touch

Description

bool touch ( string filename [, int time [, int atime]] )

Attempts to set the access and modification time of the file named by filename to the value given by time. If the parameter time is not given, uses the present time. This is equivalent to what utime (sometimes referred to as utimes) does. If the third parameter atime is present, the access time of the given filename is set to the value of atime. Note that the access time is always modified, regardless of the number of parameters.

If the file does not exist, it is created. Returns TRUE on success or FALSE on failure.

Example 1. touch() example <?php if (touch($FileName)) {     echo "$FileName modification time has been changed to present time"; } else {     echo "Sorry, could not change modification time of $FileName"; } ?>
