PHP Functions Essential Reference

fclose

bool fclose(resource file_handle) 

Closes a file.

Returns:

TRUE on success; FALSE on error

Description:

Closes a file opened by fopen() or fsockopen(). Closing a file handle ensures that any buffered data is written to the file. This behavior can be the cause of relatively subtle bugs when working with files.

Warning:

3.0.6, 3.0.11: Doesn’t seem to close TCP sockets on Linux, already reported with 3.0.6.

3.0.7: May cause PHP to crash on Red Hat Linux 5.2.

Example:

Open and close a file

$fh = fopen ("test.txt", "r"); fclose ($fh);
