I am using PHP 5. here I am opening Multiple sockets to get page contents.
Following is my code for getting page contents.
Code: Select all
$hosts = array("example1.com","example2.com");
foreach ($hosts as $id => $host) {
$s = stream_socket_client("$host:80", $errno, $errstr, $timeout,
STREAM_CLIENT_ASYNC_CONNECT|STREAM_CLIENT_CONNECT);
if ($s) {
$sockets[$id] = $s;
$status[$id] = "in progress";
} else {
$status[$id] = "failed, $errno $errstr";
}
}
while (count($sockets)) {
$read = $write = $sockets;
$n = stream_select($read, $write, $e = null, $timeout);
if ($n > 0) {
foreach ($read as $r) {
$id = array_search($r, $sockets);
$data = fread($r,8194);
if (strlen($data) == 0) {
if ($status[$id] == "in progress") {
$status[$id] = "failed to connect";
}
fclose($r);
unset($sockets[$id]);
} else {
$status[$id] .= $data;
}
}I want to fetch page content of all the pages simultaneously.
I tried giving more then 8K here but not seems to look working
Code: Select all
$data = fread($r,8194);thanks in advance.
