PHP：合并两个对象数组

Question

Array 1:

array (size=1)
   0 => 
      object(stdClass)[93]
         public 'case' => string '12571' (length=5)
         public 'status' => string 'aktiv' (length=5)
         public 'id' => string '001345821' (length=9)
         public 'expires' => string '1392681600' (length=10)

Array 2:

array (size=66)
   0 => 
     object(stdClass)[25]
       public 'id' => string '001345821' (length=9)
       public 'date' => int 1415602800
       public 'amount' => string '1069.31' (length=7)
   1 => 
     object(stdClass)[26]
       public 'id' => string '001345680' (length=9)
       public 'date' => int 1415602800
       public 'amount' => string '1035.00' (length=7)

I want to merge array 1 and 2 on the "id" field and only keeping matches from array 1.

What i want:

array ()
   0 =>
     object(stdClass)
       public 'case' => string '1257' (length=5)
       public 'status' => string 'aktiv' (length=5)
       public 'id' => string '001345821' (length=9)
       public 'expires' => string '1392681600' (length=10)
       public 'date' => int 1415602800
       public 'amount' => string '1069.31' (length=7)

Answer 1

If your object contains only properties, you could use array merge in this case. Of course, first up, just use a loop. Then under the loop, make your if checking for those who share the same ids then you need to cast them as array them merge, then recast them as object again:

foreach($array2 as &$value2) {
    foreach($array1 as $value1) {
        if($value2->id == $value1->id) {
            $value2 = (object) array_merge((array) $value2, (array) $value1);
        }
    }
}
