...so ROLLBACK executes , this [the ROLLBACK] do NOT work...

The below code most times work success, but if at line:
(!($result && $result1 && $result3)) {
one is FALSE so whole is TRUE so ROLLBACK executes , this [the ROLLBACK] do NOT work, tables updated rather rollback, and nothing get updated , well ?
I tried both

1. @mysql_query("BEGIN");
2. begin();

...

Code:
<?php
				$query2 = "SELECT * FROM $CustomersTable WHERE status='active' AND email='".$_POST['email2']."' AND password='".$_POST['password2']."';";  
				$result2 = @mysql_query($query2,$linkid);
				$count2 = @mysql_num_rows($result2);
				mysql_free_result($result2);
				if ($count2 > 0) { 
					function begin()
					{
						@mysql_query("BEGIN");
					}
					function commit()
					{
						@mysql_query("COMMIT");
					}
					function rollback()
					{
						@mysql_query("ROLLBACK");
					}
					
					@mysql_query("BEGIN");  
					$query ='';
					$query = "UPDATE $CustomersTable SET status='deleted' WHERE status='active' AND email='$email2' AND password='$password2';";  
					
					$query1 ="INSERT INTO $CanceledCustomersTable SELECT * FROM $CustomersTable WHERE status='deleted' AND email='$email2' AND password='$password2';";
					
					$query4 = "SELECT * FROM $BookingsTable WHERE email='$email2'"; 
					$result4 = @mysql_query($query4,$linkid);
					$count4 = @mysql_num_rows($result4);
					if ($count4>0) {
						$query3 = "UPDATE $BookingsTable SET status='k' WHERE email='$email2';";  
						$result3 = @mysql_query($query3,$linkid); 		
					} else {
						$result3 = true;
					}
					
					$result = @mysql_query($query,$linkid); 
					$result1 = @mysql_query($query1,$linkid); 
					if (!($result && $result3)) {    // $result1 && 
					   echo "<p align='center'>Unable to execute Query(wrong UserName/Password),<br /> please go back and retry... redirecting...</p>";
					   mysql_close($linkid);
					   sleep(6); 
					   @mysql_query("ROLLBACK");  ?>
					   <script type="text/javascript">alert("Please check that you've entered CORRECT Password! Redirecting to previous WebPage ... ");setTimeout(location.href="https://www.poliscarhire.com/customeradmin/register-ac-modify.php",5000);</script><?php
					   exit();
					} else {
					  unset($_SESSION["email"]);
					  unset($_SESSION["password"]);
					  @mysql_query("COMMIT"); 

					  $subject = "Delete Account Notification";
					  $message_del_ac = "<p align='center'>Your Account with PolisCarHire.com ( ID= $email2 ) has been Deleted Permanently. </p><p align='center'>This is the last notification sent ! If you like to reopen an	Account please <a href='https://www.poliscarhire.com/customeradmin/register-ac.php'>Register Here</a>, thks ! </p>";
						$headers = "From:info@poliscarhire.com";                     
						$headers .= "\nReply-To:info@poliscarhire.com"; 
						$headers .= "\nContent-Type: text/html; charset=UTF-8";
						$headers .= "\nMIME-Version: 1.0";  
						$email3 = "$email2,info@poliscarhire.com";
						mail($email3,$subject,$message_del_ac,$headers); 
						mysql_close($linkid);
					  ?>
					  <p>&nbsp;</p>
					  <p align="center">Your Account with PolisCarHire.com ( ID=&nbsp;<?= $email2 ?>&nbsp;) has been Deleted Permanently. </p>
					  <p align="center">An Email notification sent ! If you like to reopen an Account please <a href="register-ac.php">Register Here</a>, thks ! </p>
<?                 }
                } else {	 	  
               		echo "Please check that you've entered CORRECT Password! Redirecting to previous WebPage ... ";
				    mysql_close($linkid);
					?><script type="text/javascript">alert("Please check that you've entered CORRECT Password! Redirecting to previous WebPage ... ");setTimeout(location.href="https://www.poliscarhire.com/customeradmin/register-ac-modify.php",5000);</script><?php
			   }
	?>
