How to replace array keys with another array values - php

Question

I have two arrays and I want to replace the second array keys with the first array values if both keys matches.
As an example: Replace A with Code And B with name
How to do this;
<?php
$array = array('A' => 'code', 'B' =>'name');
$replacement_keys = array
(
array("A"=>'sara','B'=>2020),
array("A"=>'ahmed','B'=>1010)
);
foreach($replacement_keys as $key => $value){
foreach($value as $sk => $sv){
foreach($array as $rk => $rv){
if($sk == $rk ){
$sk = $rv;
}
}
}
}
echo "<pre>";
print_r($value);
echo "</pre>";
exit;
I want the result to be like this
array(
[0] => Array
(
[name] => ahmed
[code] => 1020
)
[1] => Array
(
[name] => sara
[code] => 2020
)
)

Answer 1

<?php
$array = array('A' => 'code', 'B' =>'name');
$replacement_keys = array
(
array("A"=>'sara','B'=>2020),
array("A"=>'ahmed','B'=>1010)
);
foreach($replacement_keys as &$value)
{
foreach ($array as $key => $name) {
$value[$name] = $value[$key];
unset($value[$key]);
}
}
var_dump($replacement_keys);

Answer 2

Try this:
<?php
$array = array('A' => 'code', 'B' =>'name');
$replacement_keys = array
(
array("A"=>'sara','B'=>2020),
array("A"=>'ahmed','B'=>1010)
);
$newArray = array();
foreach($replacement_keys as $key => $value)
{
foreach($value as $key2 => $value2)
{
if(isset($array[$key2]))
{
$newArray[$key][$array[$key2]] = $value2;
}
else
{
$newArray[$key][$key2] = $value2;
}
}
}
print_R($newArray);

Answer 3

This should work for you, nice and simple (I'm going to assume that A should be name and B should be code):
(Here I go through each array from $replacement_keys with array_map() and replace the array_keys() with the array_values() of $array. Then I simply get all array values from $replacement_keys and finally I array_combine() the replaced array keys with the corresponding array values)
$result = array_map("array_combine",
array_map(function($v)use($array){
return str_replace(array_keys($array), array_values($array), array_keys($v));
}, $replacement_keys),
$replacement_keys
);
output:
Array ( [0] => Array ( [code] => sara [name] => 2020 ) [1] => Array ( [code] => ahmed [name] => 1010 ) )
