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.
