Question

使用curl_multi，我已经加载了3个url然后打印了数组。

1）我怎样才能在输出上设置时间戳，让我知道每个网址的运行时间？

2）如何将数组分解为仅显示数据和时间戳，不包括文本“Array（[0] =＆gt;”，“[1] =＆gt;”，“[2] =＆gt;”和“）”？

代码

<?php

function multiRequest($data, $options = array()) {

  // array of curl handles
  $curly = array();
  // data to be returned
  $result = array();

  // multi handle
  $mh = curl_multi_init();

  // loop through $data and create curl handles
  // then add them to the multi-handle
  foreach ($data as $id => $d) {

    $curly[$id] = curl_init();

    $url = (is_array($d) && !empty($d['url'])) ? $d['url'] : $d;
    curl_setopt($curly[$id], CURLOPT_URL,            $url);
    curl_setopt($curly[$id], CURLOPT_HEADER,         0);
    curl_setopt($curly[$id], CURLOPT_RETURNTRANSFER, 1);

    // post?
    if (is_array($d)) {
      if (!empty($d['post'])) {
        curl_setopt($curly[$id], CURLOPT_POST,       1);
        curl_setopt($curly[$id], CURLOPT_POSTFIELDS, $d['post']);
      }
    }

    // extra options?
    if (!empty($options)) {
      curl_setopt_array($curly[$id], $options);
    }

    curl_multi_add_handle($mh, $curly[$id]);
  }

  // execute the handles
  $running = null;
  do {
    curl_multi_exec($mh, $running);
  } while($running > 0);

  // get content and remove handles
  foreach($curly as $id => $c) {
    $result[$id] = curl_multi_getcontent($c);
    curl_multi_remove_handle($mh, $c);
  }

  // all done
  curl_multi_close($mh);

  return $result;
}



$data = array(array(),array());

$data[0]['url']  = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Pearl+Jam&output=json';
$data[1]['url']  = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Black+Eyed+Peas&output=json';
$data[2]['url']  = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Nirvana&output=json';

$r = multiRequest($data);

print_r($r);

?>

输出

Array ( [0] => Pearl Jam <br>
        [1] => Black Eyed Peas<br>
        [2] => Nirvana )

首选输出

01:00:01 Pearl Jam <br>
01:00:02 Black Eyed Peas<br>
01:00:03 Nirvana

我会说保持简单...只需做一个循环，你设置时间戳并进行一次卷曲调用，然后爆炸结果阵列并过滤掉你不需要的所有键或值。

对于卷曲电话：

$r= array();

foreach($urls as $url) {
 $r[]["timestamp"]= time();
 $output= curl_exec($url);
 $r[]["bandname"]= $output;
}

你的最后一个循环就像是

foreach($r as $key=>$value){
 print $value["timestamp"];
 print $value["bandname"];
 print "<br>";
}

爆炸数组并为数组中的每个数据位添加执行时间戳？
