sql - php match cells from 2 databases and pull out cell info -


i have users database , person database

in users database have following cells

id, firstname, lastname, person_id

in person database have following cells

id, firstname, phone

i show out phone person db based on person_id users db (the id in users db , person db not same therefore need match ids thru users.person_id phone)

this how far - without luck though... nothing shows:

$query = "select person_id user person.id=$user_person_id"; $result = mysql_query($query); $line = mysql_fetch_object($result); echo "phone: $line[$phone]";

hopefully, if understand question well, sql joins you. here using left join. try read more joins.

 $sql = "select `users`.`id`, `users`.`firstname`, `users`.`lastname`, `person`.`phone` `users` left join `person` on `users`.`person_id` = `person`.`id`";   $query = $mysql_query ($sql);  $result = $mysql_fecth_assoc ($query);   echo 'phone: ', $result['phone'];

here errors:

  1. from comments fetching results object yet displaying array. $line = $mysql_fetch_object($result);
  2. you using variable array key. $line[$phone];

try these new codes. hope should work.
