Combine 2 PHP array into multidimensional

Question

I have 2 separated arrays:

Array
(
    [0] => Header 1
    [1] => Header 2
)

Array
(
    [0] => Array
        (
            [0] => Content #1
            [1] => Content #2
        )

    [1] => Array
        (
            [0] => Content #1.1
        )

)

How to combine those 2 arrays into multidimensional with a format like this below:

Array
(
    [0] => Array
        (
            [Header 1] => Content #1
            [Header 2] => Content #1.1
        )

    [1] => Array
        (
            [Header 1] => Content #2
        )

)

The purpose is to create HTML table. I found a way to create a table from here How to create a HTML Table from a PHP array? but the array format should be like the last one.

If you want to learn something you should modify the recipe you found to match the input data you have, not the other way around. — axiac

A straight forward way using foreach loops...

$arr1 = ['Header 1', 'Header 2'];
$arr2 = [['Content #1', 'Content #2'],
    [ 'Content #1.1']];

$result= [];
foreach ( $arr2 as $arr3 ){
    $partial = [];
    foreach ( $arr3 as $key=>$value )  {
        $partial[$arr1[$key]] = $value;
    }
    $result[] = $partial;
}

print_r($result);

(Pleas excuse the not very inventive variable names)

gives...

Array
(
    [0] => Array
        (
            [Header 1] => Content #1
            [Header 2] => Content #2
        )

    [1] => Array
        (
            [Header 1] => Content #1.1
        )

)

It could be simplified if you knew that the second array always had the same number of values as the first array as you could use array_combine() in the loop instead. Although you could fudge this...

$arr1 = ['Header 1', 'Header 2'];
$arr2 = [['Content #1', 'Content #2'],
    [ 'Content #1.1']];

$result= [];
foreach ( $arr2 as $arr3 ){
    $arr4 = array_slice($arr1,0,count($arr3));
    $result[] = array_combine($arr4, $arr3);
}

print_r($result);

I guess you should use the "+" operator i.e $newArray = $array1 +array2

Have you tried? It doesn't do anything near the expected outcome.

Here is your solution

Input

$array1 = array('Header 1','Header 2');
$array2 = array(array('Content #1','Content #2'),array('Content #1.1'));

Solution

$new = array();
foreach($array2 as $key => $row){
    for($i=1;$i<=count($row);$i++){
    $new[$key]['Header '.$i] = $row[$i-1];
    }
}

Output

Array
(
    [0] => Array
        (
            [Header 1] => Content #1
            [Header 2] => Content #2
        )

    [1] => Array
        (
            [Header 1] => Content #1.1
        )

)
