Requirements

Laravel 9.x or later
PHP 8.0 or later

Installation

Fire up Composer and require this package in your project.

composer require laragear/comparable

That's it.

Usage

Add the Comparable trait to your object, and that's it. You can start a comparison using is() with the key name, unless you want to compare the whole object.

use Laragear\Compare\Comparable;

class Wallet
{
    use Comparable;
    
    // ...
}

Once done, you can start a comparison using is().

$wallet = new Wallet(['credits' => 1000]);

if ($wallet->is('credits')->aboveZero()) {
    return 'You have credits available, so go and spend some!';
}

return 'Your wallet is empty. Add some credits!';

When not issuing a key, the whole object will be used to compare.

Behind the scenes, it uses data_get() from Laravel helpers to retrieve the values from your object using "dot" notation.

if ($wallet->is('pending.total')->aboveZero()) {
    return "You have {$wallet->pending->total} pending.";
}

To negate a condition, just issue not(), or the not property.

if ($wallet->is('pending.total')->not->belowZero()) {
    return 'If you dont have credits, we can lend you some.';
}

Available conditions

`aboveZero()`

Checks if a numeric value is above zero.

if ($wallet->is('amount')->aboveZero()) {
    return 'You still have credits left.';
}

`belowZero()`

Checks if a numeric value is below zero.

if ($wallet->is('amount')->belowZero()) {
    return 'The Wallet is empty.';
}

`between()`

Check if the numeric value is between two numbers.

if ($product->is('weight')->between(10, 20)) {
    return 'This product can be picked up at the store.';
}

Issuing false as third parameter will make the comparison exclusive.

if ($product->is('weight')->between(10, 20, false)) {
    return 'The weight of the product is between 10.1 and 19.9 lbs.';
}

`blank()`

Check if the value is "blank".

if ($wallet->is('name')->blank()) {
    return 'Default Wallet';
}

`counting()`

Checks if a list contains the exact number of items.

if ($cart->is('items')->counting(10)) {
    return 'You are elegible for a discount for exactly 10 items.';
}

`containing()`

Checks if a string contains a string, or a list contains an item.

if ($product->is('name')->containing('discounted')) {
    return 'Discount are not applied to already discounted items.';
}

`containingOneItem()`

Check if the value is a list and contains only one item.

if ($cart->is('items')->containingOneItem()) {
    returns 'For free delivery, you need to add more than one item.';
}

`equalOrGreaterThan()`

Check that a numeric value, or the value list count, is equal or greater than a number.

if ($cart->is('items')->equalOrGreaterThan(10)) {
    return 'For more than 10 items, you will need to pick up them in the store.'
}

if ($cart->is('total')->equalOrGreaterThan(1000)) {
    return 'Your cart qualifies for free delivery';
}

`exactly()`

Check that a value is exactly the value given, strictly.

if ($product->is('name')->exactly('shoes')) {
    return 'Welp, these are shoes.';
}

`false()`

Check if a value is exactly false.

if ($product->is('can_deliver')->false()) {
    return 'The product cannot be delivered.';
}

`falsy()`

Check if a value evaluates to false.

if ($product->is('address')->false()) {
    return 'The product cannot be delivered without an address.';
}

`equalOrLessThan()`

Check that a numeric value, or the value list count, is equal or less than a number.

if ($cart->is('items')->equalOrLessThan(1)) {
    return 'Add more items to qualify for delivery.'
}

if ($cart->is('total')->equalOrLessThan(1000)) {
    return 'Your cart does not qualify for free delivery';
}

`filled()`

Check if the value is "filled".

if ($wallet->is('name')->blank()) {
    return 'Default Wallet';
}

`greaterThan()`

Check if the numeric value, or the list items count, is greater than the issued number,

if ($product->is('weight')->greaterThan(100)) {
    return 'This product is too heavy to be sent. You have to pick it up.';
}

`lessThan()`

Check if the numeric value, or the list items count, is less than the issued number,

if ($product->is('weight')->greaterThan(100)) {
    return 'This product is too heavy to be sent. You have to pick it up.';
}

if ($cary->is('items')->greaterThan(10)) {
    return 'We wil divide your order on multiple deliveries of 10 items';
}

`null()`

Check if the value is null.

if ($cart->is('promo_code')->null()) {
    return 'You can add a promo code to your code.';
}

`true()`

Check if a value is exactly true.

if ($product->is('can_deliver')->true()) {
    return 'The product can be delivered.';
}

`truthy()`

Check if a value evaluates to true.

if ($product->is('address')->true()) {
    return 'The products will be delivered to the issued address.';
}

`zero()`

Check if the numeric value, or the list items count, is exactly zero.

if ($cart->is('delivery_total')->zero()) {
    return 'This order has no cost of delivery. Enjoy!';
}

if ($cart->is('items')->zero()) {
    return 'Your cart is empty.';
}
