curl批处理从官方demo封装

官方demo

// 创建一对cURL资源

$ch1 = curl_init();

$ch2 = curl_init();



// 设置URL和相应的选项

curl_setopt($ch1, CURLOPT_URL, "http://www.example.com/");

curl_setopt($ch1, CURLOPT_HEADER, 0);

curl_setopt($ch2, CURLOPT_URL, "http://www.php.net/");

curl_setopt($ch2, CURLOPT_HEADER, 0);



// 创建批处理cURL句柄

$mh = curl_multi_init();



// 增加2个句柄

curl_multi_add_handle($mh,$ch1);

curl_multi_add_handle($mh,$ch2);



$running=null;

// 执行批处理句柄

do {

    usleep(10000);

    curl_multi_exec($mh,$running);

} while ($running > 0);



// 关闭全部句柄

curl_multi_remove_handle($mh, $ch1);

curl_multi_remove_handle($mh, $ch2);

curl_multi_close($mh);

第一步封装--方法

function multi_post($urls)

{

    // 创建批处理cURL句柄

    $mh = curl_multi_init();



    // 创建一对cURL资源

    // 设置相应的选项

    // 增加句柄

    foreach ($urls as $key => $url) {

        $handles[$key] = curl_init($url);

        curl_setopt($handles[$key], CURLOPT_HEADER, 0);

        curl_multi_add_handle($mh, $handles[$key]);

    }



    $running=null;

    // 执行批处理句柄

    do {

        usleep(10000);

        curl_multi_exec($mh,$running);

    } while ($running > 0);



    // 关闭全部句柄

    foreach ($handles as $key => $handle) {

        curl_multi_remove_handle($mh, $handle);

    }



    curl_multi_close($mh);

}

$urls = array('http://www.shouji.com', 'http://www.baidu.com');
multi_post($urls);

第2次改版--可设置CURL参数

$options = array(

    CURLOPT_RETURNTRANSFER => 1,     // return web page 

    CURLOPT_HEADER => 0,             // don't return headers 

    CURLOPT_TIMEOUT=> 50,           // timeout on response

    CURLOPT_POST   => 1,               // sending post data 

    CURLOPT_POSTFIELDS => $post_data,

);



function multi_post($urls, $options)

{

    // 创建批处理cURL句柄

    $mh = curl_multi_init();



    // 创建一对cURL资源

    // 设置相应的选项

    // 增加句柄

    foreach ($urls as $key => $url) {

        $handles[$url] = curl_init($url);

        curl_setopt_array($handles[$url], $options);

        curl_multi_add_handle($mh, $handles[$url]);

    }



    $running=null;

    // 执行批处理句柄

    do {

        usleep(10000);

        curl_multi_exec($mh,$running);

    } while ($running > 0);



    // 关闭全部句柄

    foreach ($handles as $url => $handle) {

        $result[$url] = curl_multi_getcontent($handle);

        curl_multi_remove_handle($mh, $handle);

    }



    curl_multi_close($mh);



    if (isset($result)) {

        return $result;

    }

    return array();

}
