[PHP] FW: [NEWBIE GUIDE] For the benefit of new members
= Please feel free to add more points and send to the list. = 1. If you have any queries/problems about PHP try http://www.php.net/manual/en first. You can download a copy and use it offline also. Please also try http://www.php.net/manual/faq.php for answers to frequently answered questions about PHP (added by Christophe Chisogne). 2. Try http://www.google.com next. Searching for php YOUR QUERY may fetch you relevant information within the first 10 results. 3. There is a searchable archive of the mailing list discussion at http://phparch.com/mailinglists. Many of the common topics are discussed repeatedly, and you may get answer to your query from the earlier discussions. For example: One of the repeatedly discussed question in the list is Best PHP editor. Everyone has his/her favourite editor. You can get all the opinions by going through the list archives. If you want a chosen list try this link : http://www.thelinuxconsultancy.co.uk/phpeditors/ (contributed by Christophe Chisogne). 4. Not sure if PHP is working or you want find out what extensions are available to you? Just put the following code into a file with a .php extension and access it through your webserver: ?php phpinfo(); ? If PHP is installed you will see a page with a lot of information on it. If PHP is not installed (or not working correctly) your browser will try to download the file. (contributed by Teren and reworded by Chris W Parker) 5. If you are stuck with a script and do not understand what is wrong, instead of posting the whole script, try doing some research yourself. One useful trick is to print the variable/sql query using print or echo command and check whether you get what you expected. After diagnosing the problem, send the details of your efforts (following steps 1, 2 3) and ask for help. 6. PHP is a server side scripting language. Whatever processing PHP does takes place BEFORE the output reaches the client. Therefore, it is not possible to access users' computer related information (OS, screen size etc) using PHP. Nor can you modify any the user side settings. You need to go for JavaScript and ask the question in a JavaScript list. On the other hand, you can access the information that is SENT by the user's browser when a client requests a page from your server. You can find details about browser, OS etc as reported by this request. (contributed by Wouter van Vliet and reworded by Chris W Parker.) 7. Provide a clear descriptive subject line. Avoid general subjects like Help!!, A Question etc. Especially avoid blank subjects. 8. When you want to start a new topic, open a new mail composer and enter the mailing list address php-general@lists.php.net instead of replying to an existing thread and replacing the subject and body with your message. 9. It's always a good idea to post back to the list once you've solved your problem. People usually add [SOLVED] to the subject line of their email when posting solutions. By posting your solution you're helping the next person with the same question. [contribued by Chris W Parker] 10. Ask smart questions http://catb.org/~esr/faqs/smart-questions.html [contributed by Jay Blanchard) 11. Do not send your email to the list with attachments. If you don't have a place to upload your code, try the many pastebin websites (such as www.pastebin.com). (contributed by Burhan Khalid) Following these guidelines will ensure that you get effective responses from the list members. Otherwise, your questions might not be answered. === Hope you have a good time programming with PHP. === -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

foreach ($rsses as $rss) {

However, why not use for()?
for($i=0;$i10;$i++) {
// do stuff

My best guess is that it's being converted by Apache using mod_rewrite. For one of my websites, for instance, I have mod_rewrite convert /op_ed/123 to /op_ed/index.php?id=123. It's more search engine-friendly, for one, and an easier structure to remember for non-techie folks.

RE: [PHP] Upgrade PHP 4.3.4 to PHP 5.0.3 (Windows 2k IIS5), I recieve a Blank Page and Session errors
The $_SESSION['sitedoc'] was not initialized because I use
$_SERVER[PATH_TRANSLATED] to make the requires for diffrent files. In
these file I initialized this $_SESSION varibales. I already took care for
this ploblem (in PHP5 you have to replace it for ORIG_PATH_TRANSLATED).
But I still have the blank page, with no error or wrnings.
The only thing that look strange is that the session files in sessiondata

Hi, I'm trying to upgrade the PHP version of my dev enviroment.
After installing PHP5 I've just recieve a blank page. I activated the
error
log of PHP and recieve a couple of errors like this one:
[09-Feb-2005 13:38:20] PHP Notice: Undefined index: sitedesc in
c:\Inetpub\wwwroot\Inpae\admin\lib\headerFooter.php on line 40
All related to $_SESSION, like the values are not set (sitedesc is one of
the indexes of the variable $_SESSION)
But when you first start a session, a totally NEW session, is
$_SESSION['sitedoc'] initialized?
I assume not.
Your problem code looks something like this:
?php
session_start();
if ($_SESSION['sitedoc']){
//whatever;
}
?
PHP is notifying you that there is NO session index named 'sitedoc' yet,
but you're trying to read it and use the value -- the value that doesn't
exist.
You'll need to get in the habit of writing (and re-writing) code like this:
?php
session_start();
if (isset($_SESSION['sitedoc']) $_SESSION['sitedoc']){
//whatever
}
?
You may also re-structure your code a bit if 'sitedoc' can take on several
values, so it ends up being more like:
?php
session_start();
if (isset($_SESSION['sitedoc'])){
if ($_SESSION['sitedoc'] == 'whatever'){
}
elseif ($_SESSION['sitedocd'] == 'something else'){
}
}
?
The point is that you shouldn't be reading session variables that were
never set to any value at all in the first place.
Sure, PHP will initialize them to 0 or '' or false, but the point here is
to catch typos where you have:
if ($_SESSION['sietdoc']){
}
else{
}
If you RARELY expect 'sitedoc' to be a TRUE value, and you don't do a lot
of unit testing, a typo bug like this could go undetected for a long
time.
The PHP Notice warns you about things like this by not notifying you when
you try to read a variable that hasn't been set.
Notice: C:\Inetpub\wwwroot\Inpae\lib\include.php line 15 - Undefined
index:
SCRIPT_NAME
Notice: C:\Inetpub\wwwroot\Inpae\lib\include.php line 15 - Undefined

See above.

'/config.php' (include_path='.;c:\php5\pear')
config.php is not in the same directory as your script, nor in the PEAR
library. It is, probably, in Inpae\lib\ and you need to change your
include_path setting in .htaccess or in the script or somewhere to have
that directory in your include path.

Pretty funny http://bbspot.com/News/2000/6/php_suspend.html http://bbspot.com/News/2000/6/php_suspend.html Topeka, KS - High school sophomore Brett Tyson was suspended today after teachers learned he may be using PHP. A teacher overheard him say that he was using PHP, and as part of our Zero-Tolerance policy against drug use, he was immediately suspended. No questions asked, said Principal Clyde Thurlow. We're not quite sure what PHP is, but we suspect it may be a derivative of PCP, or maybe a new designer drug like GHB. php_logoParents are frightened by the discovery of this new menace in their children's school, and are demanding the school do something. We heard that he found out about PHP at school on the internet. There may even be a PHP web ring operating on school grounds, said irate parent Carol Blessing. School is supposed to be teaching our kids how to read and write. Not about dangerous drugs like PHP. In response to parental demands the school has reconfigured its internet WatchDog software to block access to all internet sites mentioning PHP. Officials say this should prevent any other students from falling prey like Brett Tyson did. They have also stepped up locker searches and brought in drug sniffing dogs. Interviews with students suggested that PHP use is wide spread around the school, but is particularly concentrated in the geeky nerd population. When contacted by BBspot.com, Brett Tyson said, I don't know what the hell is going on dude, but this suspension gives me more time for fraggin'. Yee haw! PHP is a hypertext preprocessor, which sounds very dangerous. It is believed that many users started by using Perl and moved on to the more powerful PHP.

For each key/value pair it will create a variable in the current symbol table.

If your mysql server has access (or can have access) to the directory

fast.

Betreff: [PHP] export mysql to csv prob
hi
i have a script that exports the result of a mysql query to a csv file
suitable for downloading
the code looks like
$result = mysql_query(select * from user,mjp1,mjp2,mjp3,mjp4);
while($row = mysql_fetch_array($result)) {
$csv_output .= $row[userid] $row[firstname] $row[lastname]\n }
header(Content-type: application/vnd.ms-excel);
header(Content-disposition: csv . date(Y-m-d) . .xls); print
$csv_output;
this works fine, except that when i expand the line $csv_output
.=$row[userid] $row[firstname] $row[lastname] $row[anotherfield]
$row[anotherfield] ...\n} -to include an increasing number of fields, it
tends to bog down the speed at which the $csv_output file can be printed.
when i have this line output 30+ fields for each row, wait time for output
file generation is almost 4-5 minutes.
is this the most efficient way to do this? i'd like to be able to generate
the file as quickly as possible.
thanks

[PHP] [Fwd: Re: [PHP-WIN] Re: SESSION]
Please send responses to the newsgroup. I am usually happy to help you out, but I do need to keep things organized / slightly sane on my end :) The short answer to your question below: yes you can use Word with PHP and depending on your needs this might happen on the server or you might just send a Word document to a browser with the correct mime-type. Based on what you say in your message what you want to do is read the file's contents on the server side. You don't even need to open Word to do this. Then when you get the file contents you can send the MIME header and the content of the file to the browser. Note that this doesn't *force* the user to open the file through Adobe etc. but it gives the browser an idea of what to do with the file and gives the user that option. Oh, and be careful which files you decide to make public and be *especially* careful which files you allow people to edit and put on the server. You probably already know that, but it doesn't hurt to be reminded from time to time :) Original Message Subject: Re: [PHP-WIN] Re: SESSION Date: Fri, 11 Feb 2005 11:43:24 +0530 From: Vaibhav Sibal [EMAIL PROTECTED] Reply-To: Vaibhav Sibal [EMAIL PROTECTED] To: php php-windows@lists.php.net, Jason Barnett [EMAIL PROTECTED] References: [EMAIL PROTECTED] [EMAIL PROTECTED] Thanks Jason ! It'll be great if you could also tell me whether I can launch applications like MS WORD using COM or any other technology.

The only thing to be taken in mind is that the client does not have a PHP parser installed and is not running a webserver either. The file list comes from the server only, which is actually running the webserver and the PHP parser also. ! Please provide some insight on this.

Re: AW: [PHP] export mysql to csv prob

this works fine, except that when i expand the line $csv_output

$row[anotherfield] ...\n} -to include an increasing number of fields, it
tends to bog down the speed at which the $csv_output file can be printed.

is this the most efficient way to do this? i'd like to be able to
generate
the file as quickly as possible.
Since you don't really care about the individual fields, and you are just
dumping them all out anyway, this might be faster:
$cvs_output .= implode(',', $row);
And, actually, there's no real reason to build up this HUGE string in PHP.
Just spew as you go:
$result = mysql_query(select * from user,mjp1,mjp2,mjp3,mjp4);
header(Content-type: application/vnd.ms-excel);
header(Content-disposition: csv . date(Y-m-d) . .xls);
while($row = mysql_fetch_array($result)) {
echo implode(',', $row);
}
Note that if you ever embed a comma in your data, then you will be
generating invalid CSV...

Actually, there's probably a third category: Those who don't even really own their own machines any more because they got root-ed. :-v I know you're trying to cheer me up, but this isn't helping! ;-) I have this theory that if what you're trying to protect is important enough, somebody will get through the security barriers eventually. That goes double for the internet. A good point that I've failed to bring up is the question How secure do you need it to be?. I think that's an important consideration. Your three groups sound quite accurate, but my big problem is that when a program _has_ to do these things, I'm left in group #2, because I can't find any tried-and-tested methods. This is not usually the case with PHP, the community always seems to provide good solutions. I'm left in group #2 until I've become an expert in this myself, several unpaid years into the future... Webmin is a common tool, and if their security measures don't hold up, then we're in big trouble. I believe they're using PAM somehow, I'll look into that. Until then, it's a sudo scheme.

But, I was wondering, if is possible this scenario: marketing person zip images and csv file together, then in admin area uload zip file to server, and php then unzip file and do the job.

Re: [PHP] Uploading products in database using zip file?
One more thing marketing person use Windows and he will probably use Winzip. Is this still ok, or it's better to use some other application? Hi, right now in my firm, to upload new products to web site, marketing person has to, in admin area, upload csv file (then php read content and store info in DB), and then ftp all images in temp directory. And then, using other php script, resize images and put them in product_images directory. Whole process works just fine. But, I was wondering, if is possible this scenario: marketing person zip images and csv file together, then in admin area uload zip file to server, and php then unzip file and do the job. Actually, instead doing two operations (upload csv file and ftp images) he has to do just one thing: upload zip file. ??? Or, if somebody has an idea about this whole process?

First of all I would suggest using 7zip on Windows. Its usage is 100% free (you can of course donate to the project if you feel it is worthy). Your sales guy can then create zip's / tgz's / whatever archiving scheme supported by 7zip.

But, I was wondering, if is possible this scenario: marketing person zip images and csv file together, then in admin area uload zip file to server, and php then unzip file and do the job. Sure... PHP can unzip the archive to a temp directory. Then you glob the files in this temp directory and have PHP perform the action(s) matching that type of file. Rinse and repeat for images. Alternatively you can have PHP try checking the contents of each individual file to guesstimate what type of file it is and handle it accordingly. If you go this route it may also be worthwhile to check the file's contents for possible XSS exploits, or PHP code, or ... Even if the images are stored in a database / other server this shouldn't be too tough for PHP to handle. :) Actually, instead doing two operations (upload csv file and ftp images) he has to do just one thing: upload zip file. ???

You usually would use quotemeta on data coming from the database, or the user, or externally, or, errr, basically things you haven't typed in to PHP, that you need to pass into Regular Expressions.

Hello,
Is there anyway to retrieve the properties from a pdf file using php?
When you right click on a pdf file in windows you can see the title of
the file and you can change this property there also.
I wrote a php page that lists all files in a certain directory. I want
to be able show the actual title of the document instead of just the
file name.
I have searched the manual and google, everything that comes up refers
to generating pdfs on the fly, not working with an already made pdf.
Thanks in Advance,
Jason Motes
If you study the structure of pdf in a text editor, you'll notice that it
is quite readable. If you go to the end of a document, prefferably a small
one, you will see the trailer. Here is al list of all bytepositions of the
objects the pdf document contains. These objects can be images, text, page
descriptions, page groups and so on. There can also be a reference to the
properties of the document wich can contain creator, author, title etc. It
is easy to read the objects, but to change them can prove rather
difficult, as you will need to update the trailer informaition with new
byteposition for all objects that comes after the properties (hard to
explain), unless you keep the new info the same length.
But as you only need to extract the title you can do this with a simple
regexp.
while(filelistingstuff) {
$document = file_get_contents($pdf);
if(preg_match(/\/Title\s\((.*?)\)/i,$document,$match)) {
$title = $match[1];
} else {
$title = $filename;
}
}
Hope this helps.

[PHP] Minimalist permissions
Hi, Please forgive me if this specific question has already been addressed, but I'm doing tests to figure out what are the minimal permissions I can give on my files and folders for a PHP application and I just can't find it (even by searching this list). Feel free to redirect me to existing documentation that I woule have missed, if needed. My config: Apache2 on RHEL, php-4.3.2-19. The server runs as apache.apache. I have a test server and a prod servers. On the test server, one developper accesses the files directly in his home (userdir activated). On my production server, the application is located in a subfolder of the document root (/var/www/html/) and files are tarred on the test server, copied using sftp (to my user account) mv'ed into /var/www/html and then untarred. This server is not shared by external users, so it is usually only root that can put content in the DocRoot. According to my tests, we need read permissions for php files to be processed by apache, and we need execute (and read) permissions on direcories.For directories in which php uploads (images) or create (pdf) files, it needs write permissions on the directory. I'm curious about the reason why it needs execute permissions on directory. According to the documentation, 'x' on directories allows to 'search' a direcory. Isn't 'r' enough? That allows php to read the directory listing... However, this is not my main concern... So here it is: If the needed permissions for standard PHP files and directories are 'r' on files and 'r-x' on directories, how can I set my umask so that files and directories are always created as such? I looked up 'man umask' and it seems to treat files and directories the same way. Maybe that is impossible, but I logged in via FTP to a server of a web hosting company, and it implements just this: creates directories as rwxr-xr-x and files as rw-r--r--. Another thing... how should I configure ownership on the files? root as owner, apache as group and no permissions for others? Thanks for taking the time to read such a long post.
