Re: [PHP-DB] using PDO vs mysql extension

Hi,
I want to build an internal module for common DB-involved tasks: starting
with connection, simple queries and go on to multiple pages of results and
connecting tables and so on.
We are currently working with MySQL but maybe in the future we'll add use of
MSSQL (but it's negligible in comparison with the MYSQL percentage of use).
I wonder if to base my functions on the abstract layer of PDO or to use
mysql function (means mysql_connect and so on).
As I see it, mysql functions are more readable and comfortable, but in this
case : using MSSQL in the future would affect with new DB module with
another implementation.
What do would do in such a situation??
You could stick with the native mysql_* and mysqli_* functions,
but if you have any hint that your application may eventually change
its database platform, or if you at least want the option to easily
swap, you should definitely use abstraction. You could use PDO or, as
I did, create your own abstraction layers with a common application
interface. Then all you need to do is change a configuration variable
if you need to switch from, say, MySQL to SQL Server, PostgreSQL, et
cetera. The application never notices a difference. For example:
?php
define('DB_PLATFORM','mysql');
$db = new DB(DB_PLATFORM);
$db-select('*','tablename');
?
There will be some pitfalls and intricacies now and again that
require some additional adjustments in the model, but I've found that,
for myself, I prefer having full control over the code. Well,
that and the fact that it was a specific requirement in the spec
of the project.

[PHP-DB] combining the results of mysql query and finding the unique tuples in php
Hi
I have a certain number of mysql tables(relation), say 50, some of them
having 5 fields and some with 6 fields. a particular search item may be
found in multiple tables with multiple rows. I am using a loop to find all
those.
My problem is I want to first combine all those results and then find all
the unique entries. (the query results may overlap).
What is the best way to do it?
I am trying to make my code as simple as possible:
Suppose I have $nRows number of tables;
for ($j = 0 ; $j $nRows ; $j++)
{
$query = select * from .$tables[$j]. where
name='xx';
$qRes = mysql_query($query);
if (!$qRes) die (Database access failed: .
mysql_error());
$numRow = mysql_num_rows($qRes);
$numCol = mysql_num_fields($qRes);
for ($k = 0 ; $k $numRow ; $k++)
{
$resRow = mysql_fetch_row($q1Res);
echo 'tr';
for ($l = 0; $l$numCol; $l++)
{
echo td$resRow[$l]/td;
}
echo/tr;
}
}
This code is printing following values fetched from different table that may
be duplicate. I just want the unique rows.

Re: [PHP-DB] Connecting PHP to MySQL on Windows
Hi, I swapped out 'localhost for '127.0.0.1' in the url but this had no effect. I had a look at my hosts file at c:\windows\system32\drivers\etc and this contained: # Copyright (c) 1993-2006 Microsoft Corp. # # This is a sample HOSTS file used by Microsoft TCP/IP for Windows. # # This file contains the mappings of IP addresses to host names. Each # entry should be kept on an individual line. The IP address should # be placed in the first column followed by the corresponding host name. # The IP address and the host name should be separated by at least one # space. # # Additionally, comments (such as these) may be inserted on individual # lines or following the machine name denoted by a '#' symbol. # # For example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host 127.0.0.1 localhost ::1 localhost and so this seems fine as well. cheers Mike On Fri, Jan 7, 2011 at 1:25 PM, Daniel Brown danbr...@php.net wrote: On Thu, Jan 6, 2011 at 21:12, michael manning michaelgmann...@gmail.com wrote: Hi Daniel, When testing with the CLI, netstat shows: [snip!] What happens when you swap out 'localhost' for '127.0.0.1' in the connection routine?
