From the string.inc const ( in amxmodx.inc )

/* Checks if source contains string. On success function
* returns position in source, on failure returns -1. */
native contain(const source[],const string[]);

Means that:

new A[10] = "BlahBlah"
new B[10] = "LAHLAH"

//contain(A, B) will return -1

// So if -1 != -1

if(contain(A, B)) != -1)
{
//Something will happen if A and B match.
}

Please correct me if I'm wrong ^_^

Thanks. If, i don't put != -1, what's happening? Will return with what i want?
Like:
if(contain(A, B))
{
//Something will happen if A and B match.
}

No. if(contain(A, B)) means the answer is either positive or a negative number, i.e. != 0.
-1 means there is NO MATCH. Other than this (higher then -1) means it has a match.
