How to Create Helpers in Laravel

In this tutorial we are going to learn about global functions in Laravel.

Step 1 :  In the first step we need to create a Helpers.php file in app folder.

app\Helpers.php

<?php
 
function getSortName($name = null)
{
    $a = explode(' ', $name);
    if (count($a) > 0) {
        $b = substr($a[0], 0, 1);
        if (isset($a[1]) && trim($a[1])) {
            $b .= substr($a[1], 0, 1);
        }
        return $b;
    } else {
        return substr(str_shuffle('ABCDFGHIJKLMNOPQRSTUVWXYZ'), 0, 1);
    }
}

Step 2 :  Add Helpers.php file path in composer.json

Add this code in composer.json file.

composer.json

"files": [
    "app/Helpers.php"
 ]

Step 3: Run Command

In the last step, run the following command.

composer dump-autoload

Now custom hepler is created in your Laravel aap.

let's see example of the created helper function.

Example -

<h2>{{ getSortName('John Doe') }} - John Doe</h2>
<h2>{{ getSortName('Denzel Washington') }} - Denzel Washington</h2>

Output

JD - John Doe

DW - Denzel Washington
