PHP代码中的<？= $ varname？>语法是什么？ [重复]
问题描述：
This question already has an answer here:
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.

echo $ var code>的语法？ 我也很感激 回答指向相关的手册页。 由于语法不可搜索。 p> div>
答
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.
