PHP变量传递问题。
我include了一个a.PHP文件,使用a.PHP的变量,但我写了一个函数,在这个函数里就不能访问这个变量了,1、我用参数传递进去也没有用;2、我在函数里面include 了a.PHP,也是没有用。
请问函数怎么才可以访问这个外部文件a.PHP的变量?
------解决方案--------------------
不知道你config.php是怎樣寫,我試了一下,是可以拿到的,function a中 echo $TextTpl 改為 $textTpl 就可以了。

config.php

<br /><?php<br />$textTpl = '123';<br />?><br />
Copy after login


<br />include_once("config.php");<br />echo $textTpl; //123<br />$resultS= a($textTpl);  //无显示<br /><br />function a($textTpl){<br />  echo $textTpl; // 這裡改小寫,你之前用大寫了,當然不行<br />}<br />
Copy after login


輸出 123123
------解决方案--------------------

变量是区分大小写的!

官话就是:变量是大小写敏感的

还需要再提示一下,具体在下面找
<br />function a($textTpl) <br />{<br />  echo $TextTpl;<br /><br />}<br />
Copy after login
