stream_set_blocking — Set blocking/non-blocking mode on a stream
Description
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
modeisFALSE, the given stream will be switched to non-blocking mode, and ifTRUE, 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.
Return Values
Returns TRUE on success or FALSE on failure.
Notes
Note:
This function was previously called as set_socket_blocking() and later socket_set_blocking() but this usage is deprecated.
