What does this symbol mean in PHP <?= (4 answers)

Closed 8 years ago.

I'm using CakePHP.

Today I tried to link a page of the Page Controller to another page from the Page controller, and I couldn't get to see the link until I wrote

<?= $this->Html->link('myPage', array('controller' => 'pages', 'action' =>
    'myPage')); ?>

Why did I have to write <?= and not <?php ?

Generally speaking, when do I have to use <?= and when <?php ?

Answer 1

<?= is short for <?php echo

Add echo to your code and it will work.

This is not unique to CakePHP, it's just part of PHP.
