Re: [PHP] ftp_connect returns false
On Thursday 19 August 2004 13:43, DBW wrote: Just to clarify a point, does it matter where you are coming from and executing the php script? i.e. I am using a browser that is behind a firewall blocks ftp (hence why I am trying to set up this ftp stuff through php). I am pretty sure that it doesn't, since I have used other sample scripts around the web run on their own server and they work fine. Just want to check to make sure this is actually the case. The ftp connection is made from where the php script resides. Which means on the webserver. So if the host has blocked outgoing ftp connections from the webserver you're hosed. That is why I suggested that you try an ftp connection to the webserver itself (from the webserver of course): 1) I'm assuming that your host machine has both the webserver installed (obviously) and that it has an ftpserver (for you put stuff into your webspace). 2) I'm further assuming that your host has not blocked ftp connections coming from localhost Thus if you're able to connect locally then it is a good indication that php's ftp functions are not a fault, and that it is the host's network configuration that is preventing you from making outgoing ftp connections. -- Jason Wong - Gremlins Associates - www.gremlins.biz Open Source Software Systems Integrators * Web Design Hosting * Internet Intranet Applications Development * -- Search the list archives before you post http://marc.theaimsgroup.com/?l=php-general -- /* He that breaks a thing to find out what it is has left the path of wisdom. -- J.R.R.

[PHP] oop too slow
Hi I'm trying my new php5 script, but it takes about 1.2s to generate my page. That is, how my oop model looks like : [category] ||| [photo] [desc] [products] [products] | [product] ||| [photo] [desc] [keys] [keys] | [key] | [values] | [value] Each object gets data from mysql by itself. The generation time of 1 category [30 products, 10 keys, 5 values ~= 300 mysql queries] takes as I said more than a 1s (on quite fast machine). How can this model be improved? Do I create too many objects ? What are the oop solutions for such problem ? I also use an extra table to create many-to-many relation betwean a product and a key. Is this the only way in mysql ?

Re: [PHP] Cannot Load DLLs (WinXP, Apache 2, PHP 5)
I can't get PHP to load php_mysql.dll, required to use the mysql_*() functions. I have tried a variety of values for extension_dir, including C:/php/ext, C:\php\ext, C:\php\, ./ext/, ext/. I have copied php_mysql to all these directories, but it is not loading it. PHP is stored in C:/php, and works perfectly apart from not finding the MySQL dll file. If you could advise me for how to get PHP to load this DLL, I would be very grateful! This was just disussed a few days ago. Copy the libmysql.dll file **that comes with PHP5** into the windows/system32/ directory. New installation instructions exist that recommend never copying any files to the Windows system directory. It's preferred to leave all files in the PHP directory and make it (the PHP folder) available to the systems PATH by editing the appropriate system environment variable. People copy files into the Windows system directory because it's in the PATH so no additional setup is required. Do not fall into this trap. Add the PHP directory to your PATH as doing so will make the world a better place. The updated manual is as follows: http://php.net/manual/en/install.windows.manual.php If setup this way the above problem would not exist, PHP will find libmysql.dll.

It's probably because:

2) the postgres module isn't loaded in the PHP that apache is using
3) the postgres module in the PHP that apache is using is connecting
via a socket instead of a port (or vice-versa)
I think you may have something with the apache module points.
I'll ask if apache has been built or is just the install from
the linux distro. I built apache previously, but I didn't install

If you are doing exactly how it is described in the mail() function documentation and still get that results, that sounds like a mail() function bug dealing with line endings. I have seen people complaining of the exactly the same thing, so you'd better not use the mail() function at all. If you are using sendmail or some equivalente, you may want to try this class for composing and sending messages that comes with a sub-class specialized in deliverying via sendmail. That class also provides you easy control of sendmail options that are more appropriate for bulk mailing. If you do not want to change your scripts much, you can use a wrapper function named sendmail_mail() that works exactly like the mail() function but works directly with sendmail and lets you change tune the options for bulk mailing as it would be useful for you. http://www.phpclasses.org/mimemessage -- Regards, Manuel Lemos PHP Classes - Free ready to use OOP components written in PHP http://www.phpclasses.org/ PHP Reviews - Reviews of PHP books and other products http://www.phpclasses.org/reviews/ Metastorage - Data object relational mapping layer generator http://www.meta-language.net/metastorage.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] oop too slow
When i have many many objects of the same type to build, i do something
like this...
function getEvents($sql = '') {
$events = $this-dbh-query(
SELECT cols, cols, FROM table,table
WHERE blah blah balh ($sql ? AND $sql : ''),'rows_array');
$rv = array();
foreach($events as $event) {
$rv[] = new CalendarEvent($event);
}
return $rv;
}
my event class takes an array of data and uses phps list function to
load its members. In this case, i save 100s and 100s of queries ,
using just 1. Its a massive improvment if it fits your scheme. To get
one event, i create a method called getEvent($id) that is a wrapper to
getEvents, and only uses the first record.. of coarse, there is only
one record.. but ya.. cheers

I have already created a login page for the site so users must log in. The download files are in a directory protected by htaccess which it is my understanding that PHP can go underneath htaccess to get access to the files. My problem is where do I put this directory?

It's probably because:

2) the postgres module isn't loaded in the PHP that apache is using
3) the postgres module in the PHP that apache is using is connecting
via a socket instead of a port (or vice-versa)
I think you may have something with the apache module points.
I'll ask if apache has been built or is just the install from
the linux distro. I built apache previously, but I didn't install
this machine
Write a script with just:
?php

Run it through apache. Look for the postgres module (may be called pgsql).

My problem is where do I put this directory? I was already told to put it outside the web root directory, [..] Both are good methods to protect your files. And yes, you can access your files because PHP is working on the servers side and doesnt need to obey the .htaccess restrictions you defined for user/clients. With .htaccess protection you can access them by yourself later using login/password combination. Outside your DocumentRoot you won't have the possibility and without any help of serverside processes you will not be able to access them.

Re: [PHP] downloading files
You can put the files that need to be downloaded in a directory somewhere outside of the web server root, but in that case your PHP program will need to read the file and print it to the browser, and it will also need printing the HTTP headers: Content-type: application/octet-stream Content-disposition: attachment; file=$filename Content-length: xxx [blank line] Or you can put the files somewhere on the web server tree, protect the directory with .htaccess (username + password), and just put a simple link to those files. When someone will click that link, it will be asked for a username and password in a popup window that the browser will open. If you don't want to appear that window, you can set your server to redirect the user to a php script, for a certain Status code that is generated when authorization is required, and that PHP script can ask nice for a username and password that can be used then by the script to allow access to that file (but this way might be more complicated without real benefits).

Problem with that is it sorts according the results of the recordset range.

What I need is to sort them all by miles first. The only way I know to do that is to do the way I set it up. So if I create an array, sort that array by the miles then use that array. However the array is different that the recordset and thus does not use LIMIT. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Basically, in order for your session to work, you have to let the page

You have visited ? echo $_SESSION['count']; ? pages so far!
=== End of code ===
Looking at this code, there's no link to another page, so there's no
way of letting the web server (and PHP in this case) know what the
session id is. If your php.ini hasn't been changed, you could see the
session in action by adding a link that points to the same page. Say
for example, the name of this file is 'session.php'. Add the
following line to your page:
a href=session.phpSee the session in action!/a
PHP will rewrite this to:
a href=session.php?SID=12345678123456781234567812345678See the
session in action!/a
Clicking on the link will then show $_SESSION['count'] incrementing.
You should have seen something similar even if you have cookies the
first time you start your browser (assuming your only using session
cookies) since PHP hasn't received any session information from the
browser.

Re: [PHP] arrays() current() next() who to use
Vern [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Problem with that is it sorts according the results of the recordset range. For instance: It will show the user 1 trhough 10 sorted by miles then 20 - 30 sorted by miles, however, in 1 through 10 could have a range of 0 to 1000 miles and the next set will have 5 to 200 miles. What I need is to sort them all by miles first. The only way I know to do that is to do the way I set it up. So if I create an array, sort that array by the miles then use that array. However the array is different that the recordset and thus does not use LIMIT. What about this: SELECT * FROM table ORDER BY miles LIMIT 0, 10 Then pass the offset to your query function and exchange it with 0: SELECT * FROM table ORDER BY miles LIMIT $offset, 10 Of course you have to properly validate that $offset is an integer before using it in the query.

When i have many many objects of the same type to build, i do something
like this...
function getEvents($sql = '') {
$events = $this-dbh-query(
SELECT cols, cols, FROM table,table
WHERE blah blah balh ($sql ? AND $sql : ''),'rows_array');
$rv = array();
foreach($events as $event) {
$rv[] = new CalendarEvent($event);
}
return $rv;
}
my event class takes an array of data and uses phps list function to
load its members. In this case, i save 100s and 100s of queries ,
using just 1. Its a massive improvment if it fits your scheme. To get
one event, i create a method called getEvent($id) that is a wrapper to
getEvents, and only uses the first record.. of coarse, there is only
one record.. but ya.. cheers

Hi
I'm trying my new php5 script, but it takes about 1.2s to generate my

That is, how my oop model looks like :

[products]
|
[product]

[photo] [desc] [keys]
[keys]

Each object gets data from mysql by itself. The generation time of 1
category [30 products, 10 keys, 5 values ~= 300 mysql queries] takes
as I
said more than a 1s (on quite fast machine). How can this model be
improved?
Do I create too many objects ? What are the oop solutions for such
problem ?
This is something that I've wrestled with too. If you make each item you
deal with a clean, self-sufficient object, with self-storage, data
hiding
etc, it is inevitable that you run into this problem. It is a symptom of
a
fundamental clash between Relational DB and OO points of view. The only
trick I have found to work around it that is OO-clean is to use factory
methods or objects that create multiple objects from a single DB query,
so
as well as having a 'get' method that populates an object from a DB,
make
another means of creating an object from local data that has been
obtained
from a larger query that returned sufficient values to populate multiple
items.
I also use an extra table to create many-to-many relation betwean a
product
and a key. Is this the only way in mysql ?
[product]
|
[product_id, key_id]
|
[key]
Yes, that's the correct way to represent a M:M relation in a relational
DB.
The join table is an artefact of a relational model, rather than an OO
one,
so the answer is to hide the existence of this table within the objects
at
either end - so have product and key objects, but not product_key
objects.
Each object should have a method that retrieves instances of all the
related
objects of the other kind. This is really a different manifestation of
the
first problem.
Ultimately the trick is to create separate factory objects or
higher-level
methods inside the existing objects that can create multiple instances
from
a single database query. Having said that, it's difficult to spot the
best
places to do this. For example, you might normally create multiple
product
objects from an array of database IDs like so:
foreach($productids as $id)
$products[] = new product($id);
You can see that this would cause a query for each instantiation.
With a product factory class, you might do this instead:
$products = product_factory::get($productids);
Which achieves the same result, but using only a single DB query (hidden
inside the factory class, which does NOT call the product class in the
same
way!). The next problem is keeping your product_factory and product
classes
in sync - I'm sure there must be a nice pattern to deal with that
somewhere.

Thanks a lot, after your replies I made a little google search on 'factory

Re: [PHP] arrays() current() next() who to use
The miles are being caluculated during the loop that is created using the
recordset not in the database.
First I create a do..while loop to get the miles
do {
$k = 0;
//SET FIRST ARRAY OF ONLINE USERS AND CALCULATE MILES
do {
//GEOZIP
$zip2 = $row_rsUSERIDID['zip'];
$coor1=mycoors($zip1);
$coor2=mycoors($zip2);
$line1=split(\|,$coor1);
$line2=split(\|,$coor2);
$totaldist=distance($line1[0],$line1[1],$line2[0],$line2[1],mi);
//SET NEW ARRAY WITH MILES
$z['username'][$k] = $row_rsUSERIDID['uname'];
$z['distance'][$k++] = $totaldist;
} while ($row_rsUSERIDID = mysql_fetch_assoc($rsUSERIDID));
//SET NEW ARRAY
$z['user'] = $z['username'];
//SORT BY DISTANCES
natsort ($z['distance']);
reset ($z['distance']);
//DISPLAY USER INFORMATION SORTED BY MILES
foreach($z['distance'] as $k = $v){
$newuser = $z['user'][$k];
echo $newuser . - . $v . br;

} while ($row_rsUSERIDID = mysql_fetch_assoc($rsUSERIDID));
I now what to display this info 10 records at a time.

However this is resulting in an Parse error on the foreach line:

i must put \n after the Firstname. But PHP actually reads \n so when
