What is this?

This is a collection of questions that come up every now and then about syntax in PHP. This is also a Community Wiki, so everyone is invited to participate in maintaining this list.

Why is this?

It used to be hard to find questions about operators and other syntax tokens.¹
The main idea is to have links to existing questions on Stack Overflow, so it's easier for us to reference them, not to copy over content from …

什么是最好的,首选的写作方式,如速记单线,如:

expression ? $foo : $bar

情节扭曲:我需要echo $foo或echo $bar.任何疯狂的伎俩？:)

例:

<?php $formElement->display()?>

这样没事,或者我应该提供一个; ？好吧,我想PHP解释器非常聪明,可以看到该行已完成并且由于末尾的？>而完成了表达式.对？

任何人都可以解释一下这些特殊标签在php中是什么？

<?= ?>

我在谷歌上找不到它.

这个符号在PHP中意味着<?=什么？

用法示例:

<h2>Manage Role: > (<?= $myACL->getRoleNameFromID($_GET['roleID']); ?>)</h2> 

什么是这条线的含义

<input type=text name="name" value="<?= $name ?>

如果我们要声明为PHP我们不应该写 <?php instead of <?=

谢谢

我有一个存储在变量中的php嵌套数组$myArray,下面是var在将其转储到浏览器之后的样子(它不是一个完整的输出).

<?php var_dump($myArray); ?>

输出:

array (size=4)
  'id' => string '162' (length=3)
  'content' => string 'Test content' (length=12)
  'children' => 
    array (size=16)
      0 => 
        array (size=4)
          'id' => string '29208' (length=5)
          'content' => string 'Test content 1' (length=14)
          'children' => 
            array (size=3)
              ...
      1 => 
        array (size=4)
          'id' => string '29215' (length=5)
