What does '<?=' mean in PHP?

I'm reading someone else's code and I don't think I've come across this before.

if((< ? =date("Y");?>-parseInt($('#year').find('option:selected').val()))<18)

Any thoughts?

Thanks

It's worth noting that the snippet of code you've posted is javascript with embedded PHP. — John Carter, Nov 22 '11 at 21:16

<?= is the short open and echo tag. Here is the PHP documentation for it.

<?= is short-hand for <?php echo, but only works if php.ini is setup properly.

Same as <?php echo ...

It is not always enabled in some environments.

That evaluates to:

if((<?php echo date("Y"); ?>-parseInt($('#year').find('option:selected').val()))<18)

But I think its recommended for you to use <?php echo '';?> instead of <?= ?> for compatibility reasons.
