在file_get_contents中获取变量（'file.php'）[重复]
问题描述：
This question already has an answer here:
I have a file called file.php with this content:
<?php
$foo = 'hello';
?>
<div id="fileContent">
<?php echo($foo) ?>
...some content here
</div>
In other file called result.php, I call the file.php with the method file_get_contents():
<div id="resultContent">
<?php echo(file_get_contents('file.php')) ?>
</div>
But, I can´t print the internal variable $foo in my result.php file. Only appears as:
<!--?php echo($q); ?-->
Can I get this result? //print hello in the result.php file
</div>

file_get_contents() reads the specified file byte by byte but does not interpret it's contents. What you are searching for is the include() directive:
<div id="resultContent">
<?php include('file.php') ?>
</div>
答
use include() instead file_get_contents()
