Question

我正在运行这段代码：

var_dump($this->string);
$this->string = htmlentities($this->string, ENT_COMPAT, "UTF-8", false);
var_dump($this->string);

它在第一个var_dump()输出字符串，但在第二个var_dump()中为空。为什么要这样做？

Answer 1

尝试在第三个参数中将"UTF-8"更改为"iso-8859-1"。这是一个众所周知的... feature introduced in PHP 5.4。我想它可以完成这项工作。

上帝该死的PHP及其开发者。

Answer 2

htmlentities(string, quotestyle, character-set)

只有三个参数

htmlentities使字符串变空
