从文件末尾获取PHP变量

Question

I have a fileA.php that contains:

<?php $cdn = 'example.org/folder/'; ?>

and file1.php , file2.php .....to.... file20000.php that have:

<?php 
$lawyer_photo = $cdn . 'lawyername_image.jpg';
include 'fileA.php';    
echo '<img src="'. $lawyer_photo . '">';
?>

Because we have fileA.php included after variable $lawyer_photo the output will not add $cdn, so instead of having :

<img src="example.org/folder/lawyername_image.jpg">

we get

<img src="lawyername_image.jpg">

Of course this is normal, but my question is if there is a way to modify fileA.php in a way that file1.php , file2.php .....to.... file20000.php will work as desired and get the $cdn variable correctly?

Any suggestion?

Answer 1

<?php 
include 'fileA.php';
$lawyer_photo = $cdn . 'lawyername_image.jpg';  
echo '<img src="'. $lawyer_photo . '">';
?>

That's the only way. You can't use a variable before it exists.
