thinkphp框架里用linux的crontab写php的定时脚本

<?php
    $url = &#39;http://www.tp.com/index.php?m=admin&c=controller&a=action&#39;;
    $timeout = 60;
    $data = array();
    $header = array();
    $ch = curl_init();  
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // 跳过证书检查  
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, true);  // 从证书中检查SSL加密算法是否存在  
    curl_setopt($ch, CURLOPT_URL, $url);  
    curl_setopt($ch, CURLOPT_HTTPHEADER, $header);  
    curl_setopt($ch, CURLOPT_POST, true);  
    curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));  
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);   
    curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);   //CURLOPT_TIMEOUT 设置cURL允许执行的最长秒数
   
    $response = curl_exec($ch); 
   
    if($error=curl_error($ch)){  
        die($error);  
    }  
    curl_close($ch); 
    echo $response;
