ftruncate -- Truncates a file to a given length


bool ftruncate ( resource handle, int size)

Takes the filepointer, handle, and truncates the file to length, size. Returns TRUE on success or FALSE on failure.

Note: Prior to PHP 4.3.3, ftruncate() returns an integer value of 1 on success, instead of boolean TRUE.
