SQL JOIN replacing an unwanted column - php

Question

I created a JOIN query to be able to access the username column from the users table where t.user_id = u.id.
Unfortunately, there is an issue since creating this query. Now when I try to use the id from the triggers table, my variable is picking up the id from the users table.
Does anyone see how I can fix this?
try {
$con = getConfig('pdo');
$con->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql_triggers = "
SELECT
t.*,
u.id,
u.username
FROM
triggers AS t
LEFT JOIN
users AS u ON t.user_id = u.id
";
$triggers_stmt = $con->prepare($sql_triggers);
$triggers_stmt->execute();
$triggers_rows = $triggers_stmt->fetchAll(PDO::FETCH_ASSOC);
$triggers_arr = array();
foreach ($triggers_rows as $triggers_row) {
$trigger_id = $triggers_row['id'];
$trigger_title = $triggers_row['trigger_name'];
$trigger_description = $triggers_row['description'];
$trigger_setting = $triggers_row['setting'];
$trigger_user = $triggers_row['user_id'];
$trigger_username = $triggers_row['username'];
triggers = t

I was able to modify the SQL to get the result I was looking for. The users id column was clashing with the triggers id column. As NigelRen pointed out, changing u.id, to u.id AS uid, solved this issue.
SELECT
t.*,
u.id AS uid,
u.username
FROM
triggers AS t
LEFT JOIN
users AS u ON t.user_id = u.id
";
