What is syntax in PHP code?

Question

Previous I bumped into codes like this:

<?php
  $var="hello";
?>
<?=$var?>

It simply prints out the content of $var, so... is the syntax equivalent to echo $var? I'll also appreciate an answer pointing to a related manual page. Since the syntax is not searchable.

Short tags syntax ... http://php.net/manual/en/function.echo.php (see example there) — djot, Sep 08 '13 at 09:29

Yes, <?=$var?> is the same as <?php echo $var; ?>

From PHP.net manual: echo also has a shortcut syntax, where you can immediately follow the opening tag with an equals sign. Prior to PHP 5.4.0, this short syntax only works with the short_open_tag configuration setting enabled.

You can read more here.

Also, before anyone tells you not to use it, as short tag isn't always on, it is from PHP 5.4 and on. – Rich Bradshaw Sep 08 '13 at 09:38
@RichBradshaw, good point. Just added the rest of the description to cover that. – Sergio Sep 08 '13 at 09:39
