無法發送使用CURLOPT_POST到其他PHP文件

Question

我是新來的PHP，我試圖讓使用curl從網站的數據（刮）數據，

無法從index.php來data.php獲取數據，使用CURLOPT_POST ..我做錯了什麼..？

• followed this tutorial on youtube

的index.php

<?php 
$data = array("name"=>"john","age"=>31); 
$string = http_build_query($data); 

echo $string; 

$ch = curl_init("http://localhost/scrap_practise/data.php"); 
curl_setopt($ch, CURLOPT_POST,true); 
curl_setopt($ch, CURLOPT_POSTFIELDS,$string); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_exec($ch); 
curl_close($ch); 

?> 

data.php

<?php 
echo 'finlly in'; // this never echos 
if(isset($_POST['name'],$_POST['age'])){ 
    $db = new Mysqli("localhost","root","","mydb"); 
    $name = $db->real_escape_string($_POST['name']); 
     $age = (int) $_POST['age']; 
     $query = "INSERT INTO data SET data='$name,$age'"; 
     $db->query($query); 

} 

?> 

Answer 1

只要你需要更新你index.php腳本與這些代碼行。

的index.php

<?php 
$data = array("name"=>"john","age"=>31); 
$string = http_build_query($data); 

echo $string; 

$ch = curl_init("http://localhost/scrap_practise/data.php"); 
curl_setopt($ch, CURLOPT_POST,true); 
curl_setopt($ch, CURLOPT_POSTFIELDS,$string); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
if(! $result = curl_exec($ch)) 
{ 
    trigger_error(curl_error($ch)); 
} 
curl_close($ch); 

// to see the return result uncomment the below line code. 
//print_r($result); 
?>

希望這將有助於解決您的問題！

試試這個代碼，我希望它會爲你工作...

<?php 
$url = 'http://localhost/scrap_practise/data.php'; 

$data = array("name"=>"john","age"=>31); 

$string = http_build_query($data); 

echo $string; 

$ch = curl_init(); 
curl_setopt($ch,CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_POST,true); 
curl_setopt($ch, CURLOPT_POSTFIELDS,$string); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 

$result = curl_exec($ch); 
print_r($result) ; 

curl_close($ch); 

?> 

在data.php文件

<?php 
echo 'finlly in'; // this never echos 
if(isset($_POST['name'],$_POST['age'])) 
{ 
    echo "<pre>"; print_r($_POST); 
} 
?> 

這將輸出：

finlly in 
Array 
(
    [name] => john 
    [age] => 31 
)
