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.111com.net>";
Outputs: A 'quote' is <b>bold</b>
$s = htmlspecialchars($str);
echo $s;
Outputs: A 'quote' is <b>boldwww.111com.net</b>
echo html_entity_decode($s);

再看一个实例
$str = "John & 'Adams'";
echo html_entity_decode($str);
echo "
";
echo html_entity_decode($str, ENT_QUOTES);
echo "

echo html_entity_decode($str, ENT_NOQUOTES);
?>浏览器输出：

John & 'Adams'
John & 'Adams'如果在浏览器中查看源代码，会看到这些 HTML：
