And yes, I know this is simple to almost a silly level. But it's something that I found myself adding to a bunch of different PHP projects so it seemed like a perfect bit of code to build into a package.

Installation

Install using composer

composer require aelora/truthy

There are no settings.

Usage

Once loaded, there will be an isTruthy and isFalsy function in the global namespace.

The following values are considered falsy

false
null
empty string
0
0.0
empty array
empty object
strings "no", "n", "false", "f", "off", "null", "0", "0.0"

Everything else is considered truthy.

if (isTruthy($value)) {
    // Do something
} 
if (isFalsy($value)) {
    // Do something
}

Tests

composer test
