<?php
// To use the class, you will first need to include the class file
include "class.phpMysqlConnection.php";
// The next step will be to set up a variable to represent the object
// created. I usually use the name 'sql' for clarity, but it can be whatever.
$sql=new phpMysqlConnection($sql_user,$sql_pass,$sql_host);
// I usually use this format, and store the variables in a different
// include file with other site-wide config settings. If you leave out
// $sql_host from the above line, "localhost" (when MySQL server and web
// server are on the same machine) is assumed.
// Once connected, select your database that you'll be using
$sql->SelectDB($sql_database);
// The query format is that of mysql, so you don't need to learn any query
// syntax with my class. All you need to do is figure out which query
// function to use.
// To get the results of a multiple row query, you would use something
// similar to this:
$sql->Query(select id, value from table order by id);
for($i=0;$i<$sql->rows;$i++){ // for each row of results
$sql->GetRow($i); // get the data for row $i
// store row elements in variables if necessary
$id=$sql->data['id'];
$value=$sql->data['value'];
// The $sql->data array is an associative array, but if you has a query
// similar to "select id, value, something from table", you could also get
// the values in the for loop using something like this:
$id=$sql->data[0];
$value=$sql->data[1];
// do stuff with this row's data
}
// When you want to do a query when you know there will only be one row
// returned, use the following function:
$sql->QueryRow("select id,value from table where id = '$id'");
// To get the values, just use the data array
$id=$sql->data['id'];
$value=$sql->data['value'];
// or
$id=$sql->data[0];
$value=$sql->data[1];
// If you want to query for a specific cell in your database, you can do so
// like this:
$value=$sql->QueryItem("select value from table where id = '$id'");
// Each time you do a query, $sql->rows & $sql->data are reset, so
// becareful when doing a loop based on query results with additional
// queries inside the loop (unless you initialize another variable like
// $tmp_sql).
