PHP htmlentities不起作用

Question

I am retrieving text and HTML tags from a database while using this function to encode the values for the browser.

foreach ($row as $key => &$value){
    $value = htmlspecialchars_decode(
                 htmlentities($value,ENT_QUOTES), 
                 ENT_NOQUOTES
             );
}

Basically, I am looping through each row and converting quotes, single quotes, and other special characters to entities while keeping HTML tags.

However, when there's tags like <a href="example.com"> , the quotes are duplicated twice and outputs to this:

<a href=""example.com""> .

What am I doing wrong?

Answer 1

您应该使用htmlentities： htmlentities($str, ENT_QUOTES);
