- 1. Min Yang Jung November 13, 2008
- 2. Open a connection <?php $dbhost = 'localhost'; $dbhost = 'db.php-mysql-tutorial.com:3306'; $dbuser = 'root'; $dbpass = 'password'; $conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ('Error connecting to mysql'); $dbname = 'petstore'; mysql_select_db($dbname); ?>
- 3. Close a connection <?php // it does nothing but closing // a mysql database connection mysql_close($conn); ?>
- 4. SELECT <?php include 'config.php'; include 'opendb.php'; $query = "SELECT name, subject, message FROM contact"; $result = mysql_query($query); while($row = mysql_fetch_row($result)) { $name = $row[0]; $subject = $row[1]; $message = $row[2]; echo "Name :$name <br>" . "Subject : $subject <br>" . "Message : $row <br><br>"; }
- 5. INSERT <?php include 'config.php'; include 'opendb.php'; mysql_select_db($mysql); $query = "INSERT INTO user (host, user, password, select_pr iv, insert_priv, update_ priv) VALUES ('localhost', 'phpcak e', PASSWORD('mypass'), 'Y', 'Y', 'Y')"; mysql_query($query) or die('Error, insert query failed'); $query = "FLUSH PRIVILEGES"; mysql_query($query) or die('Error, insert query failed'); include 'closedb.php‘ ?>
- 6. Open a Connection #!/usr/bin/perl use Mysql; print "Content-type: text/html nn"; $host = "localhost"; $database = "store"; $tablename = "inventory"; $user = "username"; $pw = "password"; $connect = Mysql->connect($host, $database, $user, $pw); $connect->selectdb($database);
- 7. Close a Connection # free result set mysql_free_result($result); # close the connection mysql_close($connect); ?>
- 8. SELECT # DEFINE A MySQL QUERY $myquery = "SELECT * FROM $tablename"; $execute = $connect->query($myquery); $rownumber = $execute->numrows(); $fieldnumber = $execute->numfields(); # PRINT THE RESULTS print $rownumber."<br />"; print $fieldnumber."<br />";
- 9. INSERT $myquery = "INSERT INTO $tablename (id, product, quantity) VALUES (DEFAULT,'pineapples','15')"; $execute = $connect->query($myquery); $affectedrows = $execute->affectedrows($myquery); $lastid = $execute->insertid($myquery); print $affectedrows."<br />"; print $lastid."<br />";
