本文实例讲述了PHP模板引擎Smarty内置变量调解器用法。分享给大家供大家参考,具体如下:

Smarty 中的变量调解器相当于函数,其调用方式为:通过 "|" 后面直接跟调解器函数名,如果有参数,得加在 ":" 后面,多个参数的话,累加即可。

下面为您介绍 Smarty 中内置的变量调解器:

1、capitalize

将变量里的所有单词首字大写。参数值 boolean 型决定带数字的单词,首字是否大写。默认不大写

index.php

$tpl->assign('str', 'hello world wor2ld!!!');
$tpl->display('index.html');

Copy after login

index.html(模板文件)

<{$str|capitalize}>
<{$str|capitalize:true}>

Copy after login

结果为:Hello World wor2ld!!!、 Hello World Wor2Ld!!!

2、count_characters

计算变量里的字符数,该调解器默认不计算空格(空格、制表符、回车…)只计算字符的个数,并且能很好的支持中文字符计算;如果添加参数 true ,则计算空格。

index.html

<{$str|count_characters}> // 不计算空格
<{$str|count_characters:true}> // 计算空格

Copy after login

结果为:13、14

3、cat

连接字符串,将cat里的值连接到给定的变量后面。

<{$str|cat:' Happy new year.'}>

Copy after login

结果为:hello world!!! Happy new year.

4、count_paragraphs

计算段数,计算变量里的段落数量,完美支持中文段落。

index.php

$str = <<assign('str', $str);
$tpl->display('index.html');

Copy after login

index.html

<{$str|count_paragraphs}>

Copy after login

结果为:3

5、count_sentences

计算句数,计算变量里句子的数量。注:只支持英文语句,不支持中文。

index.php

$str = <<assign('str', $str);

Copy after login
Copy after login

index.html

<{$str|count_sentences}>

Copy after login

结果为:2

6、count_words

计算词数,计算变量里的词数。

index.php

$str = <<assign('str', $str);

Copy after login
Copy after login

index.html

<{$str|count_words}>

Copy after login

结果为:12

7、date_format

日期格式化,具体参数很多,这里只举例中国式日期格式

index.php

$tpl->assign('date', time()); // 传递时间戳

Copy after login

index.html

<{$date|date_format:'%Y-%m-%d %H:%M:%S'}>

Copy after login

结果为:2012-01-26 14:37:22

8、default

默认,为空变量设置一个默认值,当变量为空或者未分配的时候,将由给定的默认值替代输出。

index.php

$tpl->assign('str', ''); // 赋值给空

Copy after login

index.html

<{$str|default:'默认输出...'}>、<{$string|default:'没有定义,默认输出...'}>

Copy after login

结果为:默认输出...、没有定义,默认输出...

9、escape

转码,用于 html 转码,url 转码,在没有转码的变量上转换单引号,十六进制转码,十六进制美化,或者 javascript 转码,默认是html转码

index.php

$html = <<Google
html;
$js = <<
  for (var i=0; i<100; i++) {
    window.alert(i);
  }
js;
$tpl->assign('html', $html); // html
$tpl->assign('url', 'http://www.google.com.hk'); // url
$tpl->assign('js', $js); // javascript

Copy after login

index.html

HTML 转码:<{$html|escape:"html"}>
URL 转码:<{$url|escape:"url"}>
JS 转码:<{$js|escape:"javascript"}>

Copy after login

结果为:

HTML 转码:Google
URL 转码:http%3A%2F%2Fwww.google.com.hk
JS 转码:

Copy after login

10、indent

缩进,每行缩进字符串,第一个参数指定缩进多少个字符串,默认是四个字符;第二个参数,指定缩进用什么字符代替。

11、lower

小写,将变量字符串小写。

使用方法:<{$str|lower}>

12、upper

大写,将变量改为大写。

使用方法:<{$str|upper}>

13、nl2br

换行符替换成

所有的换行符将被替换成 ,同php的nl2br()函数一样。

14、regex_replace

正则替换,寻找和替换正则表达式,和 preg_replace() 的语法一样。

index.php

$tpl->assign('str', 'http://www.google.com');

Copy after login

index.html

<{$str|regex_replace:'/go{2}gle/':'baidu'}>

Copy after login

结果为:http://www.baidu.com

15、replace

替换,简单的搜索和替换字符串。

16、spacify

插空,插空(不知道这个词是什么意思,顾名思义了^^)是一种在字符串的每个字符之间插入空格或者其他的字符(串)。

index.php

$tpl->assign('str', 'hello world!!!');

Copy after login

index.html

<{$str|spacify:"^^"}>

Copy after login

结果为:h^^e^^l^^l^^o^^ ^^w^^o^^r^^l^^d^^!^^!^^!

17、string_format

字符串格式化,是一种格式化浮点数的方法,例如:十进制数.使用 sprintf 语法格式化。

index.php

$tpl->assign('num', 23.5787446);

Copy after login

index.html

<{$num|string_format:"%.2f"}>
<{$num|string_format:"%d"}>

Copy after login

结果为:23.58、23

18、strip

替换所有重复的空格、换行、tab 为单个

index.php

$tpl->assign('str', "Grandmother of\neight makes\t  hole in one.");

Copy after login

index.html

<{$str|strip:" "}>

Copy after login

结果为:Grandmother of eight makes hole in one.

源代码:

Grandmother of eight makes hole in one.

19、strip_tags

去除在<和>之间的所有标签,包括<和>。

index.php

$tpl->assign('str', "Google");

Copy after login

index.html

<{$str|strip_tags}>

Copy after login

结果为:Google(源代码也是 Google,去掉了标签和标签)

20、truncate

截取,截取字符串开始的一段.默认是80个,你可以指定第二个参数作为在截取的那段字符串后加上什么字符,默认情况下,smarty会截取到一个词的末尾,如果你想要精确的截取多少个字符,把第三个参数改为"true" 。

index.php

代码如下:

$tpl->assign('str', '从前有座山,山上有座庙。庙里有一个老和尚和一个小和尚...');

index.html

<{$str|truncate:10:'...':true}>

Copy after login

结果为:从前有座山,山...

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,
