Question

以下是我的代码，但它没有显示输出。现在我暂时将yahoo.com显示为curl输出，但我的实际输出网址不同。谁能告诉我代码中的问题是什么？

<?php
    $myurl = "www.yahoo.com";
    curl_setopt ($ch, CURLOPT_URL, $myurl);
    curl_setopt ($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $result= curl_exec ($ch); //execute and get the results
    echo $result; //display the reuslt
    curl_close($ch);
?>

Answer 1

试试这个：

//Add $ch = curl_init();
$ch = curl_init();

$myurl = "www.yahoo.com";
curl_setopt ($ch, CURLOPT_URL, $myurl);
curl_setopt ($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result= curl_exec ($ch); //execute and get the results
echo $result; //display the reuslt
curl_close($ch);

Answer 2

您没有初始化卷曲使用此：

 <?php

 $myurl = "www.yahoo.com";
 $ch = curl_init();
 curl_setopt ($ch, CURLOPT_URL, $myurl);
 curl_setopt ($ch, CURLOPT_HEADER, 0);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
 $result= curl_exec ($ch); //execute and get the results
 echo $result; //display the reuslt
 curl_close($ch);
 ?>

卷曲输出未显示
