BetterPHP

I have something like this,

if($_GET['category'] === "all") {
     //stuff
}

This only works if it's exactly "all" what if I want to run the code even if it's "ALL" or "aLl" or "aLL".

I'm hoping there is a better way than doing a bunch of || in the if statement

if(strtolower($_GET['category']) === "all") {
     //stuff
}

?

Using strtolower works to 50% percent. I was looking for something different.

I'll post again when I know how to explain it better :S

Do you want words that are a synonym of "all" to also work ?

Maybe create an array containing allowed forms of "all", then use the in_array function.

You could use strcasecmp to check if it's the same spelling but case-insensitive.

$word1 = 'test';
$word2 = 'Test';

if ( strcasecmp($word1, $word2) === 0 ) {
    echo 'They are the same!';
}

Maybe create an array containing allowed forms of "all", then use the in_array function.

Now what if you had a different word? For a three-letter word, there are only eight different combinations. However, even if you have only an eight-letter word, you already have 256 combinations! Ten letters? 1024 combinations!

Seems like that would get way too tedious

Unless you use strtolower before checking it, or that other thing you posted.

Indeed.

What kamal suggested was something like this though, I think:

$word = 'aLL';

$combinations = array('all', 'All', 'aLl', 'alL', 'ALl', 'AlL', 'aLL', 'ALL');

if ( in_array(word, $combinations) ) { echo "It's good!"; }

Which in itself is a fine solution, but, as I said, way too tedious for longer words. I mean, I don't really want to create a 1024 item long array with all different ways to write 'homeless' or something.
