Replace ' and similar html codes with their correspondent character?
提问by Jonas Kaufmann
so I have a string that goes like this:
所以我有一个像这样的字符串：
$string = "This is a test string. It has characters like these: '";
Is there a php function that transforms these to their correspondent character, in my example the desired output would be:
是否有一个 php 函数可以将它们转换为对应的字符，在我的示例中，所需的输出是：
print $string
// OUTPUT: This is a test string. It has characters like these: '
回答by Yaron U.
yes there is:
htmlspecialchars_decode($string, ENT_QUOTES);
就在这里：
htmlspecialchars_decode($string, ENT_QUOTES);
not sure about the specific 'char, as far as I know htmlspecialchars(with ENT_QUOTESflag) convert an apostrophe (') to '(with a leading zero)
不确定具体的'字符，据我所知htmlspecialchars（带ENT_QUOTES标志）将撇号（'）转换为'（带前导零）
so the exact behavior on 'worth checking
所以'值得检查 的确切行为
EDIT: I made the test and it does work :)
编辑：我做了测试，它确实有效:)

You can use html_entity_decode()
您可以使用html_entity_decode()
It's like reverse htmlentities. If you use quotes in your input string you have to set the second parameter of html_entity_decode()to ENT_QUOTES
这就像反向htmlentities。如果在输入字符串中使用引号，则必须将第二个参数设置html_entity_decode()为ENT_QUOTES
