stream_set_blocking

(PHP 4 >= 4.3.0, PHP 5, PHP 7)

Set blocking/non-blocking mode on a stream

bool stream_set_blocking ( resource $stream, bool $mode )

Sets blocking or non-blocking mode on a stream.

This function works for any stream that supports non-blocking mode (currently, regular files and socket streams).

Parameters:

stream

The stream.

mode

If mode is FALSE, the given stream will be switched to non-blocking mode, and if TRUE, it will be switched to blocking mode. This affects calls like fgets() and fread() that read from the stream. In non-blocking mode an fgets() call will always return right away while in blocking mode it will wait for data to become available on the stream.

Returns:

Returns TRUE on success or FALSE on failure.

Notes:

This function was previously called as set_socket_blocking() and later socket_set_blocking() but this usage is deprecated.
