如何跨两个文件访问变量 [英] How to access a variable across two files

问题描述

我有三个文件-global.php, test.php，test1.php

Global.php

Global.php

$filename;
$filename = "test";

test.php

$filename = "myfile.jpg";
echo $filename;

test1.php

test1.php

echo $filename;

我可以通过以下方式从test和test1文件中读取此变量: include 'global.php';

I can read this variable from both test and test1 files by include 'global.php';

现在我想在test.php中设置$filename的值，并在test1.php.

Now i want to set the value of $filename in test.php and the same value i want to read in test1.php.

我也尝试使用会话变量，但是由于两个不同的文件，我无法捕获该变量.

I tried with session variables as well but due to two different files i am not able to capture the variable.

如何实现这一目标........

推荐答案

使用:

global.php

global.php

<?php
if(!session_id()) session_start();
$filename = "test";
if(!isset($_SESSION['filename'])) {
    $_SESSION['filename'] = $filename;
}
?>

test.php

<?php
if(!session_id()) session_start();
//include("global.php");
$_SESSION['filename'] = "new value";
?>

test1.php

test1.php

<?php
if(!session_id()) session_start();
$filename = $_SESSION['filename'];
echo $filename; //output new value
?>
