ftell

Returns the current position of the file read/write pointer

Syntax

ftell ( resource $handle ) : int

Parameters

handle

The file pointer must be valid, and must point to a file successfully opened by fopen() or popen(). ftell() gives undefined results for append-only streams (opened with "a" flag).

Return

Returns the position of the file pointer referenced by handle as an integer; i.e., its offset into the file stream. If an error occurs, returns FALSE.

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

<?

$filename = $_SERVER['DOCUMENT_ROOT'] . '/assets/txt/file.txt';
$mode = 'r';

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

    fgets($handle, 3);

    $return = ftell($handle);

    echo $return;

fclose($handle);

?>
