Question

I have a table in the following structure…

ID     USER_ID      INTEREST
1      290          soccer
2      290          tennis
3      290          badminton
4      560          netball

I want to grab all values from the table where the user id is equal to the session user id and assign them as variables.

I have the following which works but displays the data very peculiarly..

$interestsquery  = "SELECT * FROM user_interests WHERE user_id = " . $usersClass->userID();
$result = mysql_query($interestsquery);

while($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
 $interests[] = $row['interest'];
 $interest1 = $interests[1];
 $interest2 = $interests[2];
 $interest3 = $interests[3];

 print $interest1 . " - " . $interest2 . " - " . $interest3;

} 

The above however outputs something along the lines of…

- - tennis - - tennis - badminton - 

Can anybody see where I’m going wrong?

Answer 1

This should do what you need:

$interestsquery  = "SELECT `interest` FROM `user_interests` WHERE `user_id` = " . $usersClass->userID();
$result = mysql_query($interestsquery);

$interests = array();
while(list($interest) = mysql_fetch_array($result))
    $interests[] = $interest;

print explode($interests, ' - ');
