PHP код:
"abc" - placed at 33
"tat" - placed at 24
// code
new array[50][64];
printf("abc = %i", getIndex(array, "abc"));
printf("tat = %i", getIndex(array, "tat"));

PHP код:
stock getIndex(array[][], const value[], size = sizeof array)
{
new index;
for (new i = 0, j = strlen(value); i < j; i++)
{
index += value[i] + index;
}
index %= size;
return index;
}

Really nice and useful function but it is failing on multiple possibilities and on invalid checking (if the result is not in the array).
