while循环中不支持循环使用curl

<?php 

$link = mysql_connect('localhost', 'sms', 'sms');

mysql_select_db('sms', $link);

mysql_query("set names utf8");

$sql = "

SELECT phone,chang, msg, linkid, mo_time FROM tables '";



$result = mysql_query($sql,$link);

$array = array();

while($row = mysql_fetch_array($result)){





    $linkid = $row['phone'].date("YmdHis", strtotime($row['mo_time']));

    $str = "SPNUM=".$row['chang']."&MOBILE=".$row['phone']."&CONTENT=".urlencode($row['msg'])."&MOTIME=".urlencode($row['mo_time'])."&LINKID=".$linkid;



    $url = "www.baidu.com?".$str; 

    $array[] = $url;

    //var_dump($url); 这里使用curl访问，只能访问一条随后就中断了，只能在上面存放到数组中

    /*$result = file_get_contents($url);

    var_dump($result);*/

    /*$ch = curl_init($url);

    curl_setopt($ch, CURLOPT_TIMEOUT, 40);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    $result = curl_exec($ch);

     // 4. 释放curl句柄

      curl_close($ch);*/

}

//var_dump($array); 

//这里使用foreach循环执行curl命令

foreach ($array as $url) {

    var_dump($url);

    $ch = curl_init($url);

    curl_setopt($ch, CURLOPT_TIMEOUT, 40);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    $result = curl_exec($ch);

     // 4. 释放curl句柄

      curl_close($ch);

      var_dump($result);

}
