Installation

Step 1: Add package via composer

Add this package to your composer.json file with the following command

composer require mojopollo/laravel-helpers

Step 2: Update laravel 5.x config/app.php file

Add the following into the providers array:

Mojopollo\Helpers\StringHelperServiceProvider::class,
Mojopollo\Helpers\ArrayHelperServiceProvider::class,
Mojopollo\Helpers\DateTimeHelperServiceProvider::class,
Mojopollo\Helpers\FileHelperServiceProvider::class,

Add the following into the aliases array:

'StringHelper'   => Mojopollo\Helpers\Facades\StringHelper::class,
'ArrayHelper'    => Mojopollo\Helpers\Facades\ArrayHelper::class,
'DateTimeHelper' => Mojopollo\Helpers\Facades\DateTimeHelper::class,
'FileHelper'     => Mojopollo\Helpers\Facades\FileHelper::class,

Usage

To enable any of the helpers classes inside a controller, invoke the use keyword:

<?php namespace App\Http\Controllers;

use ArrayHelper;
use FileHelper;
...

You can now call any of helper methods via their facades:

StringHelper::replaceFirstMatch('one two three four five six', 3)

FileHelper::directoryFiles('/directory-path')

...

If you do not want to utilize the use keyword, you can alternatively use a blackslash\ when calling the helpers:

\StringHelper::replaceFirstMatch('one two three four five six', 3)

\FileHelper::directoryFiles('/directory-path')

...

StringHelper

camelCase

Convert a value to camel case

string camelCase(string $value)

StringHelper::camelCase('mojo_pollo');

// mojoPollo

snakeCase

Convert a value to snake case

string snakeCase(string $value [, string $delimiter = '_'])

StringHelper::snakeCase('mojoPollo');

// mojo_pollo

replaceFirstMatch

str_replace() for replacing just the first match in a string search

string replaceFirstMatch(string $search, string $replace, string $subject)

StringHelper::replaceFirstMatch('mojo', 'jojo', 'mojo is a pollo and mojo');

// jojo is a pollo and mojo

limitByWords

Returns a string limited by the word count specified

string limitByWords(string $str [, int $wordCount = 10])

StringHelper::limitByWords('one two three four five six', 3);

// one two three

ArrayHelper

random

Get a random element from the array supplied

mixed random(array $array)

ArrayHelper::random(['one', 'two', 'three']);

// two

morphKeys

Will camelize all keys found in a array or multi dimensional array

array morphKeys(array $originalArray [, $morphTo = 'camel'])

ArrayHelper::morphKeys([
  'user' => [
    'first_name' => 'mojo',
    'attributes' => [
      'second_key' => 'second value',
    ],
  ],
], 'camel');

// [
//   'user' => [
//     'firstName' => 'mojo',
//     'attributes' => [
//       'secondKey' => 'second value',
//     ],
//   ],
// ]

castValues

Will cast '123' as int, 'true' as the boolean true, etc

array castValues(array $originalArray)

ArrayHelper::castValues([
  'value1' => 'true',
  'value2' => 'false',
  'value3' => '123',
  'value4' => '{"mojo": "pollo"}',
]);

// [
//   'value1' => true,
//   'value2' => false,
//   'value3' => 123,
//   'value4' => ['mojo' => 'pollo'],
// ]

sortByPriority

Re-orders an array by moving elements to the top of the array based on a pre-defined array stating which elements to move to top of array. Note: when $strictMatch is set to false, the match will not take into account type and case sensitivity

array sortByPriority(array $originalArray, array $priority [, $strictMatch = true])

$originalArray = [
  [
    'name' => 'White Castle',
    'city' => 'Las Vegas',
    'zip' => '89109',
  ],
  [
    'name' => 'Burger Town',
    'city' => 'Sherman Oaks',
    'zip' => '91403',
  ],
  [
    'name' => 'Krabby Patty',
    'city' => 'Walking the Plankton',
    'zip' => '00000',
  ],
  [
    'name' => 'Uber Burger',
    'city' => 'Little Rock',
    'zip' => '72201',
  ],
];

$priority = [
  [
    'city' => 'Walking the Plankton'
  ],
  [
    'name' => 'Burger Town'
  ],
];


ArrayHelper::sortByPriority($originalArray, $priority);

// [
//   [
//     'name' => 'Krabby Patty',
//     'city' => 'Walking the Plankton',
//     'zip' => '00000',
//   ],
//   [
//     'name' => 'Burger Town',
//     'city' => 'Sherman Oaks',
//     'zip' => '91403',
//   ],
//   [
//     'name' => 'White Castle',
//     'city' => 'Las Vegas',
//     'zip' => '89109',
//   ],
//   [
//     'name' => 'Uber Burger',
