How To Use:

$MySQL = new MySQL($host, $user, $pass)// Set the Database Class

$MySQL->ChangUser($user, $pass, $db="")// Change the Database User (Unusable in some versoin of MySQL)

$MySQL->OptimizeTab()// Optimize the Tablses of Selected Database

$MySQL->ReadSqlFile($file)// Read SQL File And Send Content of the File to HandleSQL($strSQL)

$MySQL->HandleSQL($strSQL)// Split the SQL Query String into a array from a whole String (Maybe Read from a File)

$MySQL->BatchExec($ArrSQL)// Execute Multi Query from an Array (Use HandleSQL First)

$MySQL->Connect($pconnect = false)// Build a Connection to MySQL to $MySQL->DB_conn

$MySQL->SelectDB($the_db)// Select a Database of MySQL to $MySQL->DB_select (Must Build Connect First)

$MySQL->Query($sql)// Execute a Query of MySQL, Result into $MySQL->DB_resut

$MySQL->SeekData($line)// Seek Data Row in the $MySQL->DB_resut ($MySQL->DB_Qtype Must Be Setted into True Before Query)

$MySQL->GetResult($line, $field="")// The Same Use as mysql_result ($MySQL->DB_Qtype Must Be Setted into True Before Query)

$MySQL->GetRS()// Return The Current Result as an Array and Set the Point of Result to the Next Result

$MySQL->GetStat()// Get the Current Status of MySQL

$MySQL->GetDBs()// Get the Databases List of Current MySQL Server as an Array

$MySQL->GetTabs($the_db)// Get the Tables List of Current Selected Database as an Array

$MySQL->GetIdx($the_tab) // Get the Indexes List of a Table as an Array

$MySQL->GetTabSetting($the_tab)// Get the Whole Struction of Current Selected Database as an Array

$MySQL->GetTabData($the_tab)// Get All of The Data of a Table

$MySQL->GetTabFields($the_db, $the_tab)// Get the Columns List of a Table as an Array

$MySQL->GetQueryFields()// Get the Columns List of Current Query

$MySQL->Free()// Free the $MySQL->DB_result in order to Release the System Resource

$MySQL->Close()// Close Current MySQL Link

$MySQL->Error($str)// Handle the Errors
