PHP code help

[SpikedUDE]

Please write a PHP function using valid syntax. The function should be named "squared" and it should accept one parameter, called "$number". The function should first check if the parameter is a numeric value (an integer or floating point number, or a string containing a number). If not, it should return the boolean False. If it is numeric, it should return a value equal to the number sqared (the number times itself).

 

If anyone can help will appreciate it vey much!!! Thanks guys!!

This doesn't check if there is a number in the string.

What you'd need to do for that is.. remove all the letters, leaving only numbers.. and then go through with the is_numeric() section.

 

function myfunc($number) {
    if (is_numeric($number)) {
        $number = $number * $number;
        return $number;
    } else {
       return false;
    }
}

This looks like an assignment to me. It's VERY easy. I'm sure if you just read the manual on functions you could do this yourself
