Objective

With PHP for the first time, functional requirements are simple: to provide a web interface, receive data, and then interact with the database, ultimately responding to XML results. The process is exposed to many of PHP's common syntax and functions, such as PDO operations on the database, XML operations, object-oriented, regular expressions, output output ... Wait a minute. The basic is the Internet search example, and then groped themselves to write code, Because the. NET has been written for n years, the project process has been greatly influenced by. NET, with a three-tier architecture, and even a codebehind-like class for each PHP interface, without the time to understand the development framework under PHP and the projects that are built entirely on their own ideas. In this essay record, in order to later memo query, also want to get PHP professional guidance.

DAL

Originally wanted to encapsulate a dbutility class, but a few days time can not be fully understood PDO and apply freely, have to mix database related operations in the DAL.

Code

/* ***********************************************************

Class DAL

constructor function
Public Function __construct ()

Determine if the grouping exists
Public Function groupexist ($grpid)
{
$this, PDO = new PDO (Db_basic, Db_user, DB_PSWD);
$cmd = "Select COUNT (*) from Extension_group WHERE ' grp_id ' =". $grpid;
$rs = Query ($cmd), PDO, $this
$arr = $rs-Fetchall ();
$this, PDO = null;
if ($arr [0] [0] = = 1)
{
return true;
}
Else
{
return false;
}
}

Determine if an extension exists
Public Function extensionexist ($ETN)
{
$this, PDO = new PDO (Db_basic, Db_user, DB_PSWD);

$arr = $rs-Fetchall ();
$this, PDO = null;
if ($arr [0] [0] = = 1)
{
return true;
}
Else
{
return false;
}
}

Add extension (extension number, group Id,email, name, remark)
Public Function Extensionadd ($ETN, $grpid, $email, $name, $desc)
{
/* Prepare Way

$this, PDO = null;

if ($s = = 1) {

}
else {

Activate extension
Public Function Extensionact ($ETN, $state)

Ui

Although there is no correlation between events and page controls in PHP like Codebehind, there is no object inheritance relationship between the classes and pages, but it is still felt that such separation logic will be clearer and may be used for a long time. Net of inertia thinking, do not like to put logic code nested in the page.
