I tried googling it but unable to find anything close. Is it possible to merge two array but actually a part of second array?
These array would be very long and on second I want to just use the categories from second array and merge in first!
My array:
$ar1 = array(
"locale" => "en-US",
"id" => 1,
"categories" => array(
"0" => array("name" => "abc", "username" => "abc1"),
"1" => array("name" => "cdf", "username" => "bbb3"),
)
);
$ar2 = array(
"locale" => "en-US",
"id" => 1,
"categories" => array(
"0" => array("name" => "xyz", "username" => "xyz4"),
"1" => array("name" => "zyx", "username" => "xtt44"),
)
);
I tried array_merge, array_merge_recursive but it does not work.
I am getting
Array
(
[locale] => Array
(
[0] => en-US
[1] => en-US
)
[id] => Array
(
[0] => 1
[1] => 1
)
[categories] => Array
(
[0] => Array
(
[name] => abc
[username] => abc1
)
[1] => Array
(
[name] => cdf
[username] => bbb3
)
[2] => Array
(
[name] => xyz
[username] => xyz4
)
[3] => Array
(
[name] => zyx
[username] => xtt44
)
)
)
But this is what I want:
Array
(
[locale] => Array
(
[0] => en-US
)
[id] => Array
(
[0] => 1
)
[categories] => Array
(
[0] => Array
(
[name] => abc
[username] => abc1
)
[1] => Array
(
[name] => cdf
[username] => bbb3
)
[2] => Array
(
[name] => xyz
[username] => xyz4
)
[3] => Array
(
[name] => zyx
[username] => xtt44
)
)
)
This may not be a Built-In Function. Yes; it is just a nested Loop with branched out conditionals. Test it... and see if (most importantly) it does what you want... the rest is a matter of choice: Simplicity over complexity.
Here are the Given Arrays: $ar1 and $ar2
<?php
$ar1 = array(
"locale" => "en-US",
"id" => 1,
"categories" => array(
"0" => array("name" => "abc", "username" => "abc1"),
"1" => array("name" => "cdf", "username" => "bbb3"),
)
);
$ar2 = array(
"locale" => "en-US",
"id" => 1,
"categories" => array(
"0" => array("name" => "xyz", "username" => "xyz4"),
"1" => array("name" => "zyx", "username" => "xtt44"),
)
);
And here's to the Looping Construct:
<?php
$arrResult = array();
foreach($ar1 as $key=>$value){
if(!array_key_exists($key, $arrResult)){
if(is_array($value)){
$arrResult[$key] = array();
for($i=0; $i<count($value); $i++){
$arrResult[$key][] = $value[$i];
}
}else{
$arrResult[$key] = $value;
}
foreach ($ar2 as $index => $item) {
if(!array_key_exists($index, $arrResult)){
if(is_array($item)){
if($key == $index) {
$arrResult[$index] = array();
for ($j = 0; $j < count($item); $j++) {
$arrResult[$key][] = $item[$j];
}
}
}
}else{
if(is_array($item)){
if($key == $index) {
for ($j = 0; $j < count($item); $j++) {
array_push($arrResult[$index], $item[$j]);
}
}
}else{
$arrResult[$index] = $item;
}
}
}
}
}
var_dump($arrResult);
?>
Here is the Output of the var_dump():
array (size=3)
'locale' => string 'en-US' (length=5)
'id' => int 1
'categories' =>
array (size=4)
0 =>
array (size=2)
'name' => string 'abc' (length=3)
'username' => string 'abc1' (length=4)
1 =>
array (size=2)
'name' => string 'cdf' (length=3)
'username' => string 'bbb3' (length=4)
2 =>
array (size=2)
'name' => string 'xyz' (length=3)
'username' => string 'xyz4' (length=4)
3 =>
array (size=2)
'name' => string 'zyx' (length=3)
'username' => string 'xtt44' (length=5)
I still believe you may need to add your own logic (if you like it) depending on your use-case and preference.
