PHP - user membership list using mysql two tables - php

Question

I want to make a membership list to show from two tables.
I want to join the two tables on there id's
database table - user
,
database table - user_data
Currently I'm getting only the id=1 from user table with user data as well.
I know I want to loop it to see all the records from the user table but I don't how too. I am new to coding.
{
$result = mysql_query("SELECT * FROM user WHERE user_active='Yes' AND user_id!=0 ") or die(mysql_error());
$row = mysql_fetch_array($result,MYSQL_ASSOC);
foreach ($row as $key => $value) {
$output[$key] = $value;
}
$user_id=$output['user_id'];
// now we get the user information and add it to the $output array.
$result = mysql_query("SELECT data_type,data_value FROM user_data WHERE data_user_id=$user_id ") or die(mysql_error());
while($row = mysql_fetch_array($result,MYSQL_ASSOC)) {
$output['user_data'][$row['data_type']] = $row['data_value'];
}
print_r($output);
}

Only one request is needed in this context you have to rewrite your SQL call.
SELECT u.user_id, u.user_active, ud.data_type, ud.data_value FROM user u
JOIN user_data ud
ON u.user_id = ud.user_id
WHERE u.user_active='Yes' AND data_user_id!=0
I JOIN the 2 tables with ALIAS tables u and ud (user,user_data) with the same id in your context user_id and data_user_id :
// now we get the user information and add it to the $output array.
$result = mysql_query("SELECT u.user_id, u.user_active, ud.data_type, ud.data_value FROM user u
JOIN user_data ud
ON u.user_id = ud.user_id
WHERE u.user_active='Yes' AND data_user_id!=0") or die(mysql_error());
while($row = mysql_fetch_array($result,MYSQL_ASSOC)) {
$output['user_data'][$row['data_type']] = $row['data_value'];
}
print_r($output);
