ftell
PHP 4, PHP 5, PHP 7, PHP 8
ftell - Returns the current position of the file read/write pointer
Manual
ftell(
resource$stream ): int|false
Returns the position of the file pointer referenced by stream.
Parameters
- stream
-
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 Values
Returns the position of the file pointer referenced by stream 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.
