I create some socket with stream_socket_client()
, and put them in a array named $sockets
.
When I run the code, an error is coming:
Strict Standards: Only variables should be passed by reference in D:\www\study\cl\s.php on line 63
Code:
while (count($sockets)) {
$read = $write = $sockets;
stream_select($read, $write, $e = null, $timeout); //line 63
if (count($read)) {
foreach ($read as $r) {
$id = array_search($r, $sockets);
$data = fgets($r, 1024);
echo $data;
if (strlen($data) == 0) {
if ($status[$id] == "in progress") {
$status[$id] = "failed to connect";
}
fclose($r);
unset($sockets[$id]);
} else {
$status[$id] .= $data;
}
}
foreach ($write as $w) {
$id = array_search($w, $sockets);
fwrite($w, "HEAD / HTTP/1.0rnHost: " . $host . "rnrn");
$status[$id] = "waiting for response";
}
} else {
foreach ($sockets as $id => $s) {
$status[$id] = "timed out " . $status[$id];
}
break;
}
}
