socket_set_option()

socket_set_option - Sets socket options for the socket

Syntax

bool socket_set_option (resource $socket, int $level, int $optname, mixed $optval)

Arguments

• socket - A valid socket resource created with socket_create() or socket_accept().
• level - The level parameter specifies the protocol level at which the option resides. For example, to retrieve options at the socket level, a level parameter of SOL_SOCKET would be used. Other levels, such as TCP, can be used by specifying the protocol number of that level. Protocol numbers can be found by using the getprotobyname() function.
• optname - The available socket options are the same as those for the socket_get_option() function.
• optval - The option value.

Description

The socket_set_option() function sets the option specified by the optname parameter, at the specified protocol level, to the value pointed to by the optval parameter for the socket.
