RE: [PHP] socket_read can not read the whole HTTP page?
Wow, That's correct answer! Thank to Eddie Dunckley !
scheme:
$in .= GET {$file} HTTP/1.0\r\n; //---
$in .= Accept: text/html\r\n;
$in .= Accept-Language: zh-cn\r\n;
$in .= User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET
CLR 2.0.50727)\r\n;
$in .= Host: {$host}\r\n;
$in .= Cache-Control: no-cache\r\n;
$in .= Connection: closed\r\n\r\n;//must be closed
1.must be HTTP/1.0 : why? IE post HTTP/1.1 .
2. must be closed : so that should be close not closed;
Both modification are required.
Shall anyone tell me sth. about HTTP/1.0 and HTTP/1.1 ?
best regards!

[PHP] socket_read can not read the whole HTTP page?
I wrote those script to get HTTP url content, and it works , but it can't
read the whole content of the page.
Blocked on while ($out = socket_read($socket, 1024)) .
browser show the processbar all the time , and the page is not completed
display,
If I press ESC key to cancel the request , the resource of page show that :
the target URL were not read completed .
next codes never been executed .
Why socket_read blocked?
Additional : The network and URL are absolute valid all the time . the size
of target page is about 30k bits .
script :

RE: [PHP] Try{} Catch()
use it just like in JAVA, It offers a uniform/good way to manage exception
in app.
e.g.
function getObjFromDB($key)
{
if (strlen($key)!=0 )
throw new Exception (need condition .);
if (!mysql_connect(...))
throw new Exception (can't connect to db .);
.
}
function foo ()
{
$err='';
for (...)
{
try
{
getObjFromDB('');
}
catch (Exception $e) // if you throw a exception but didn't catch it , the
PHP app will stop and not prompt any error message.
{
echo $e; //output the error message.
$err .= $e;
}
}
echo done , total message : {$err};

You create exceptions for errors and unexpected behavior.
Then in some other
part of the system you use try/catch to prevent the code
from terminating
abruptly. You catch the exception (you should know which
exceptions can be
thrown), and act accordingly. Either closing resources, add
a log message
with debug information, and/or sending an error message to the user.

Try() and Catch() seems neat; but, I've not found it to be

Anyone using it? How?

[PHP] about __get,__set Overloading, read-only properties
Hi. all ,
I got a article from php 5.0 manual's comments. It's useful, offer readonly
properties for classes.
(look at the end of this message for the article )
find out function __construct(), I want to modify $this-id in it , then I
got a readonly Exception (defined in __set function).
Distinctly, a read-only property could not be change via $obj-attribute =
'' ,
but is could be change via $this-id='', inside of class , isn't it ?
How to modify __set function ?
thanks for any advises.
regards!

If you're wondering how to create read-only properties for your class, the
__get() and __set() functions are what you're looking for. You just have to
create the framework and code to implement this functionality.
Here's a quick example I've written. This code doesn't take advantage of the
type attribute in the properties array, but is there for ideas.
?php
class Test
{
private $p_arrPublicProperties = array(
id = array(value = 4,type = int,readonly = true),
datetime = array(value = Tue 02/21/2006 20:49:23,type =
string, readonly = true),
data = array(value = foo, type = string, readonly =
false)
);
//ked add!!!
public function __construct()
{
$this-id = 100; //will get exception
!!
}
private function __get($strProperty) {
//Get a property:
if (isset($this-p_arrPublicProperties[$strProperty])) {
return $this-p_arrPublicProperties[$strProperty][value];
} else {
throw new Exception(Property not defined);
return false;
}
}
private function __set($strProperty, $varValue) {
//Set a property to a value:
if (isset($this-p_arrPublicProperties[$strProperty])) {
//Check if property is read-only:
if ($this-p_arrPublicProperties[$strProperty][readonly]) {
throw new Exception(Property is read-only);
///---note here
return false;
} else {
$this-p_arrPublicProperties[$strProperty][value] = $varValue;
return true;
}
} else {
throw new Exception(Property not defined);
return false;
}
}
private function __isset($strProperty) {
//Determine if property is set:
return isset($this-p_arrPublicProperties[$strProperty]);
}
private function __unset($strProperty) {
//Unset (remove) a property:
unset($this-p_arrPublicProperties[$strProperty]);
}
}
$objTest = new Test();
print $objTest-data . \n;
$objTest-data = bar; //Works.
print $objTest-data;
$objTest-id = 5; //Error: Property is read-only.

don't - let __set() be the policeman it's supposed to be.
either create a private function to initialize values or set
the values directly in the array
private function init($k, $v)
{
if (isset($this-p_arrPublicProperties[$k]))
$this-p_arrPublicProperties[$k]['value'] = $v; }

[PHP] How to new a Object via class name String?
Hi , I'm a freshman in PHP, can anyone give me any advices?
I defied some simple classes, like User, Item...
in a general way ,
$obj = new User();
specially, I need to assign a Object via a class name .
Now , my code :
switch ($className)
{
case User:
return new User();
break ;
case Item:
return new Item();
break ;
default:
break ;
}
I think that It's not a clever job. How to do it skillfully?
Thank you for any advice.
