Merge multiple arrays from one array

Question

How to merge multiple arrays from a single array variable ? lets say i have this in one array variable

Those are in one variable ..
$array

Answer 1

This is the PHP equivalent of javascript Function#apply (generate an argument list from an array):

$result = call_user_func_array("array_merge", $input);

Answer 2

Since PHP 5.6 you can use variadics and argument unpacking.

$result = array_merge(...$input);

It's up to 3x times faster than call_user_func_array.

Answer 3

$arr1 = array(0=>1);
$arr2 = array(0=>2);

$merged = array_merge($arr1,$arr2);
print_r($merged);

Answer 4

$resultArray = array_merge ($array1, $array1);

$result = array();
foreach ($array1 as $subarray) {
    $result = array_merge($result, $subarray);
}

// Here it is done

Answer 5

This may work:

$array1 = array("item1" => "orange", "item2" => "apple", "item3" => "grape");
$array2 = array("key1" => "peach", "key2" => "apple", "key3" => "plumb");
$array3 = array("val1" => "lemon");

$newArray = array_merge($array1, $array2, $array3);

foreach ($newArray as $key => $value) {
  echo "$key - <strong>$value</strong> <br />"; 
}

Answer 6

array_merge can do the job

$array_meged = array_merge($a, $b);

after the comment

If fixed indexs you can use:

$array_meged = array_merge($a[0], $a[1]);

A more generic solution:

$array_meged=array();
  foreach($a as $child){
  $array_meged += $child;
}
