[PHP-DB] how to explain such a regular syntax
Its was picked from drupal source code and i don't know how does it works.
This is the code :
preg_match('/^\[?(?:[a-z0-9-:\]_]+\.?)+$/', $host);
After followed the regular syntax ,i try to cut it into pieces to make
it simpler to
understand ,
part a1: ^\[?
part a2:([a-z0-9-:\]_]+\.?)+$
Then go on cut part a2:
a2_1: ?:
a2_2: ([a-z0-9-:\]_]+\.?)+$
a2_3: a2_2 and +$
a1 means:start with nothing or one ?
a2_2 means character must be in a-z,0-9 ,],_ and the number must
be only one
a2_3 means there must be one and only matched a2_2 string .
And i dint't got a2_1 mean.
Anyone could explain the it works and the fault of my analysis are appreciated!
All you best

[PHP-DB] Re: pear template revoke problem
The problem resolved because the following line:
$tpl = new HTML_Template_IT(./template);
changed to :
$tpl = new HTML_Template_IT(.);
the .php works fine.

[PHP-DB] Call two class object failed
Hi my friend,i wrote two classed on is user,the other is db .The user
have a property which from the db class object .
When i writing my application have both class object invoked at the
same time ,just like
$user_a = new user($para);
$db_a = new db()
Then the problem occurs only one of the class object could work, or
$user_a or $db_a not both,What 's problem of my code
The following is my source code:
class db{
/**
* Constructor
*/
var $result;
var $conn;
function db(){
require_once BOC_BASE_DIR.'/config/db.config.inc';
$this-conn = mysql_connect($db_host,$db_user,$db_pass);
//$this-conn = @mysql_connect($db_host,$db_user,$db_pass);
if (!$this-conn) {
$this-db_print_error(DB connect failed);
}
if (!mysql_select_db($db_name,$this-conn)) {
$this-db_print_error(DB select failed);
}
}
class user{
private $u_sn;
private $u_id;
private $u_name;
private $u_sex;
private $u_image;
//more property
private $u_info;
/**
* Constructor
*/
function __construct($name){
$sql = select * from boc_user where u_name = '$name';
$u_query = new db();
$this-u_info = array();
$u_query-db_query($sql);
$this-u_info =$u_query-db_fetch_row();
$this-u_sn = $this-u_info['u_sn'];
$this-u_id = $this-u_info['u_id'];
$this-u_name = $this-u_info['u_name'];
$this-u_sex = $this-u_info['u_sex'];
//more are give the property value
}
The two class works well in the single application when only of them
are invoked ,i cost me much time to deal it
Any advice and suggestions are thankful !
All you best
