Question

Is there a php.ini setting to turn <?=$phpval?>-style output on, or has someone on this project been smoking too much ASP?

As a side note, you can quickly check php syntax using online editors such as ideone. — JRL, Jan 29 '12 at 02:23

There is, but it is deprecated. You are looking for short_open_tag which enables <? (DANGER because of xml opening tags that are the same) and <?= (no danger)

As of php 5.4, <?= will be enabled even if short_open_tag is set to Off. See the documentation.

Note that `=` is always allowed in PHP 5.4, whether `short_open_tag` is on or not. – Jan 29 '12 at 02:22
@duskwuff: that's what I tried to say, but not putting the `=` between ` messed up my answer. – greg0ire Jan 29 '12 at 02:26
Note also that in php 3.3.8 (And probably earlier versions as well) it turns on/off with the short_open_tag php.ini directive.Also, if you change that setting in your ini file, restart apache and still nothing happens, make sure your using the correct ini file as shown in phpinfo(); Derp. – wedstrom Jan 29 '12 at 02:42
What?! Why are they doing that?! – Lightness Races in Orbit Feb 28 '12 at 23:09
@LightnessRacesinOrbit : What do you mean, "that"? – greg0ire Feb 29 '12 at 08:46
@greg0ire: The thing that your answer and the first comment talks about. – Lightness Races in Orbit Feb 29 '12 at 10:34
They are doing that so that people can use `=` safely, that is, whithout having `` recognized as a php opening tag. – greg0ire Feb 29 '12 at 10:41

Yes,

<?php $var = 'Hello, World!"; ?>
<?= $var ?>

Is the same as;

<?php $var = 'Hello, World!"; ?>
<?php echo $var; ?>

`=` is actually short for ` – animuson Jan 29 '12 at 02:35

Yes, Its a valid statement, and as @greg0ire mentioned you can turn it on by editing the short_open_tag in php.ini however using <?php has been known as a better practice specially if you are writing your application for sale to the public, because <?php would work with most shared hosting configurations however <? is sometimes not allowed/not activated, so its easier for users to use your script if you use <?php.
