关于html_entity_decode在大多数情况下是与htmlspecialchars htmlentities配合使用的.

html_entity_decode用法:

string html_entity_decode(string $string [,int $quote_style = ENT_COMPAT [, string $charset ]]).

html_entity_decode() 函数把 HTML 实体转换为字符.

html_entity_decode() 是 htmlentities() 的反函数也html_entity_decode() 是 htmlspecialchars() 的反函数.

$str = "A 'quote' is bold www.phpfensi.com";

Outputs: A 'quote' is bold

$s = htmlspecialchars($str);

echo $s;

Outputs: A 'quote' is boldwww.111cn.net

echo html_entity_decode($s);

A 'quote' is bold

再看一个实例,代码如下:

$str = "John & 'Adams'";

echo html_entity_decode($str);

echo "";

echo html_entity_decode($str, ENT_QUOTES);

echo "";

echo html_entity_decode($str, ENT_NOQUOTES);

?>//开源代码phpfensi.com

//浏览器输出：

John & 'Adams'

John & 'Adams'

John & 'Adams'
