    Squaring with PHP

    How can I square using PHP? i.e. 2^2 = 4 and 4^2 = 16.

    I've looked but can't find it in the manual anywhere.

    Thanks......

    I don't want the square root. I want to square the number.

    Exponentiation doesn't use ^ or ** as you might be used to with other languages. To calculate "z equals y to the x" use:

    $z = pow(y,x)
