把预定义的 HTML 实体 "<"(小于)和 ">"(大于)转换为字符:
<?php
$str = "This is some <b>bold</b> text.";
echo htmlspecialchars_decode($str);
?>
$str = "This is some <b>bold</b> text.";
echo htmlspecialchars_decode($str);
?>
上面代码的 HTML 输出如下(查看源代码):
<!DOCTYPE html>
<html>
<body>
This is some <b>bold</b> text.
</body>
</html>
<html>
<body>
This is some <b>bold</b> text.
</body>
</html>
上面代码的浏览器输出如下:
This is some bold text.
