3、简单使用
<?php
class AsyncOperation extends Thread
{
public function __construct($arg)
{
$this->arg = $arg;
}
public function run()
{
if ($this->arg) {
printf("Hello %s\n", $this->arg);
}
}
}
$thread = new AsyncOperation("World");
if ($thread->start()) {
$thread->join();
}
?>
输出 Hello Word
<?php
header("content-Type: text/html; charset=utf-8");
class test_thread_run extends Thread
{
public $url;
public $data;
public function __construct($url)
{
$this->url = $url;
}
public function run()
{
if (($url = $this->url)) {
$this->data = model_http_curl_get($url);
}
}
}
function model_thread_result_get($urls_array)
{
foreach ($urls_array as $key => $value) {
$thread_array[$key] = new test_thread_run($value["url"]);
$thread_array[$key]->start();
}
foreach ($thread_array as $thread_array_key => $thread_array_value) {
while ($thread_array[$thread_array_key]->isRunning()) {
usleep(10);
}
if ($thread_array[$thread_array_key]->join()) {
$variable_data[$thread_array_key] = $thread_array[$thread_array_key]->data;
}
}
return $variable_data;
}
function model_http_curl_get($url, $userAgent = "")
{
$userAgent = $userAgent ? $userAgent : 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.2)';
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_TIMEOUT, 5);
curl_setopt($curl, CURLOPT_USERAGENT, $userAgent);
$result = curl_exec($curl);
curl_close($curl);
return $result;
}
for ($i = 0; $i < 10; $i++) {
$urls_array[] = array("name" => "baidu", "url" => "http://www.baidu.com/s?wd=" . mt_rand(10000, 20000));
}
$t = microtime(true);
$result = model_thread_result_get($urls_array);
$e = microtime(true);
echo "多线程：" . ($e - $t) . "\n";
$t = microtime(true);
foreach ($urls_array as $key => $value) {
$result_new[$key] = model_http_curl_get($value["url"]);
}
$e = microtime(true);
echo "For循环：" . ($e - $t) . "\n";
