Help with writing some PHP code..?
Hello, I am no programmer, my friend needed some help!!!

Write a PHP function called isPositive that takes one parameter that represents an integer and returns true when the integer is positive and false when the integer is negative. By the way, 0 is a positive number.

Test your function by calling it with 0, -1 and 1 as parameters.

I need a function that is able to do this: http://citstudent.lanecc.edu/~davidb111/quiz1/1.php
