string socket_strerror ( int $errno )

socket_strerror() takes as its errno parameter a socket error code as returned by socket_last_error() and returns the corresponding explanatory text.

Although the error messages generated by the socket extension are in English, the system messages retrieved with this function will appear depending on the current locale (LC_MESSAGES).

范例

Example #1 socket_strerror() example

<?php
if (false == ($socket = @socket_create(AF_INETSOCK_STREAMSOL_TCP))) {
   echo 
"socket_create() failed: reason: " socket_strerror(socket_last_error()) . " ";
}

if (
false == (@socket_bind($socket'127.0.0.1'80))) {
   echo 
"socket_bind() failed: reason: " socket_strerror(socket_last_error($socket)) . " ";
}
?>

The expected output from the above example (assuming the script is not run with root privileges):

socket_bind() failed: reason: Permission denied
