To infinity and beyond! Working with infinity in PHP

We can file this one under the “PHP functions I never knew existed and probably
will never use” category. Seems that as of PHP 4.2.0 and beyond there was the
inclusion of an is_finite() and an is_infinite() function. The names are
pretty self explanatory and I’m sure there are some smart kids out there that
would use these (although I’d expect them to be working in a different language

The usage is pretty simple, pass the function a value and it will return either
boolean true or false:

$value = log(0 // This is infinite


Comment below if you’ve used this function before in the real world, dying to
hear about it!
