PHP: combine several arrays in associative one - php

Question

I have this arrays:
$main = array("Name","Age");
$fname =array("Peter","Ben","Joe");
$age = array("35","37","43");
I need to combine it. Output array must be:
[0] =>
[Name] => [Peter]
[Age] => [35]
[1] =>
[Name] => [Ben]
[Age] => [37]
[2] =>
[Name] => [Joe]
[Age] => [43]
And so on. I have tried array_combine, but it gives an error, cuz $main contains only two values, array_merge combine arrays not exactly i want, it adds any next array to the end of result array.
How to solve my issue? Help , please!

Answer 1

Something like this should do:
$result = array_map(
function () use ($main) {
return array_combine($main, func_get_args());
},
$fname,
$age
);
PHP 5.6+ allows this nicer syntax for the callback:
function (...$vals) use ($main) {
return array_combine($main, $vals);
}
Though I would first point out that this is a rather peculiar dataset to end up with, and you should maybe see if there's something you can do before this to get your data in better shape so you don't need to bend over backwards like this in the first place.

The solution using array_map and array_combine functions:
$result = array_map(function($v) use($main){
return array_combine($main, $v);
}, array_map(null, $fname, $age));
print_r($result);
The same can be achieved with regular foreach loop + array_combine function:
$result = [];
foreach ($fname as $k => $v) {
$result[] = array_combine($main, [$v, $age[$k]]);
}
The output:
Array
(
[0] => Array
(
[Name] => Peter
[Age] => 35
)
[1] => Array
(
[Name] => Ben
[Age] => 37
)
[2] => Array
(
[Name] => Joe
[Age] => 43
)
)

Answer 3

this is what you want :
$newArray = [];
$main = array("Name","Age");
$fname =array("Peter","Ben","Joe");
$age = array("35","37","43");
$newArray = array_combine($fname, $age);
$array = [];
foreach($newArray as $key => $value) {
$array[] = [
$main[0] => $key,
$main[1] => $value
];
}
var_dump($array);
