PHP实现HTML标签自动补全代码

一般情况下先用PHP的 strip_tags 函数去掉所有html标签，再去掉空格等，然后再用substr或者自己实现的cn_substr函数来实现截取。因为如果不先去掉html标签，直接截取出来的字符串就会有没有闭合的标签出现，有时甚至会截取在标签上面比如复制代码代码如下: </di ... 今天遇到一个内容翻页截取问题：正文是用富文本编辑器写入的，编辑器上有个分页按钮，点击之后就往当前光标位置插入一个蓝色的复制代码代码如下: <hr /> 横线。...

ThinkPHP模板判断输出Defined标签用法详解【代码】

ThinkPHP模板引擎的defined标签用于判断常量是否已经被定义。 ThinkPHP的defined标签用来判断常量是否已经被定义，其功能相当于PHP中的defined()函数。defined标签用法如下： <present name="常量">要输出的内容</present>先在模块操作（如：Index/display ）里定义一个常量并输出模板： define("SITE_NAME", "脚本之家"); $this->display();在模板/Tpl/default/Index/display.html中使用defined标签如下： <defined name="SITE_NA...

thinkphp 自定义标签【代码】【图】

关于标签的个人理解是拼凑php 字符串通过eval()来进行，返回数据。过程应该是这样的，在模板中加入定义标签为<mytag:list></mytag>，那么在mvc 中解析模板的时候，用正则来匹配该标签，如果发现符合的标签就去寻找mytag 这个类，并实例调用这个类下的 list方法进行逻辑运算返回数据。在thinkphp 中扩展自定义标签下面以输出面包屑为例：参照官方内置标签类写法。在任何地方建一个你的标签类，我这里是放在Home\Myt...
