Description

string socket_strerror ( int errno)

Aviso

Esta función es EXPERIMENTAL. Esto significa que el comportamiento de esta función, el nombre de esta función y en definitiva TODO lo documentado sobre esta función, puede cambiar en una futura version de PHP SIN AVISO. La advertencia queda hecha, y utilizar esta extensión queda bajo su propia responsabilidad.

socket_strerror() takes as its errno parameter a socket error code as returned by socket_last_error() and returns the corresponding explanatory text. This makes it a bit more pleasant to figure out why something didn't work; for instance, instead of having to track down a system include file to find out what '-111' means, you just pass it to socket_strerror(), and it tells you what happened.

Ejemplo 1. socket_strerror() example
<?php if (false == ($socket = @socket_create(AF_INET, SOCK_STREAM, SOL_TCP))) { echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n"; } if (false == (@socket_bind($socket, '127.0.0.1', 80))) { echo "socket_bind() failed: reason: " . socket_strerror(socket_last_error($socket)) . "\n"; } ?>
The expected output from the above example (assuming the script is not run with root privileges):
socket_bind() failed: reason: Permission denied
