live php phpstorm template grammar

关于Php要不要使用模板一直被大家讨论,支持的说使用模板更简洁,易与前端工程师交流。反对的说Php本身就支持内嵌语法,没必要再用个模板,降低性能。 其实使用Php的短语法,直接嵌入也不是很难看,该支持的循环啥的都支持,再配合PhpStorm神器的Live Templa

关于Php要不要使用模板一直被大家讨论,支持的说使用模板更简洁,易与前端工程师交流。反对的说Php本身就支持内嵌语法,没必要再用个模板,降低性能。

其实使用Php的短语法,直接嵌入也不是很难看,该支持的循环啥的都支持,再配合PhpStorm神器的Live Template,连Shift都不用按了,很省事。(其它IDE也应该有相应的代码片段功能)

先看看效果:

//输出 [stv]
= $x ?>

//if-else [stif]
 if ($x > $y): ?>
    <h4 id="x-is-greater-than-y">x is greater than y</h4>
//[stelif]
 elseif ($x == $y): ?>
    <h4 id="x-is-equal-to-y">x is equal to y</h4>
 else: ?>
    <h4 id="x-is-less-than-y">x is less than y</h4>
 endif ?>

//for [stfor]
 for ($i = 0; $i 
    <h7>= $i ?></h7>
 endfor ?>

//foreach [stfore]
 $list = array('a', 'b', 'c', 'd', 'e') ?>
 foreach($list as $val): ?>
a== $val ?>
 endforeach ?>

//foreach key=>value [stforek]
 foreach(array('a'=>1,'b' => 2) as $key => $var): ?>
= $$key ?>=>= $var ?>
 endforeach ?>

//while [stw]
 while ($i 
    <h7>= $i ?></h7>
     $i++ ?>
 endwhile ?>

//switch(这个比较讨厌,因为后面要跟break)[stsw]
 switch($i):
    case 0:
        echo '0'; break;
    case 1:
        echo '1'; break;
    case 2:
        echo '2'; break;
    default:
        echo 'N/A';
endswitch ?>
Copy after login
其中switch因为后面要跟break,所以就没有分行,而是用一个php块。不过因为短语法中的if-else也很直观,可以代替switch。我在phpstorm中还特地增加了 elseif($x == 1): ?>的片段,方便增加判断逻辑。


前提是要在php.ini中打开支持,short_open_tag = On。在SAE也支持,其它云网站还没试过。另外,PHP5.4以后,不用设置short_open_tag=on,= ?>总是可用,(但 ?>仍然需要设置php.ini来开启),说明大家对它的需求还是挺多的。实在担心兼容性的可以手动修改live template,将 ?>改为


下面就是在phpstrom中加入live template,这个就相当于语法提示,你输入前几个字母(关键字),按tab,它就自动把自定义的补上。

关键字我都写在上面代码中方括号中了。

phpstorm的配置我就不一一贴了,后面给需要的下载地址,下面是while [stw] 的示例:

 while($$$VAR$ $COND$ $COMP$): ?>
$END$
 $$$VAR$++ ?> 
 endwhile ?>
Copy after login

setting.jar的下载地址:setting.jar(其中只包括了Live Template设置,而且放在了一个自建的目录下,不用担心覆盖自己的设置。)

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
