What's the difference between this:

PHP Code:

stock strlower(string[])
{
    for(new i=0; string[i] != EOS; i++)
        string[i] = tolower(string[i]);
    return string;
} 


and this:

PHP Code:

strlower(string[])
{
    for(new i=0; string[i] != EOS; i++)
        string[i] = tolower(string[i]);
    return string;
} 


What does the stock do?

Also, should I use stock?
