PHP: return value from function and echo it directly?
提问by matt
this might be a stupid question but …
这可能是一个愚蠢的问题，但是……
php
php
function get_info() {
$something = "test";
return $something;
}
html
html
<div class="test"><?php echo get_info(); ?></div>
Is there a way to make the function automatically "echo" or "print" the returned statement? Like I wanna do this …?
有没有办法让函数自动“回显”或“打印”返回的语句？就像我想做这个……？
<div class="test"><?php get_info(); ?></div>
… without the "echo" in it?
......没有“回声”吗？
Any ideas on that? Thank you in advance!
对此有何想法？先感谢您！

You can use the special tags:
您可以使用特殊标签：
<?= get_info(); ?>
Or, of course, you can have your function echo the value:
或者，当然，您可以让函数回显值：
function get_info() {
$something = "test";
echo $something;
}

Why return when you can echo if you need to?
如果需要，为什么可以回声时返回？
function
get_info() {
$something = "test";
echo $something;
}
回答by Eugen Rieck
Why not wrap it?
为什么不包起来？
function echo_get_info() {
echo get_info();
}
and
和
<div class="test"><?php echo_get_info(); ?></div>

Have the function echo the value out itself.
让函数自己回显值。
function get_info() {
$something = "test";
echo $something;
return $something;
}

One visit to echo's Manual page would have yielded you the answer, which is indeed what the previous answers mention: the shortcut syntax.
访问echo的手册页就会得到答案，这确实是之前的答案提到的：快捷语法。
Be very careful though, if short_open_tagis disabled in php.ini, shortcutting echo's won't work, and your code will be output in the HTML. (e.g. when you move your code to a different server which has a different configuration).
但是要非常小心，如果short_open_tag在 中禁用php.ini，则快捷方式 echo 将不起作用，并且您的代码将在 HTML 中输出。（例如，当您将代码移动到具有不同配置的不同服务器时）。
For the reduced portability of your code I'd advise against using it.
为了降低代码的可移植性，我建议不要使用它。

Sure,
当然，
Either print it directly in the function:
要么直接在函数中打印它：
function get_info() {
$something = "test";
echo $something;
}
Or use the PHP's shorthand for echoing:
或者使用 PHP 的速记来回显：
<?= get_info(); ?>
Though I recommend you keep the echo. It's more readable and easier to maintain returning functions, and the shorthands are not recommended for use.
虽然我建议你保留回声。返回函数可读性更强，更容易维护，不推荐使用简写。
