Grab the first snippet of php code with RegEx

Question

I have several files with 2 php snippets nested with

<? php code code code ?> <? php code code code ?>

How can I just grab the first snippet including tags with RegEx?

Thanks!

Have you tried anything yet? Are you executing the regex in PHP as well? — chris85, Jun 13 '16 at 20:19

Let's say a.php has this:

<?php code code code ?> <?php mocode mocode mocode ?>

Now we can get the first result using this answer

<?php

function get_string_between($string, $start, $end){
    $string = ' ' . $string;
    $ini = strpos($string, $start);
    if ($ini == 0) return '';
    $ini += strlen($start);
    $len = strpos($string, $end, $ini) - $ini;
    return substr($string, $ini, $len);
}

$fullstring = file_get_contents('a.php');

$tag1 = '<?php';
$tag2 = '?>';

echo $tag1.get_string_between($fullstring, $tag1, $tag2).$tag2;

It won't be visible in the regular browser window since it will be rendered as an invisible HTML tag, but the output will be visible in source as:

<?php code code code ?>

Thanks a ton! I have been trying some differant regexs but getting no where. This is helpful. — Voldie, Jun 13 '16 at 20:33

How about this?

$re = "/<\\?php(.+?)\\?>/i"; 
$str = "<?php some code in here ?> <?php some other code in here ?>"; 

preg_match($re, $str, $matches);
print_r($matches);

Results in this:

Array
(
    [0] => <?php some code in here ?>
    [1] =>  some code in here 
)

You also should search and try by your own please!
