You can use a more advanced approach by using the protected interface of
the HttpRequestPool class. This allows you to perform some other tasks
while the requests are executed.
<?php
class Pool extends HttpRequestPool
{
public function __construct()
{
parent::__construct(
new HttpRequest('http://pear.php.net', HTTP_METH_HEAD),
new HttpRequest('http://pecl.php.net', HTTP_METH_HEAD)
);
// HttpRequestPool methods socketPerform() and socketSelect() are
// protected; one could use this approach to do something else
// while the requests are being executed
print "Executing requests";
for ($i = 0; $this->socketPerform(); $i++) {
$i % 10 or print ".";
if (!$this->socketSelect()) {
throw new HttpException("Socket error!");
}
}
print "\nDone!\n";
}
}
try {
foreach (new Pool as $r) {
echo "Checking ", $r->getUrl(), " reported ", $r->getResponseCode(), "\n";
}
} catch (HttpException $ex) {
print $e;
}
?>
