Sets blocking mode on a socket resource (PHP 4 >= 4.2.0, PHP 5)
bool socket_set_block ( resource socket )

The socket_set_block() function removes the O_NONBLOCK flag on the socket specified by the socket parameter.

When an operation (e.g. receive, send, connect, accept, ...) is performed on a blocking socket, the script will pause its execution until it receives a signal or it can perform the operation.



A valid socket resource created with socket_create() or socket_accept().

Return Values

Returns TRUE on success or FALSE on failure.


Example 2301. socket_set_block() example

= socket_create_listen(1223);


This example creates a listening socket on all interfaces on port 1223 and sets the socket to O_BLOCK mode. socket_accept() will hang until there is a connection to accept.
