How are you calling Reverse and what is it being passed?

PHP код:

Function:Reverse(string[])
{
         // Setting vars
    new string1[256];
               lengthOfString = strlen(string);
        // Processing 
    for(new i = 0; i < strlen(string); i++)
    {
        string1[i] = string[(lengthOfString-i)];
    }
        // Returning processed string
    return string1;
}
