This section provides a tutorial example on how to use MySQL functions to connect to a MySQL server, and run SQL statements to create a table, insert rows and fetch rows with the MySQL server.
To show you how some of those MySQL functions should be used, I wrote this simple script, MySqlLoop.php:
<?php # MySqlLoop.php #- Copyright (c) HerongYang.com. All Rights Reserved. # $con = mysql_connect('localhost'); $rs = mysql_query('DROP DATABASE MyBase'); $rs = mysql_query('CREATE DATABASE MyBase'); $rs = mysql_query('USE MyBase'); print "Creating a table...\n"; $rs = mysql_query('CREATE TABLE MyTable (ID INTEGER,' .' Value INTEGER)'); $n = 100; $i = 0; print "Inserting some rows to the table...\n"; while ($i < $n) { $rs = mysql_query('INSERT INTO MyTable VALUES ('.$i.', ' .rand(0,$n-1).')'); $i++; } print "Query some rows from the table...\n"; $rs = mysql_query('SELECT * FROM MyTable WHERE ID < 10'); print " ".mysql_field_name($rs,0)." " .mysql_field_name($rs,1)."\n"; while ($row = mysql_fetch_array($rs)) { print " ".$row[0].' '.$row[1]."\n"; } mysql_free_result($rs); mysql_close($con); function mysqli_field_name($result, $field_offset) { $properties = mysqli_fetch_field_direct($result, $field_offset); return is_object($properties) ? $properties->name : null; } ?>
Note that if the connection resource is not specified in a query call, the last connection resource will be used. If you run this script, you will get something like:
Creating a table... Inserting some rows to the table... Query some rows from the table... ID Value 0 14 1 91 2 84 3 16 4 88 5 51 6 12 7 19 8 39 9 5
