Help with PHP code

I am new to php and need help getting a program started. I need to figure a php code of a table of squares: The square of 1 is 1
The square of 2 is 4
The square of 3 is 9

Could someone help me get on track?

Thanks,
Cat

function sq($num)
{
return $num^2;
}


or just



for($i=0;$i<50;$i++)
{
echo "The square of $i is ". ($i^2) . "<br />";
}

I could not get this to work....:(
