ftruncate

(PHP 4, PHP 5)

ftruncate -- Truncates a file to a given length

Description

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: The file pointer is changed only in append mode. In write mode, additional fseek() call is needed.

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

See also fopen() and fseek().
