What's the issue in inserting a new array element in existing array in PHP?

Question

I'm having an multi dimensional array. Now I want to insert a new key value combination in this array. But I'm not able to do it. Can you help me in achieving this? For your reference i'm giving my code below alongwith the existing multi dimensional array:

Code: $practice_sheet_set_data /Existing multi dimensional array/ /The code for getting the value which is to be inserted in the above array/

$sql  = " SELECT st.staff_full_name FROM ".TBL_STAFF." AS st JOIN ".TBL_PRACTICE_SHEET." AS ps ";
            $sql .= " ON st.staff_id=ps.practice_sheet_created_staff_id WHERE ps.practice_sheet_id= ".$practice_sheet_id;
            $this->mDb->Query( $sql);
            $practice_sheet_created_staff_data = $this->mDb->FetchArray(MYSQL_FETCH_SINGLE);

From tha above code I'm getting an single dimensional array in a variable $practice_sheet_created_staff_data but not able to insert it's value into a above array. I tried array_push and array_merge too. Both the arrays are given below:

I want to create a new key value pair in the previous array as [staff_full_name] => Amol Patil

have you tried $practice_sheet_data[] = $practice_sheet_created_staff_data; — roninblade

If you push name, you may have trouble on foreach. Try this one:

$new_array = array($practice_sheet_created_staff_data['staff_full_name'] => $practice_sheet_data);

And you can get it with var_dump($new_array[0]); or var_dump($new_array['name']);

If what you want to do is insert a new key-pair value have you tried

foreach($practice_sheet_created_staff_data as $key => $value)
 {
  $practice_sheet_created_staff_data[$key][staff_full_name] = 'Amol Patil'
 }

if you want to insert $practice_sheet_created_staff_data into the array then:

$practice_sheet_data[] = $practice_sheet_created_staff_data;
// will give you
// $practice_sheet_data[8] = array('staff_full_name' => 'Amol Patil');

to insert in each child array then:

foreach ($practice_sheet_data as $key => $array) {
  $practice_sheet_data[$key]['staff_full_name'] = $practice_sheet_created_staff_data['staff_full_name'];
}
// will give you 
// $practice_sheet_data[0] = array(... your other elements..., 'staff_full_name' => 'Amol Patil');

if you wanna change result array, try this.

foreach($practice_sheet_created_staff_data as &$p) {
    $p['staff_full_name'] = 'Amol Patil';
    // $p['topic_id'] = 0; // if you wanna the other value.

}

you must type & . it can change values inside array.
