PHP html_entity_decode 未按预期解码实体？

在下面的代码中：

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

$string2 仍然包含：

 '

...调用 html_entity_decode() 之后。

默认标志不包含html_entity_decode单引号。尝试更新您的 flags 参数以包含ENT_QUOTESand 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
