php
I currently have 5 tables in MySQL database. Some of them share foreign keys and are interdependent of each other. I am displaying classes accordingly to their majors. Each class is taught during the fall
, spring
or all_year
. In my database I have a table named semester which has an id
, year
, and semester
fields. The semester
field in particular is a tinyint
that has three values 0
, 1
, 2
. This signifies the fall
, spring
or all_year
. When I display the query instead of having it show 0
or 1
or 2
can I have it show fall
, spring
etc? Extra: How can I add space to the end of each loop so the data doesn't look clustered?
Key
0 Fall
1 Spring
2 All-year

<?
try {
$pdo = new PDO ("mysql:host=$hostname;dbname=$dbname","$username","$pw");
} catch (PDOException $e) {
echo "Failed to get DB handle: " . $e->getMessage() . "\n";
exit;
}
$query = $pdo->prepare("SELECT course.name, course.code, course.description, course.hours, semester.semester, semester.year
FROM course
LEFT JOIN major_course_xref ON course.id = major_course_xref.course_id
LEFT JOIN major ON major.id = major_course_xref.major_id
LEFT JOIN course_semester_xref ON course.id = course_semester_xref.course_id
LEFT JOIN semester ON course_semester_xref.semester_id = semester.id");
$query->execute();
if ($query->execute()){
while ($row = $query->fetch(PDO::FETCH_ASSOC)){
print $row['name'] . "<br>";
print $row['code'] . "<br>";
print $row['description'] . "<br>";
print $row['hours'] . " hrs.<br>";
print $row['semester'] . "<br>";
print $row['year'] . "<br>";
}
}
else
echo 'Could not fetch results.';
unset($pdo);
unset($query);
?>
