反向htmlspecialchars [英] reverse htmlspecialchars

问题描述

这似乎是一个简单的问题，但我无法在档案中找到它.

this may seem like a simple problem but I couldn't find it in the archives.

如何逆转htmlspecialchars的影响?

how does one reverse the effects of htmlspecialchars?

我尝试过这样的事情:

$trans_tbl = get_html_translation_table (HTML_ENTITIES);
$trans_tbl = array_flip ($trans_tbl);
$html = strtr ($html, $trans_tbl);

但是没有用.有没有简单的方法可以做到这一点?

but it didn't work. is there a simple way to do this?

推荐答案

使用htmlspecialchars_decode()

<?php
$str = "<p>this -&gt; &quot;</p>\n";

echo htmlspecialchars_decode($str);

// note that here the quotes aren't converted
echo htmlspecialchars_decode($str, ENT_NOQUOTES);
?>
