HomeBackend DevelopmentPHP Tutorial关于POST方式传递数据的问题

最近在研究怎么用POST方式传递数据
我想得到的效果是,打开网页a,向一个网页b传递一个字符串
然后在网页b上显示这个字符串。
在网上找到一份代码,是这样的
网页a的代码:
$uri = "http://localhost/handle.php";
// 参数数组
$data = array (
        'name' => 'tanteng' 
// 'password' => 'password'
);
 
$ch = curl_init ();
// print_r($ch);
curl_setopt ( $ch, CURLOPT_URL, $uri );
curl_setopt ( $ch, CURLOPT_POST, 1 );
curl_setopt ( $ch, CURLOPT_HEADER, 0 );
curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data );
$return = curl_exec ( $ch );
curl_close ( $ch );
 
print_r($return);
?>

网页b的代码
echo 'this is the posted data';
if(isset($_POST['name'])){
    if(!empty($_POST['name'])){
        echo '您好,',$_POST['name'].'!';
    }
}
?>

在我电脑上实验的结果是打开网页b只显示  this is the posted data
而网页a上显示    您好,tanteng!
有谁能给我解释下为什么吗?如果我想让这句话在网页b上显示该怎么做?


回复讨论(解决方案)

那把a与b的代码换一下不就行了。

算我话没说清楚……
我是希望在另一个专门的页面输出我的字符串,而不是在我提交POST请求的页面上
我现在只是用php模拟POST请求,以后要变的
就比如,我用一个C程序向某个URL提交了一个POST请求,传了个字符串过去
然后我希望打开一个指定的页面,例如output.php,在这上面看到我程序传过去的字符串
刚开始学php,可能post请求的用法我理解错了……但我的需求应该说清楚了,希望各位指教我该怎么做?

可以用???或文件保存。

a.php

<?php$uri = "http://localhost/handle.php";// 参数数组$data = array (        'name' => 'tanteng' // 'password' => 'password'); $ch = curl_init ();// print_r($ch);curl_setopt ( $ch, CURLOPT_URL, $uri );curl_setopt ( $ch, CURLOPT_POST, 1 );curl_setopt ( $ch, CURLOPT_HEADER, 0 );curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data );$return = curl_exec ( $ch );curl_close ( $ch ); print_r($return);?>


handle.php
<?php$name = isset($_POST['name'])? $_POST['name'] : '';file_put_contents('tt.txt', $name, true);echo 'success';?>


b.php
<?phpecho 'this is the posted data';if(file_exists('tt.txt')){	$name = file_get_contents('tt.txt');    if(!empty($name)){        echo '您好,',$name.'!';    }}?>
