codeigniter：从数组1插入值到数组2？

Question

i have an array like this

array 1

array(3) { 
   [0]=> string(2) "47" 
   [1]=> string(2) "48" 
   [2]=> string(2) "49" 
} 

i have plan to giving array with name, the array name is number

array 2

array(3) { 
[0]=> object(stdClass)#18 (2) { 
      ["address"]=> string(9) "Address 1" 
      ["price"]=> string(16) "120000" } 
[1]=> object(stdClass)#21 (2) { 
      ["address"]=> string(9) "Address 2"      
      ["price"]=> string(16) "150000" } 
[2]=> object(stdClass)#20 (2) { 
      ["address"]=> string(9) "Address 3" 
      ["price"]=> string(16) "180000" } 
}

I want to inserting array 1 into array 2 which same array key

I want to insert array 1 data into array 2 accordance with the key array . so i I was expecting to be joined both of arrays and became joined array like this

array(3) { 
[0]=> object(stdClass)#18 (2) { 
      ["address"]=> string(9) "Address 1" 
      ["price"]=> string(16) "120000" 
      ["number"]=> string(2) "47" } 
[1]=> object(stdClass)#21 (2) { 
      ["address"]=> string(9) "Address 2"      
      ["price"]=> string(16) "150000" 
      ["number"]=> string(2) "48"} 
[2]=> object(stdClass)#20 (2) { 
      ["address"]=> string(9) "Address 3" 
      ["price"]=> string(16) "180000" 
      ["number"]=> string(2) "49"} 
} 

is there any way to create or manipulate into an array like that ? my array is dynamically so number of array can be changed anytime.

I would greatly appreciate it if you could help me

Answer 1

Read up on the basic language control structures and foreach in particular.

foreach ($array2 as $index => $object) {
    if (isset($array1[$index])) {
        $object->number = $array1[$index];
    }
}

Outcome:

array(3) {
  [0]=>
  object(stdClass)#1 (3) {
    ["address"]=>
    string(9) "Address 1"
    ["price"]=>
    string(6) "120000"
    ["number"]=>
    string(2) "47"
  }
  [1]=>
  object(stdClass)#2 (3) {
    ["address"]=>
    string(9) "Address 2"
    ["price"]=>
    string(6) "150000"
    ["number"]=>
    string(2) "48"
  }
  [2]=>
  object(stdClass)#3 (3) {
    ["address"]=>
    string(9) "Address 3"
    ["price"]=>
    string(6) "180000"
    ["number"]=>
    string(2) "49"
  }
}
