การ SELECT ข้อมูลมีเงื่อนไข WHERE ผ่าน PHP
ใช้ mysql_query() รัน SELECT พร้อม WHERE และ mysql_fetch_array() ดึงข้อมูล
ตัวอย่าง: ดึงระเบียนที่ tutorial_author = 'Sanjay'
<?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 WHERE tutorial_author = "Sanjay"';
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);
?>
