Description
int
ftell ( resource handle)

If an error occurs, returns FALSE.
The file pointer must be valid, and must point to a file successfully opened by fopen() or popen().
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);
?> |
