PHP: <?= not working / Apache configuration issue?

Question

I've ran into this issue before but don't remember what was causing it. I have a small app that uses the shorthand notation to print variables, <?=$myvar?>, but it doesn't seem to get parsed by the webserver?

Any ideas on what might be wrong here? It's a bit weird since everything else is working ok.

Thanks!

Check the output of phpinfo() and see if short_open_tag is on. — SenorAmor

Thanks for that Mike - I couldn't find it because I didn't know I should be searching for "short tags" so sorry about that. I don't mind if it's getting closed, I'm just thinking that people that run into this issue would most likely search for "<?=" issues. If I knew to search for short tags, I would have probably spotted it in phpinfo(). — Claudiu

@Claudiu StackOverflow search doesn't seem to work with <?=, and Google doesn't post any helpful results either. — Mike B

its a short open tag with an echo command (=). since php 5.4 its no longer marked as short open tag and therefore works even with php.ini setting short_open_tags set to off beginning with that version. for earlier versions it depends on that option.

more information:

http://php.net/manual/en/ini.core.php#ini.short-open-tag

you can check that option e.g. using $sot = ini_get('short_open_tags');

I was just about to say the same myself! For reference, php.net/manual/en/ini.core.php#ini.short-open-tag

Thanks, this was it! Maybe you should edit the link to point to the English version though?

It may be turned off in the PHP configuration. Did you try adding this to your script?

<?php
phpinfo();
?>

Anyway, try to avoid short tags because they're good for nothing except creating a portability issue. :)

Writing less code is always better in my opinion. And as Hajo pointed out, this is future proof, just as soon as everybody updates the PHP version :) Thanks for the advice though

well <? may conflict with xml files, but <?= should be ok. when php is used as a template engine <?= might be ok, for libraries and class files i would prefer <?php

Not only check for the short_opened_tags but also be sure that AddHandler application/x-httpd-php .php is in your http.conf file. If its not there please add it and restart your apache server.
