PHP - Return results of comparison

August 27th, 2008 by Aaron

A useful reminder: you can make use of returning the results of comparisons for is*() functions. Let me explain that further…

PHP allows you to get the result of a comparison in a variable. Any variable you can return from a function. My my amazing transitive skills, I say you can return the comparison of a variable. Enough of this drivel - here’s an example:

1
2
3
4
5
6
7
8
function isGreaterThanFour($testVar)
{
  return $testVar > 4;
}
 
if (isGreaterThanFour(5)) {
  print 'yay!';
}

So - this is a very simple example, obviously - but it illustrates the powerful point of this functionality clearly.
