I need solution for How to compare two key and value and find max key value from array.

explain:- I have below array in this if **url** and **con code** both are same than higher **amount** array should display and unmatch data should be display please provide sollution for same .

$array = array(
array(
"id" => 1,
"amount" => 10,
"url" => 'https://play.google.com/store/apps/details?id=com.my.heroesofutopia',
"con" => array('US' =>array('id'=> '1','code'=>'US')),
),
array(
"id" => 2,
"amount" => 3,
"url" => 'https://play.google.com/store/apps/details?id=com.my.heroesofutopia' ,
"con" => array('US' =>array('id'=> '1','code'=>'US')),
),
array(
"id" => 3,
"amount" => 19,
"url" => 'https://play.google.com/store/apps/details?id=com.my.heroesofutopia' ,
"con" => array('US' =>array('id'=> '1','code'=>'US'),'Uk' =>array('id'=> '2','code'=>'UK')),
),
array(
"id" => 4,
"amount" => 50,
"url" => 'https://play.google.com/store/apps/details?id=com.my.heroesofutopia1111' ,
"con" => array('US' =>array('id'=> '1','code'=>'US'),'Uk' =>array('id'=> '2','code'=>'UK')),
),
);

Please check result i want
in this example 1 and 2 id have same url and country code so from this two we have to choose higher amount one.so we choose this and id 3 and 4 are not match this criteria so its will remain same in this array because ID 3 has same url but has different country code and ID 4 has different url.

i want this result.please provide sollution for same,
thanks in advance...!!

array( "id" => 1,
"amount" => 10,
"url" => 'https://play.google.com/store/apps/details?id=com.my.heroesofutopia',
"con" => array('US' =>array('id'=> '1','code'=>'US')),
),
array(
"id" => 3,
"amount" => 19,
"url" => 'https://play.google.com/store/apps/details?id=com.my.heroesofutopia' ,
"con" => array('US' =>array('id'=> '1','code'=>'US'),'Uk' =>array('id'=> '2','code'=>'UK')),
),
array(
"id" => 4,
"amount" => 50,
"url" => 'https://play.google.com/store/apps/details?id=com.my.heroesofutopia1111' ,
"con" => array('US' =>array('id'=> '1','code'=>'US'),'Uk' =>array('id'=> '2','code'=>'UK')),
),

What I have tried:

My code is for that is



$output = [];
foreach($array as $data){

if(!isset($output[$data['url']]) ){

$output[$data['url']] = $data;

}
elseif( $output[$data['url']]['amount'] < $data['amount']){

$output[$data['url']] = $data;
}

}
echo "

"; print_r($output);
