Question

I was wondering if functions like file_get_contents and file_put_contents exist except they grab the raw PHP code too. All the files are local so I assume something would exist for this. The only other solution I thought of for this was using the FTP library. If anyone knows a way around this please let me know! Thanks.

Example:

code.php

<?php
echo 'hello world';

text.php

<textarea>
<?php
echo file_get_contents('code.php');
?>
</textarea>

Should output:

<textarea>
<?php
echo 'hello world'; //isn't actually executed, just displayed as raw text
</textarea>

Answer 1

您需要转义HTML字符：

echo htmlentities( file_get_contents('code.php') );

Answer 2

In your above example this would work:

code.php

<?php
echo 'hello world';

text.php

<textarea>
    <?php include('code.php'); ?>
</textarea>

Answer 3

only a test not a answer (will be deleted)

index.php

<textarea rows="10">
<?php
echo file_get_contents('code.php');
?>
</textarea>

code.php

<?php
echo 'hello world';
echo 'textline 3';

output
