How can I merge array of arrays to one array in PHP?

give this a try 

$array = Array (0=>Array("choices"=>Array("choices_1"=>1,"choices_2" =>1)),

                         1 => Array ( "choices" => Array ( "choices_3" =>2))); 

$results = array_merge_recursive($array[0],$array[1]);

echo "<pre>";

print_r($results);

echo "</pre>";

You can use array_merge()

$result = array_merge($array1, $array2);

array_merge_recursive($array1, $array2);The above function will do your job. For full reference click

Here. Thanks.

$array = Array (

0=>Array(

"choices"=>Array("choices_1"=>1,"choices_2" =>1)

),

               1 => Array ( "choices" => Array ( "choices_3" =>2))

);

$result=array();

foreach($array as $arr){

 $result  = array_merge($arr['choices'],$result);

} 

You can use array_merge()

It is simple in use.

By using array_merge funtion

<?php

$array1 = array("color" => "red", 2, 4);

$array2 = array("a", "b", "color" => "green", "shape" => "trapezoid", 4);

$result = array_merge($array1, $array2);

print_r($result);

?>

use array_merge() function

You can use array_merge function to merge on one or more array to a single array. e.g

Suppose you have2 array array_1 and array_2.

result=array_merge(array_1,array_2).

the resulting array which is in my case is result will contain your all arrays.

<?PHP    $your_array=Array(Array('choices'=> Array('choices_1'=>1,'choices_2'=>1)),Array('choices' => Array('choices_3' =>2)));    $result = array_merge($your_array[0]['choices'], $your_array[1]['choices']);    var_dump($result);?>

array_merge is the way to go.
