PHP : merging array with same element

Question

I need a new array to merge all category_name with same exercise_name, i.e. it would be:

Array
    (
[0] => stdClass Object
    (

        [exercise_name] => Hang Clean
        [category_name] => Heavy,Pull,Core
    )

[1] => stdClass Object
    (

        [exercise_name] => Ice Skaters
        [category_name] => Ground,Lower,Plyometrics
    )

[2] => stdClass Object
    (

        [exercise_name] => Ice Skaters
        [category_name] => Basketball,Sport Specific
    )

)

Output :

Array
(
    [0] => stdClass Object
        (
            [exercise_name] => Hang Clean
            [multiple_category_name] => Array
                (
                    [0] => Heavy,Pull,Core
                )

        )

    [1] => stdClass Object
        (
            [exercise_name] => Ice Skaters
            [multiple_category_name] => Array
                (
                    [0] => Ground,Lower,Plyometrics
                    [1] => Basketball,Sport Specific
                )

        )

)

What is the best way to merge all category_name with same exercise_name?

Any solution?

This may help you

 [akshay@localhost tmp]$ cat test.php
 <?php 

 $array= array(
               (object)array("exercise_name" => "Hang Clean","category_name" => "Heavy,Pull,Core"),
               (object)array("exercise_name" => "Ice Skaters","category_name" => "Ground,Lower,Plyometrics"),
               (object)array("exercise_name" => "Ice Skaters","category_name" => "Basketball,Sport Specific")
              );


 function simple_merge($array)
 {

    foreach($array as $k)
    {
       if(isset($output[$k->exercise_name]))
       { 
           array_push($output[$k->exercise_name]->multiple_category_name,$k->category_name);    
       }else
       {    
           $k->multiple_category_name  = array($k->category_name);
           unset($k->category_name);
           $output[$k->exercise_name]  = $k;
       }        
    }

    return array_values($output);
 }


 // Input 
 print_r($array);

 // Output
 print_r(simple_merge($array));

Try this one,

$new = array();
foreach($obj as $key=>$val {
   if($key == "exercise_name") {
     $key1 = $val;
   }

   if($key == "category_name") {
     $new[$key1] = $val;
   }


}

print_r($new);

                    if(trim($result->exercise_name) == trim($obj1->exercise_name)){
                        $check = 1;
                        $results[$key]->multiple_category_name[] = $obj1->category_name;
                        continue;
