PHP - 变量，仅允许文本

Question

I am making a website (dah), and I need to have a function.

That function would make the string in only text.

Like:

$string = "Hello world<div width="100000">aaa</div>";

In html, that would get very bad. I am trying to use a function to make this in text, like:

$string = function($string);

And that would only return solid text!

You're looking for strip_tags(), which will remove the harmful tags from the input:

$string = strip_tags( 'Hello world<div width="100000">aaa</div>');
echo $string; // Output: Hello worldaaa
