Fseek

(PHP3, PHP4)

Fseek---&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; Moving file Metrics

Syntax: int fseek (int fp, int offset [, int whence])

Description:

Sets the location of the file indicator FP, which is specified by whence to increase the offset to the new position, whence has the following values:

Seek_set--Sets the new position equal to the bytes bit tuple

Seek_cur--Set new position for current position plus bytes

Seek_end--Set new to end of file plus bytes

If whence is not specified, it is assumed to be seek_set.

Success returns 0, otherwise it returns 1. Note: This move location is not considered an error if the file ends at the end.

This file metric cannot be used if fopen () is opening a file with "http://" or "ftp://".

Note: The whence parameter is added after the PHP 4.0rc1 version.
