如何合并这个数组的PHP

Question

This is my first array var_dump

array(1) {
  [0]=>
  array(55) {
    ["Primary Maths"]=>
    NULL
    ["Primary Environment"]=>
    NULL
    ["Primary English"]=>
    NULL
    ["Primary Sinhala"]=>..........etc

In first array contain 55 array elements. .

This is my second array var_dump

array(1) {
  [0]=>
  array(660) {
    ["Primary_MathsJAN"]=>
    string(7) "checked"
    ["Primary_MathsFEB"]=>
    string(7) "checked"
    ["Primary_MathsMAR"]=>
    string(7) "checked" ...etc

In first array contain 660 array elements. .

So i want to merge(JOIN) first array with second array.But i want it like this.I want to join first array one value with second array 12 values...

1st array elements(55) * 12 = 2nd array elements(660)

Is there anyway to do this ?

Answer 1

There might be some combination of built in functions you could use, but every time I find myself in a situation like this I'd rather just write 2 loops and be done with it. In case you decide to follow my example what you can do is foreach the first array and then use a regular for with 12 loops for the second array within the foreach. You might also want to use array_values on the second array in order to save yourself the trouble of fighting keys.

Best wishes and good luck!

Answer 2

This will split the 2nd array into an multidimentional array into 12 element chunks, and combine it with the first array. However, it looks like you need to use the keys from the 1st array, so I added the function array_keys:

array_combine(array_keys($a1), array_chunk($a2, 12))

Answer 3

If I have well understand the question, this will do the job:

$result = $array1[0];
$temp = array_chunk($array2[0],12);
foreach ($result as &$value) {
    $value = array_shift($temp)
}
