Outline
Installation
Composer Install
# composer require marsapp/arrayhelper
Include
Include composer autoloader before use.
require __PATH__ . "vendor/autoload.php";
Usage
Example
Namespace use:
// Use namespace use marsapp\helper\myarray\ArrayHelper; // Data $data = [ ['c_sn' => 'a110', 'u_sn' => 'b1', 'u_no' => 'a001', 'u_name' => 'name1'], ['c_sn' => 'a110', 'u_sn' => 'b2', 'u_no' => 'b012', 'u_name' => 'name2'], ]; // Index by ArrayHelper::indexBy($data, ['c_sn', 'u_no']); // Get name by a110 => a001 => u_name $name = ArrayHelper::getContent($data, 'a110, a001, u_name'); // $name = name1;
API Reference
indexBy()
Data re-index by keys
indexBy(Array & $data, Array|String $keys, Bool $obj2array = false) : array
Since $data is a reference, $data will change after indexBy() is executed.
Since $data is a reference, the return is useless.
If you want to keep $data, you can clone it before using it.
Example :
$data = [ ['c_sn' => 'a110', 'u_sn' => 'b1', 'u_no' => 'a001', 'u_name' => 'name1'], ['c_sn' => 'a110', 'u_sn' => 'b2', 'u_no' => 'b012', 'u_name' => 'name2'], ]; ArrayHelper::indexBy($data, ['c_sn','u_sn','u_no']); // $data = [ // 'a110' => [ // 'b1' => ['a001' => ['c_sn' => 'a110', 'u_sn' => 'b1', 'u_no' => 'a001', 'u_name' => 'name1']], // 'b2' => ['b012' => ['c_sn' => 'a110', 'u_sn' => 'b2', 'u_no' => 'b012', 'u_name' => 'name2']], // ], // ];
groupBy()
Data re-index and Group by keys
groupBy(Array & $data, Array|String $keys, Bool $obj2array = false) : array
Since $data is a reference, $data will change after indexBy() is executed.
Since $data is a reference, the return is useless.
If you want to keep $data, you can clone it before using it.
Example :
$data = [ ['c_sn' => 'a110', 'u_sn' => 'b1', 'u_no' => 'a001', 'u_name' => 'name1'], ['c_sn' => 'a110', 'u_sn' => 'b2', 'u_no' => 'b012', 'u_name' => 'name2'], ['c_sn' => 'a110', 'u_sn' => 'b2', 'u_no' => 'b012', 'u_name' => 'user name 3'], ]; ArrayHelper::groupBy($data, ['c_sn','u_sn','u_no']);
$data reqult:
[ 'a110' => [ 'b1' => ['a001' => [ 0 => ['c_sn' => 'a110', 'u_sn' => 'b1', 'u_no' => 'a001', 'u_name' => 'name1'] ] ], 'b2' => ['b012' => [ 0 => ['c_sn' => 'a110', 'u_sn' => 'b2', 'u_no' => 'b012', 'u_name' => 'name2'], 1 => ['c_sn' => 'a110', 'u_sn' => 'b2', 'u_no' => 'b012', 'u_name' => 'user name 3'] ] ], ], ];
indexOnly()
Data re-index by keys, No Data
indexOnly(Array & $data, Array|String $keys, Bool $obj2array = false) : array
Since $data is a reference, $data will change after indexBy() is executed.
Since $data is a reference, the return is useless.
If you want to keep $data, you can clone it before using it.
Example :
$data = [ ['c_sn' => 'a110', 'u_sn' => 'b1', 'u_no' => 'a001', 'u_name' => 'name1'], ['c_sn' => 'a110', 'u_sn' => 'b2', 'u_no' => 'b012', 'u_name' => 'name2'], ]; ArrayHelper::indexOnly($data, ['c_sn','u_sn','u_no']);
$data reqult:
[ 'a110' => [ 'b1' => [ 'a001' => '' ], 'b2' => [ 'b012' => '' ], ], ];
getContent()
Get Data content by index
getContent(Array $data, Array|String $indexTo = [], Bool $exception = false) : array|mixed
Example:
$data = ['user' => ['name' => 'Mars', 'birthday' => '2000-01-01']]; // No indexTo, get all $output = ArrayHelper::getContent($data); // $output: ['user' => ['name' => 'Mars', 'birthday' => '2000-01-01']]; // Target is array $output = ArrayHelper::getContent($data, 'user'); $output = ArrayHelper::getContent($data, ['user']); // $output: ['name' => 'Mars', 'birthday' => '2000-01-01']; // Target is string $output = ArrayHelper::getContent($data, 'user, name'); $output = ArrayHelper::getContent($data, ['user', 'name']); // $outpu: Mars // No target $output = ArrayHelper::getContent($data, 'user, name, aaa'); $output = ArrayHelper::getContent($data, ['user', 'name', 'aaa']); // $outpu: []
getFallContent()
Get fall point content
- Get the data in an ordered non-contiguous index array
- If there is no fall point, return null.
- Ensure performance by sorting $data ahead of time:
- a. Sorting $data (ASC)
- b. Close $sortOut
- c. Use function ArrayHelper::getFallContent()
getFallContent(Array $data, $referKey, $sortOut = 'default') : mixed
Parameters
- $data: The array to compare from. array
- $referKey: Refer key to compare against. string
- $sortOut: Whether the input needs to be rearranged. Value: true, false, 'default'. If it is 'default', see getSortOut()
Return Values
- Returns the resulting mixed.
Example :
$data = ['2019-05-01' => '20', '2019-06-01' => '30', '2019-06-15' => '50']; $value = ArrayHelper::getFallContent($data, '2019-06-11', false); // $value = 30;
gather()
Data gather by list
Collect and classify target data according to the list of fields
gather(Array $data, Array $colNameList, Int $objLv = 1) : array
Example Data :
$data = [ 0 => ['sn' => '1785','m_sn' => '40','d_sn' => '751','r_type' => 'staff','manager' => '1','s_manager' => '1','c_user' => '506'], 1 => ['sn' => '1371','m_sn' => '40','d_sn' => '583','r_type' => 'staff','manager' => '61','s_manager' => '0','c_user' => '118'], 2 => ['sn' => '1373','m_sn' => '40','d_sn' => '584','r_type' => 'staff','manager' => '61','s_manager' => '0','c_user' => '118'], 3 => ['sn' => '7855','m_sn' => '40','d_sn' => '2303','r_type' => 'staff','manager' => '71','s_manager' => '0','c_user' => '61'], 4 => ['sn' => '7856','m_sn' => '40','d_sn' => '2304','r_type' => 'staff','manager' => '75','s_manager' => '0','c_user' => '61'] ];
Example 1 :
Field
manager
,s_manager
,c_user values
are placed in the same one-dimensional array
$ssnList1 = ArrayHelper::gather($data, array('manager', 's_manager','c_user'), 1);
$ssnList1 reqult:
[1 => '1',506 => '506',61 => '61',0 => '0',118 => '118',71 => '71',75 => '75'];
Example 2 :
The field
manager
is placed in an array, the fieldss_manager
, and thec_user
values are placed in the same array. Form a 2-dimensional array
$ssnList2 = ArrayHelper::gather($data, array('manager' => array('manager'), 'other' => array('s_manager','c_user')), 1);
$ssnList2 reqult:
[ 'manager' => [1 => '1',61 => '61',71 => '71',75 => '75'], 'other' => [1 => '1',506 => '506',0 => '0',118 => '118',61 => '61'] ];
diffRecursive()
Array Deff Recursive
Compare $srcArray with $contrast and display it if something on $srcArray is not on $contrast.
diffRecursive(Array $srcArray, $contrast) : array
Example :
$data1 = [ 0 => ['c_sn' => 'a110', 'u_sn' => 'b1', 'u_no' => 'a001', 'u_name' => 'name1'], 1 => ['c_sn' => 'a110', 'u_sn' => 'b2', 'u_no' => 'b012', 'u_name' => 'name2'], 2 => ['c_sn' => 'a110', 'u_sn' => null, 'u_no' => 'c024', 'u_name' => 'name3'], ]; $data2 = [ 0 => ['c_sn' => 'a110', 'u_sn' => 'b1', 'u_no' => 'a001', 'u_name' => 'name1'], 1 => ['c_sn' => 'a110', 'u_sn' => 'b2', 'u_no' => 'b012', 'u_name' => 'name2222'], 2 => ['c_sn' => 'a110', 'u_sn' => 'b2', 'u_no' => 'c024', 'u_name' => 'user name 3'], ]; $diff = ArrayHelper::diffRecursive($data1, $data2);
$diff result :
[ 1 => ['u_name' => 'name2'], 2 => ['u_sn' => NULL,'u_name' => 'name3'] ];
sortRecursive()
Array Sort Recursive
sortRecursive(Array & $srcArray, $type = 'ksort') : void
$srcArray is a reference
$type : ksort(default), krsort, sort, rsort
Example :
$data1 = [ 'b1' => [ 0 => ['c_sn' => 'a110', 'u_sn' => 'b1', 'u_no' => 'a001', 'u_name' => 'name1'] ], 'b2' => [ 0 => ['c_sn' => 'a110', 'u_sn' => 'b2', 'u_no' => 'b012', 'u_name' => 'name2'], 1 => ['c_sn' => 'a110', 'u_sn' => 'b2', 'u_no' => 'b012', 'u_name' => 'user name 3'] ], ]; $data2 = $data1; ArrayHelper::sortRecursive($data1, 'ksort'); ArrayHelper::sortRecursive($data2, 'krsort');
$data1 result:
[ 'b1' => [ 0 => ['c_sn' => 'a110','u_name' => 'name1','u_no' => 'a001','u_sn' => 'b1'] ], 'b2' => [ 0 => ['c_sn' => 'a110','u_name' => 'name2','u_no' => 'b012','u_sn' => 'b2'], 1 => ['c_sn' => 'a110','u_name' => 'user name 3','u_no' => 'b012','u_sn' => 'b2'] ] ];
$data2 result:
[ 'b2' => [ 1 => ['u_sn' => 'b2','u_no' => 'b012','u_name' => 'user name 3','c_sn' => 'a110'], 0 => ['u_sn' => 'b2','u_no' => 'b012','u_name' => 'name2','c_sn' => 'a110'] ], 'b1' => [ 0 => ['u_sn' => 'b1','u_no' => 'a001','u_name' => 'name1','c_sn' => 'a110'] ] ];
