socket_last_error()

socket_last_error - Returns the last error on the socket

Syntax

int socket_last_error (resource $socket)

Arguments

• socket - A valid socket resource created with socket_create().

Description

If a socket resource is passed to this function, the last error which occurred on this particular socket is returned. If the socket resource is omitted, the error code of the last failed socket function is returned. The latter is particularly helpful for functions like socket_create() which don't return a socket on failure and socket_select() which can fail for reasons not directly tied to a particular socket. The error code is suitable to be fed to socket_strerror() which returns a string describing the given error code.

Version

PHP 4.1.0, 5

Return value

This function returns a socket error code.
