我这里需要结尾的分号吗? [英] Do I need a trailing semicolon here?

问题描述

示例:

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

可以吗?还是应该提供; ? 好吧，我猜想PHP解释器足够聪明，可以看到该行已完成，并且由于末尾的?>而使表达式完成了.对吧?

Is this fine, or should I provide a ; ? Well I guess that the PHP interpreter is clever enough to see that the line is finished and the expression done because of the ?> at the end. Right?

推荐答案

它不是必需，但是您应该把它作为一个好习惯.

It is not required, but you should put it, as a good practice.

那样，您需要在该指令之后添加另一条指令的那一天，它将很好地工作.

That way, the day you need to add another instruction after this one, it'll work fine.

这是回答您问题的手册页:指令分离 (引用，强调我的意思):

And here is the manual's page that answers your question : Instruction separation (quoting, emphasis mine) :

与C或Perl中一样，PHP要求在每个语句的末尾以分号终止指令.
一段PHP代码的结束标记会自动表示一个分号；您不需要使用分号终止PHP块的最后一行.
该块的结束标记将包含紧随其后的换行符(如果存在的话).

As in C or Perl, PHP requires instructions to be terminated with a semicolon at the end of each statement.
The closing tag of a block of PHP code automatically implies a semicolon; you do not need to have a semicolon terminating the last line of a PHP block.
The closing tag for the block will include the immediately trailing newline if one is present.
