一個PHP並發訪問實例代碼

復制代碼 代碼如下:
<?php
$start=$_GET['s'];
$end=$_GET['e'];

$requests = array();
for ($index = $start; $index < $end; $index++) {
$url="http://www.essort.com/amfphp/services/curl/loadTest.php?uid=$index";
$requests[]=$url;
}

$main = curl_multi_init();
$results = array();
$errors = array();
$info = array();
$count = count($requests);
for($i = 0; $i < $count; $i++) {
$handles[$i] = curl_init($requests[$i]);
var_dump($requests[$i]);
curl_setopt($handles[$i], CURLOPT_URL, $requests[$i]);
curl_setopt($handles[$i], CURLOPT_RETURNTRANSFER, 1);
curl_multi_add_handle($main, $handles[$i]);
}
$running = 0;

do {
curl_multi_exec($main, $running);
} while($running > 0);

for($i = 0; $i < $count; $i++)
{
$results[] = curl_multi_getcontent($handles[$i]);
$errors[] = curl_error($handles[$i]);
$info[] = curl_getinfo($handles[$i]);
curl_multi_remove_handle($main, $handles[$i]);
}
curl_multi_close($main);
var_dump($results);
var_dump($errors);
var_dump($info);

?>
