mysql - PDO 而不是 MYSQL 函数

Question

上周有人帮助我解决了以下脚本的问题。它被解决了。再次感谢。然而，许多人建议改用 PDO。需要如何为 PDO 编写此脚本？有推荐的示例教程吗？

<?php
$con = mysql_connect("localhost","root","");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

 mysql_select_db("bdcarterascv2", $con);

$COD_PAIS = '3';
$F_HASTACORTE = '2012-03-31 01:00:00';

$result = mysql_query("SELECT mcarteras.DES_CARTERA_CC                 AS 'Short Name of Fund'
     , mcarterasflias.DES_CARTERAFLIA           AS 'I/C'
     , msociedades.DES_SOCIEDAD_CORTO           AS 'Fund Manager Company'
     , mcarteras_clases.DES_CARTERACLASE        AS 'Class'
     , mcarteras_clasesesp.DES_CARTERACLASE_ESP AS 'Special Class'
     , dr_rentmovil_carteras.POR_RENTCARTERA    AS 'TTR year-to-date %'
     , dficha_mes.POR_REMUNERA_COBRADA          AS 'Mgmt Fee Effectively Charged'

我不会将其翻译成 PDO。对于简单的查询，我更喜欢 PDO，但我在纯 SQL 中做的任何复杂的事情。我通常在 JOIN 处画线。
