A method of combining multiple one-dimensional combinations of PHP into two-dimensional arrays

In the development process, you need to collate the data, where more than one operation is to consolidate the various data into a set of data. This article provides a way to combine multiple one-dimensional combinations into two-dimensional arrays, providing complete code and demonstrations.

The code of the combined method is as follows, because the function variable parameter needs to be used, so PHP version 5.6 above.

<?php/** * Combine multiple one-dimensional combinations into two-dimensional arrays * * @param array  $keys define the key values of the new two-dimensional array, each corresponding to a one-dimensional array * @param  array $args Multiple one-dimensional array of arrays * @return Array */function array_merge_more ($keys, ... $arrs) {    //Check if the parameter is correct    if (! $keys | |!is_array ($keys) | |! $arrs | |!is_ Array ($arrs) | | Count ($keys)!=count ($arrs)) {        return array ();    }    The maximum length of a one-dimensional array    $max _len = 0;    Organize the data to re-index all one-dimensional arrays    for ($i =0, $len =count ($arrs), $i < $len, $i + +) {        $arrs [$i] = Array_values ($arrs [$i]);        if (count ($arrs [$i]) > $max _len) {            $max _len = count ($arrs [$i]);        }    }    Combined data    $result = Array ();    for ($i =0; $i < $max _len; $i + +) {        $tmp = array ();        foreach ($keys as $k = + $v) {            if (isset ($arrs [$k] [$i]) {                $tmp [$v] = $arrs [$k] [$i];            }        }        $result [] = $tmp;    }    return $result;}? >

1. Combine multiple one-dimensional numbers into two-dimensional arrays

<?PHP$ARR1 = Array (' Fdipzone ', ' Terry ', ' Alex '), $arr 2 = array (+), $arr 3 = array (' Programmer ', ' designer ', ' test Er '); $keys = Array (' name ', ' age ', ' profession '); $result = Array_merge_more ($keys, $arr 1, $arr 2, $arr 3);p Rint_r ($result) ;? >

Output:

Array (    [0] = = Array        (            [name] = Fdipzone            [age] [            profession] = programmer        ) C7/>[1] = Array        (            [name] + Terry            [age] =            [profession]        = designer)    [2] = > Array        (            [name] + Alex            [age] [            profession] = tester        ))

2. Multiple two-dimensional array extraction partial data is combined into a two-dimensional array

<?PHP$ARR1 = Array (' name ' = '    fdipzone '), Array (    ' name ' = = ' Terry '),    Array (' name ' = = ') Alex '), $arr 2 = Array (' Age ' =>18), Array (' Age '    =>19),    Array (' age ' =>20), $arr 3 = Array ( Array ('    profession ' = ' programmer '),    array (' profession ' = ' designer '),    array (' profession ' = ' tester '); $arr 1 = array_column ($arr 1, ' name '), $arr 2 = Array_column ($arr 2, ' age '); $arr 3 = Array_column ($arr 3, ' Profession '); $keys = Array (' name ', ' age ', ' profession '); $result = Array_merge_more ($keys, $arr 1, $arr 2, $arr 3);p Rint_r ( $result);? >

Output:

Array (    [0] = = Array        (            [name] = Fdipzone            [age] [            profession] = programmer        ) C6/>[1] = Array        (            [name] + Terry            [age] =            [profession] = designer        )    [2] =& Gt Array        (            [name] + Alex            [age] =            [profession] = tester        ))
