How to fetch data from a joined query in PHP - php

Question

I've a joined query in PHP, which I wanted to join 2 databases VIA the user ID, but I want to be able to fetch data from both tables (users & user_stats), although it's not letting me output any data from the user_stats table, which is leaving me to believe there's a error in my query..
Hence this being my first time using joined tables, could someone please guide me in the correct direction, so far I have:
$getMembers3 = dbquery("SELECT users.id, users.look, users.username
FROM users
JOIN user_stats
ON users.id = user_stats.id
WHERE users.rank < 2 ORDER BY user_stats.Respect DESC LIMIT 10");
Which I am trying to fetch Respects from user_stats VIA:
while ($member2 = mysql_fetch_assoc($getMembers3))
{
echo $member2['user_stats.Respect'] . '<br>';
echo $member2['username'] . '<br>';
}
Although it allows me to view their username from the users table, it won't allow me to view the user_stats.Respect. If someone could enlighten me in the right direction that'd be fantastic.

Answer 1

I always get confused when selecting from mutliple tables and this is how I generally resolve my confusion:
$getMembers3 = dbquery("SELECT users.id as id, users.look as look, users.username as username, user_stats.Respect as respect
FROM users
JOIN user_stats
ON users.id = user_stats.id
WHERE users.rank < 2 ORDER BY user_stats.Respect DESC LIMIT 10");
This way you know what the column names are expected to be. Sidenote, the result set will not have dots in the array keys.
Then you can access results from:
while ($member2 = mysql_fetch_assoc($getMembers3))
{
echo $member2['respect'] . '<br>';
echo $member2['username'] . '<br>';
}

Answer 2

Change your query adding the field in your select statement:
$getMembers3 = dbquery("SELECT users.id, users.look, users.username,user_stats.Respect
FROM users
JOIN user_stats
ON users.id = user_stats.id
WHERE users.rank < 2 ORDER BY user_stats.Respect DESC LIMIT 10");
As a side note you are using a deprecated api to access database that have been removed in PHP 7. Consider switching to PDO and prepared statements.
