How to change name of keys of a multidimensional array

Question

I have two arrays one of them contain a new key name

$assoc = ['name', 'lastname', 'pesel']; 

and second look this

$inputs = ['John', 'Don', '987987', 'Mike', 'Evans', '89779' ];

Array $assoc is the new key name, and I would like to change [0],[1] to ['name'] etc

array(2) {
 ['person'] =>
 array(3) {
 ['name'] => string(4) "John"
 ['lastname'] => string(3) "Don"
 ['pesel'] => string(6) "987987"
 }
 ['person'] =>
 array(3) {
 ['name'] => string(4) "Mike"
 ['lastname'] => string(5) "Evans"
 ['pesel'] => string(5) "89779"
 }
}

Thanks for your help

• mario: Use array_chunk on your value list, then bind keys to each chunk using array_combine.
• Decent Dabbler: You can't have multiple elements in one array that have the same key. The latter will overwrite the former. So array( 'person' => ..., 'person' => ... ) will not be an array with two elements.
• konadrian: yes you have right :) i'm so stupid

Answer 1

It's pretty simple:

$new_array = array();
foreach(array_chunk($inputs, 3) as $person) {
 $new_array[] = array_combine($assoc, $person);
}

Answer 2

<?php
$assoc=Array("name", "lastname", "pesel");
$inputs=Array('John', 'Don', '987987', 'Mike', 'Evans', '89779' );
$resultant_array=Array();
for($i=0; $i<count($inputs); $i+=count($assoc)){
//echo $i."\n\n";
 for($j=0; $j<count($assoc); $j++){
 $b2g[$assoc[$j]]=$inputs[$i+$j];
 }
 $resultant_array[]=$b2g;
} 
print_r($resultant_array);

It is a more lengthy and general purpose use.. I actually have used much recurssions..

• silkfire: Weird that you preferred this answer to mine... I assume you like things cluttery.
• Ronnie: No. I like exploring with code rather looking for it on Google.. both takes same time
