PHP html_entity_decode不按预期解码实体？

Question

在下面的代码：

$string1 = "function doesn't work as expected"; 
$string2 = html_entity_decode($string1); 

$字符串2仍包含：

' 

...之后调用html_entity_decode（）。

我已经检查过有关此主题的其他SO线程，但还没有找到答案。我错过了什么？

default flags对于html_entity_decode不包括单引号。尝试更新您的标志参数以包含ENT_QUOTES和ENT_HTML5：

$string1 = "function doesn't work as expected"; 
echo $string2 = html_entity_decode($string1, ENT_QUOTES|ENT_HTML5); 
// function doesn't work as expected
