Question

What Im Trying to do here is set up some sort of filter.

I have no source code at the moment, but I can type it up quick after i find out how to do this.

So Say I have

$Variable1 = "The Brown Fox Jumps";

I want a If statement where

IF $Variable1 contains a word from a .txt file (filter.txt) Then $Variable1 = "Filtered"

so if the text file contained

Hey
Hi
Jump
Brown

It would change the whole thing to filtered. I Dont know how I would write that, so a little help typing it would be nice 🙂

Thanks Guys

If you file is delimeted by newlines:

$file = file_get_contents('filter.txt');
$bad_words = explode(PHP_EOL, $file); // If PHP_EOL doesn't work there are other EOL characters you can try.
$variable1 = "This is some string."
$compare = explode(' ', $variable1);
if(count(array_intersect($bad_words, $compare)) > 0){
  $variable1 = 'Filtered';
}
