如何将引号（'，“）从特殊字符转换为通用字符，其他标记保持特殊？

In my string I have quotes(',") and < tags > . I used

htmlspecialchars($str, ENT_QUOTES);  

to convert only the single and double quote to general text . But unfortunately it is also converting tags < , > . For this reason even I have

strip_tags("$desc","< b >< font >< i >< u >< br >"); 

Those allowed tags are also displaying as general < and > sign not working as html tags .

In conclude , I want to display single and double quote as regular text and allowed tags working as html does.

Thank You.

Why don't you run strip_tags() before htmlspecialchars() ?

sample:

<?php
$input = '<b>allowed tag</b> " <font>not allowed tag</font>';

// XXX
$tmp = htmlspecialchars($input, ENT_QUOTES);
$result = strip_tags($tmp, '<b>');
var_dump($result);
// string(78) "&lt;b&gt;allowed tag&lt;/b&gt; &quot; &lt;font&gt;not allowed tag&lt;/font&gt;"

// Improved
$tmp = strip_tags($input, '<b>');
$result = htmlspecialchars($tmp, ENT_QUOTES);
var_dump($result);
// string(53) "&lt;b&gt;allowed tag&lt;/b&gt; &quot; not allowed tag"
