Please help me understand this PHP script.Noob here
- by NissGTR
I'm learning PHP,MySQL and came across this function today
function get_director($director_id) {
global $db;
$query = 'SELECT
people_fullname
FROM
people
WHERE
people_id = ' . $director_id;
$result = mysql_query($query, $db) or die(mysql_error($db));
$row = mysql_fetch_assoc($result);
extract($row);
return $people_fullname;
}
I understand what functions are and I've created a few while learning PHP.But this one is a bit more complicated.I can't understand the
WHERE people_id = ' . $director_id
I'm new to MySQL.I guess the single quote ends the MySQL statement?And then it is concatenated with the argument? Please help me out.
