html_entity_decode() 将 HTML 实体转成字符原型

html_entity_decode(包含HTML 实体的字符串, 可选如何解码引号, 可选字符编码集)

<?<span php
</span><span function</span> showCode(<span $s</span>){<span return</span> <span str_replace</span>('&', '&', <span $s</span><span );}
</span><span //</span><span  由于转成HTML实体后，输出依旧是原字符，所以这里对 & 替换成 & 可以输出源代码格式，如果不用这个替换，您可以通过查看输出的 $html 源代码，能够看到一样的结果。</span>

<span $weigeti</span> = '-->"E.V-Get.com"<--'<span ;

</span><span $html</span> = <span htmlentities</span>(<span $weigeti</span>,<span  ENT_QUOTES);

</span><span echo</span> showCode(<span $html</span><span );
</span><span //</span><span  输出【-->"E.V-Get.com"<--】</span>

<span $entity</span> = <span html_entity_decode</span>(<span $html</span><span );
</span><span echo</span> showCode(<span $entity</span><span );
</span><span //</span><span  输出【-->"E.V-Get.com"<--】</span>

<span $entity_noquotes</span>=<span html_entity_decode</span>(<span $html</span>,<span  ENT_NOQUOTES);
</span><span echo</span> showCode(<span $entity_noquotes</span><span );
</span><span //</span><span  输出【-->"E.V-Get.com"<--】</span>
