🦑12 Best Laravel Helpers To Consider Using :

Laravel comes with a ton of useful global helper functions. If you haven’t used them so far, this is the best time to start. Over the years of me using the Laravel, 10 of those emerged as the most useful, making the development a lot easier. Sometimes we don’t really see how we can apply some methods until we see an example. So let’s get down to it and see the top 10 helpers I often use the most.

1)) array_flatten()
The array_flatten function flattens a multi-dimensional array into a single level array:

$array = ['name' => 'John', 'tools' => ['Laravel', 'Recipes']];

$flattened = array_flatten($array);

// ['John', 'Laravel', 'Recipes']
It is really helpful if I need to collect all the array values where some values might contain another array. Here, I am just concentrated on getting a new array with a list of all the values. It works like a charm!

2)) array_forget()
The array_forget function removes a given key / value pair from a deeply nested array using “dot” notation:

$array = ['users' => ['managers' => ['name' => 'John']]];

array_forget($array, 'users.managers');

// ['users' => []]
This is a nicer version of unset() function which is a native PHP function for removing array elements.

3)) array_get()
Another amazing method that makes your development life easier. The array_get function retrieves a value from a deeply nested array using “dot” notation:

$array = ['users' => ['managers' => ['name' => 'John']]];

$price = array_get($array, 'products.desk.price');

// 100
The array_get function also accepts a default value, which will be returned if the specific key is not found:

$discount = array_get($array, 'users.managers.missing', 'Jane');

// Jane

If there is anything more valuable than getting a deeply nested value withing an array, that’s an ability to set a default value.

4)) array_only()
Imagine you had a lot of keys inside your array that you don’t want to use. As a matter of fact, out of 10 keys, you only want to use two and instantly create a new array. Instead of going through and array_forget()each item, you could simply pick the ones you want. The array_only function returns only the specified key / value pairs from the given array:

$array = ['name' => 'John', 'type' => 'user', 'age' => 44];

$slice = array_only($array, ['name', 'age']);

// ['name' => 'John', 'age' => 44]

5)) array_prepend()
How often have you used array_push and had to reverse the array instead of pre-pending it. The array_prepend function will push an item onto the beginning of an array:

$array = ['one', 'two', 'three', 'four'];

$array = array_prepend($array, 'zero');

// ['zero', 'one', 'two', 'three', 'four']
It’s great that it works for key/value as well. If needed, you may specify the key that should be used for the value:

$array = ['price' => 100];

$array = array_prepend($array, 'Desk', 'name');

// ['name' => 'Desk', 'price' => 100]

6)) array_sort_recursive()
Many times you would get nested arrays that you might need to sort all at the same time. Yes, you could write a simple function to loop through and sort each array, but why, when you have the following function. The array_sort_recursive function recursively sorts an array using the sort function:

$array = [
['Roman', 'Taylor', 'Li'],
['PHP', 'Ruby', 'JavaScript'],
];

$sorted = array_sort_recursive($array);

/*
[
['Li', 'Roman', 'Taylor'],
['JavaScript', 'PHP', 'Ruby'],
]
*/
7)) array_wrap()
Sometimes you want to turn your single, string result into an array with only one element. Being able to reduce code to one line is always good. The array_wrap function wraps the given value in an array. If the given value is already an array it will not be changed:

$string = 'Success';

$array = array_wrap($string);

// ['Success']
If the given value is null, an empty array will be returned:

$nothing = null;

$array = array_wrap($nothing);

// []
