Introduction

CSE HELPERS is a collection of several libraries with simple functions written in PHP for people.

Despite using PHP as the main programming language for the Internet, its functions are not enough. ARRAY CSE HELPERS provides extra static methods allowing you to deal with arrays more efficiently.

CSE HELPERS was created for the rapid development of web applications.

CSE Helpers project:

• Array CSE helpers
• Cookie CSE helpers
• Date CSE helpers
• Email CSE helpers
• IP CSE helpers
• Json CSE helpers
• Math Converter CSE helpers
• Phone CSE helpers
• Request CSE helpers
• Session CSE helpers
• Word CSE helpers

Below you will find some information on how to init library and perform common commands.

Usage

The class consists of static methods that are conveniently used in any project. See example examples-arrays.php.

GET array data by key

Example:

Arrays::get([
    'key1' => 'value1',
    'key2' => 'value2',
    'key3' => 'value3'
], 'key1');
// value1

Set default value for not exist key:

Arrays::get([
    'key1' => 'value1',
    'key2' => 'value2',
    'key3' => 'value3'
], 'key4', 'default1');
// default1

Pull array key

Example:

Arrays::pullKey([
    'key1' => 'value1',
    'key2' => 'value2',
    'key3' => 'value3'
], 'key1');
// value1
/**
* [
*     'key2' => 'value2',
*     'key3' => 'value3'
* ]
*/

Set default value for not exist key:

Arrays::pullKey([
    'key1' => 'value1',
    'key2' => 'value2',
    'key3' => 'value3'
], 'key4', 'default1');
// default1

Convert OBJECT TO ARRAY

Example:

$object = new \stdClass();
$object->key1 = 'value1';
$object->key2 = 'value2';
Arrays::objectToArray($object);
/**
* [
*     'key1' => 'value1',
*     'key2' => 'value2'
* ]
*/

Convert array TO html TAG

Example:

Arrays::toTags([
    'tag1' => [
        1,
        'attr1' => 1,
        'attr2' => 2
    ],
    'tag2' => 2,
    'tag3'
]);
// <tag1 attr1="1" attr2="2">1</tag1><tag2>2</tag2><tag3 />

Convert array to MAP

Data:

$array = [
    [
        'keyGroup1' => 'value1',
        'keyGroup2' => 'value2',
        'keyGroup3' => 'value3'
    ], [
        'keyGroup2' => 'value2',
        'keyGroup3' => 'value3'
    ], [
        'keyGroup1' => 'value1',
        'keyGroup3' => 'value2'
    ]
];

Example:

Arrays::map($array, 'keyGroup1');
/**
* [
*     'value1' => [
*           'keyGroup1' => 'value1',
*           'keyGroup3' => 'value2'
*     ]
* ]
*/

Change key group:

Arrays::map($array, 'keyGroup2');
/**
* [
*     'value2' => [
*           'keyGroup2' => 'value2',
*           'keyGroup3' => 'value3'
*     ]
* ]
*/

Set key value:

Arrays::map($array, 'keyGroup3', 'keyGroup1');
/**
* [
*     'value3' => null,
*     'value2' => 'value1'
* ]
*/

Array GROUP

Data:

$array = [
    [
        'keyGroup1' => 'value1',
        'keyGroup2' => 'value2',
        'keyGroup3' => 'value3'
    ], [
        'keyGroup2' => 'value2',
        'keyGroup3' => 'value3'
    ], [
        'keyGroup1' => 'value1',
        'keyGroup3' => 'value2'
    ]
];

Example:

Arrays::group($array, 'keyGroup1');
/**
* [
*     'value1' => [
*         [
*             'keyGroup1' => 'value1',
*             'keyGroup2' => 'value2',
*             'keyGroup3' => 'value3'
*         ], [
*             'keyGroup1' => 'value1',
*             'keyGroup3' => 'value2'
*         ]
*     ]
* ]
*/

Change key group:

Arrays::group($array, 'keyGroup2');
/**
* [
*     'value1' => [
*         [
*             'keyGroup1' => 'value1',
*             'keyGroup2' => 'value2',
*             'keyGroup3' => 'value3'
*         ], [
*             'keyGroup2' => 'value2',
*             'keyGroup3' => 'value3'
*         ]
*     ]
* ]
*/

Set key value:

Arrays::group($array, 'keyGroup3', 'keyGroup1');
/**
* [
*     'value3' => [
*         [
*             'value1',
*             null
*         ]
*     ],
*     'value2' => [
*         [
*             'value1'
*         ]
*     ],
* ]
*/
