การ ORDER BY ใน PHP MySQL
ใช้ mysql_query() รัน SELECT ... ORDER BY และ mysql_fetch_array() ดึงข้อมูล
ตัวอย่าง: เรียงตาม tutorial_author DESC
<?php
$dbhost = 'localhost:3036';
$dbuser = 'root';
$dbpass = 'rootpassword';
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if(! $conn ) {
die('Could not connect: ' . mysql_error());
}
$sql = 'SELECT tutorial_id, tutorial_title, tutorial_author, submission_date
FROM tutorials_tbl
ORDER BY tutorial_author DESC';
mysql_select_db('TUTORIALS');
$retval = mysql_query($sql, $conn);
if(! $retval ) {
die('Could not get data: ' . mysql_error());
}
while($row = mysql_fetch_array($retval, MYSQL_ASSOC)) {
echo "Tutorial ID :{$row['tutorial_id']} <br> ".
"Title: {$row['tutorial_title']} <br> ".
"Author: {$row['tutorial_author']} <br> ".
"Submission Date : {$row['submission_date']} <br> ".
"--------------------------------<br>";
}
echo "Fetched data successfully\n";
mysql_close($conn);
?>ผลลัพธ์จะเรียงตัวอักษรผู้แต่งจาก Z ถึง A
