socket_last_error
SOCKET_LAST_ERROR(3) 1 SOCKET_LAST_ERROR(3)socket_last_error - Returns the last error on the socketSYNOPSIS
int socket_last_error ([resource $socket])
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(3) which don't return a socket on failure and socket_select(3) which can fail for reasons not directly tied to a particular
socket. The error code is suitable to be fed to socket_strerror(3) which returns a string describing the given error code.
PARAMETERS
o $socket
- A valid socket resource created with socket_create(3).
RETURN VALUES
This function returns a socket error code.
EXAMPLES
Example #1
socket_last_error(3) example
<?php
$socket = @socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if ($socket === false) {
$errorcode = socket_last_error();
$errormsg = socket_strerror($errorcode);
die("Couldn't create socket: [$errorcode] $errormsg");
}
?>
NOTES
Note
socket_last_error(3) does not clear the error code, use socket_clear_error(3) for this purpose.
