I have been using PHP for a while now and I came across the `htmlspecialchars_decode()` function. I am a bit confused about how it works and when it should be used. I have seen it being used in some code examples, but I don't fully understand its purpose.
Here is an example of how the `htmlspecialchars_decode()` function is being used:
$text = "<p>This is a <b>bold</b> paragraph.</p>";
$decodedText = htmlspecialchars_decode($text);
Can someone please explain to me what the `htmlspecialchars_decode()` function does in this example? And maybe provide some more real-world scenarios where it would come in handy?
Thanks in advance for your help!
