Question

这是在codeigniter中打印上次执行的查询的代码

print_r($this->db->last_query());

就像在PHP中打印上次执行的查询的代码是什么？

Answer 1

您可以执行以下操作来获取上次执行的查询：

$mysql_last_query = ""; //this var contains the last mysql query
function query($sql, $args) { #sintax: query("query", "arg1", "arg2", "argn"); EXAMPLE: query("select * from %s", $_GET["table"]);
    global $mysql_last_query;
    $args = func_get_args();
    if(($num = func_num_args()) > 1)
        $sql = call_user_func_array("sprintf", $args);
    $mysql_last_query = $sql;
    return mysql_query($sql);
}
function select($table, $what = "*", $where = "", $limit = ""){ #this function is a "shortcut" for mysql select EXAMPLE: select("blah"); //SELECT * FROM blah and so on
    return mysql_query("SELECT ".$what." FROM ".$table.($where == "" ? "":(" WHERE ".$where)).($limit == "" ? "":(" LIMIT ".$limit)));
}

希望有所帮助
