PHP Functions
Function: ftell (PHP 3, PHP 4, PHP 5) ftell -- Tells file pointer read/write positionDescriptionint ftell ( resource handle )Returns the position of the file pointer referenced by handle ; i.e., its offset into the file stream. If an error occurs, returns FALSE . 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).
Example 1. ftell() example <?php // opens a file and read some data $fp = fopen("/etc/passwd", "r"); $data = fgets($fp, 12); // where are we ? echo ftell($fp); // 11 fclose($fp); ?> Related Function(s) |
