2. Geben Sie einen PHP-Abschnitt Threads an und For-Schleifen, PHP-Codebeispiele zum Erfassen von Baidu-Suchseiten:
<?php   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 < 100; $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"; ?>
Das Obige hat die Verwendung von echtem Multithreading in PHP vorgestellt, einschließlich einiger Aspekte davon. Ich hoffe, dass es für Freunde hilfreich sein wird, die sich für PHP-Tutorials interessieren.
