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.
