How to merge this two specific arrays in PHP?

Question

I have this array:

$array['apples'][0]['name'] = 'Some apple';
$array['apples'][0]['price'] = 44;

$array['oranges'][0]['name'] = 'Some orange';
$array['oranges'][0]['price'] = 10;

How can I merge the two arrays so i get this:

$array[0]['name'] = 'Some apple';
$array[0]['price'] = 44;
$array[1]['name'] = 'Some orange';
$array[1]['price'] = 10;

Answer 1

$second_array = array();

foreach($array as $fruit => $arr){
    foreach($arr as $a){
     $second_array[] = array("name" => $a["name"], "price" => $a["price"]);
    }
}
print_r($second_array);

Since PHP 4 you can use

array_merge  ( array $array1  [, array $array2  [, array $...  ]] )

Example:

<?php
$beginning = 'foo';
$end = array(1 => 'bar');
$result = array_merge((array)$beginning, (array)$end);
print_r($result);
?>

The above example will output:

Array
(
    [0] => foo
    [1] => bar
)

Read more in the php manual: http://php.net/manual/en/function.array-merge.php

For multidimensional arrays (since PHP 4.0.1) you can use: array_merge_recursive ( array $array1 [, array $... ] )

Example:

<?php
$ar1 = array("color" => array("favorite" => "red"), 5);
$ar2 = array(10, "color" => array("favorite" => "green", "blue"));
$result = array_merge_recursive($ar1, $ar2);
print_r($result);
?>

The above example will output:

Array
(
    [color] => Array
        (
            [favorite] => Array
                (
                    [0] => red
                    [1] => green
                )

            [0] => blue
        )

    [0] => 5
    [1] => 10
)

I don't have PHP here to test, but isn't it just:

$array2 = $array['apples'];
array_merge($array2, $array['oranges']);

Granted, this is now in $array2 rather than $array...

Answer 4

It looks like the values of $array are the arrays that you want to merge. Since this requires a dynamic number of arguments passed to array_merge, the only way I know to accomplish it is through call_user_func_array:

$array = call_user_func_array('array_merge', array_values($array));

That should work with any amount of fruit.
