<h1>HTML字符实体（Character Entities），转义字符串（Escape Sequence）</h1>
</div>
</div>

<div class="commonContainer">
<h2>为什么要用转义字符串？</h2>
<p>HTML中<，>，&等有特殊含义（<，>，用于链接签，&用于转义），不能直接使用。这些符号是不显示在我们最终看到的网页里的，那如果我们希望在网页中显示这些符号，该怎么办呢？
</p>
<p>这就要说到HTML转义字符串（Escape Sequence）了。
</p>
<p><a href="http://114.xixik.com/character/" class="f14px" title="常用HTML转义字符,html转义符">转义字符串</a>（Escape Sequence）也称字符实体(Character Entity)。在HTML中，定义转义字符串的原因有两个：第一个原因是像“<”和“>”这类符号已经用来表示HTML标签，因此就不能直接当作文本中的符号来使用。为了在HTML文档中使用这些符号，就需要定义它的转义字符串。当解释程序遇到这类字符串时就把它解释为真实的字符。在输入转义字符串时，要严格遵守字母大小写的规则。第二个原因是，有些字符在ASCII字符集中没有定义，因此需要使用转义字符串来表示。
</p>
<!-- Contents of this file are Copyright 2006-2008, Xixik Inc. -->
<h2>转义字符串的组成</h2>
<p>转义字符串（Escape Sequence），即字符实体（Character Entity）分成三部分：第一部分是一个&符号，英文叫ampersand；第二部分是实体（Entity）名字或者是#加上实体（Entity）编号；第三部分是一个分号。
</p>
<p>比如，要显示小于号（<），就可以写 &lt; 或者 &#60; 。
</p>
<p>用实体（Entity）名字的好处是比较好理解，一看lt，大概就猜出是less than的意思，但是其劣势在于并不是所有的浏览器都支持最新的Entity名字。而实体(Entity)编号，各种浏览器都能处理。
</p>
<p>提示：实体名称（Entity）是区分大小写的。
</p>
<p>备注：同一个符号，可以用“实体名称”和“实体编号”两种方式引用，“实体名称”的优势在于便于记忆，但不能保证所有的浏览器都能顺利识别它，而“实体编号”则没有这种担忧，但它实在不方便记忆。
</p>
<h2>如何显示空格？</h2>
<p>通常情况下，HTML会自动截去多余的空格。不管你加多少空格，都被看做一个空格。比如你在两个字之间加了10个空格，HTML会截去9个空格，只保留一个。为了在网页中增加空格，你可以使用&nbsp;表示空格。

<p>编程的时候要注意特殊字符的问题，很多运行时出现的问题都是因为特殊字符的出现而引起的。
</p>
<p>注意，由于反斜杠本身用作转义符，因此不能直接在脚本中键入一个反斜杠。如果要产生一个反斜杠，必须一起键入两个反斜杠 (\\)。

<p>附：</p>
<p>在php中我们可以用mbstring的mb_convert_encoding函数实现这个正向及反向的转化。 如：</p>
<p><br>
</p>
<p>mb_convert_encoding ("你好", "HTML-ENTITIES", "gb2312"); //输出：&#20320;&#22909;
</p><p>mb_convert_encoding ("&#20320;&#22909;", "gb2312", "HTML-ENTITIES"); //输出：你好
</p><p> </p>
<p>如果需要对整个页面转化，则只需要在php文件的头部加上这三行代码：</p>
<p> </p>
<p>mb_internal_encoding("gb2312"); // 这里的gb2312是你网站原来的编码
</p><p>mb_http_output("HTML-ENTITIES");
</p><p>ob_start('mb_output_handler');
