php - Foreach returned $variable[] select from database and combine values -

i have tried around couple of ways , different manners no luck. (also searched different solutions) sure i'm missing something.

i have following code:

$variable = returned array eg. 7, 8, 9; foreach($variable $entry_id){     $query = mysql_query("select * table entry_id=$entry_id") or die (mysql_error());     while($row = mysql_fethc_array($query)){         $qty = $row['quantity'];         $combination = array_combine($qty);     } } 

everything works , correct quantities returned (on testing) combinations not correct. combinations - of each entry_id - combined next one.

instead of receiveing eg.

$entry_id(7) = 15; $entry_id(8) = 26; $entry_id(9) = 58; 

i getting:

$entry_id(7) = 15; $entry_id(8) = 41; $entry_id(9) = 99; 

the table structure this:

entry_id | quantity 7        | 5 7        | 5 9        | 29 8        | 26 7        | 5 9        | 29
