Combining variables

[thefisherman]

Hi!

Okay, i'll try to explain.

Let's say i have 4 variables, or an array which holds 4 elements, for instance:

$a="car";
$b="red";
$c="nice";
$d="classic";

Now, i have a form where users type something.
Let's say they type:

"nice red car"

or..

"classic car" etc..

Is there a way to determine whether each word exists in the pre-defined variables?

because i can detect something like that if i do this:

$e="nice red car";

but as you can imagine, there are millions of combinations when you have like 100 words.

Anyone?

thanx in advance

Use explode() to turn the string into an array, using the space as the string separator. Then run a foreach loop on the array and check if each of those elements is the array using in_array(). Very simple.
