Re: [PHP] PHP textbook suggestions?
I'd still like some actual recommendations for a good book for beginners. My PHP and MySQL for Dynamic Web Sites: Visual QuickPro Guide has already been mentioned by someone and gets good reviews. If you want something more basic, I wrote PHP for the World Wide Web: Visual QuickStart Guide for the non-programmer. It goes at a much slower pace but obviously doesn't cover as much. Although neither is technically a textbook, both are used as textbooks in high school and college classes. For a recommendation without the self-interest, the Thomson and Welling PHP and MySQL something something something (Sams) is a very good book (I forget the title, but it is good and thorough). Whatever you look at, make sure you get the latest editions. I know that Amazon doesn't necessarily offer up the latest edition of a book, so you sometimes need to click on All Editions to see if it's been updated.

Re: [PHP] __construct __destruct in PHP 4
I have been trying going thru the PHP manual to find if there are any equivalent to the __contruct and __destruct in PHP 4, but I cannot find any solution for this part. I know it was introduced in PHP 5, but as __sleep and __wakeup exist in PHP 4 already I was hoping there is something like __init and __die in PHP 4 :-) In PHP 4 the constructor has the same name as the class (like C++).

[PHP] [JOB] PHP Book Tech Reviewer
I'm currently writing the second edition of my PHP Advanced book and need a technical reviewer. It is a paid job and some people think it's interesting/looks good on a resume/etc. Obviously you'll need to be an expert in PHP and pay close attention to detail. My definition of advanced for this book means: - OOP - Doing what you already do but better and faster - Tangential topics (GD, PDFlib, CLI, PEAR, XML, Ajax, MySQL, E- Commerce, other buzzwords).

Re: [PHP] php/mysql/phpMyAdmin on an iBook?
I'm thinking of getting an iBook for reasons not really to do with webbing but really need to do occasional php/mysql stuff to justify the expense. I believe that they all come with an Apache testing server installed and wondered if anyone had any success with getting php/mysql/phpMyAdmin working on one of these machines. No problem at all.

Re: [PHP] Clear POST variables
How do I clear out the POST variables, or the variables that I have set from the POST variables, so that when the page is refreshed it will not resubmit. I have tried unset() and have tried to set it to and empty value, but it doesn't seem to work. You can clear out POST by doing this: $_POST = array(); But that won't do anything in your case because every time the page is refreshed the form is resubmitted (and POST is repopulated). You need to find a way to ensure unique entries in the database. One option is to store a hidden, random value in the form, like a timestamp or the md5() of a random value. Then store this in the db, along with the other data. Put a unique index on that column so that the same random value cannot be inserted multiple times. (In other words, the form would need to be reloaded, then resubmitted for the data to go into the db.)

Re: [PHP] LIMIT?
I have a news page which is getting quite long now and I would like to split the news to two pages. Now I have one SQL query for all the rows and I think I could use LIMIT to limit the results but how to limit the results for example to 15 rows for page one and from 16 to the last on second page? Number of rows increase daily. One page one there's headline and short summary and the second page should be archive with only the headline so all remaining rows can be printed to one page. Something like: SELECT * FROM `x_news` LIMIT 0 , 15 but how to do the archive page SELECT * FROM `x_news` LIMIT 16 , xx? What you're describing is called pagination. There are examples online. Basically you just need to pass to the second (and other) pages the LIMIT values (16 and xx above).

I have a project where I'm being forced to do some ASP.NET development, which I've never touched. I need to learn it fast. Nobody has enough money to make me do ASP again. ASP.NET is leaps and bounds better than ASP. I would never use ASP but do do the occasional ASP.NET job (although PHP is my primary and preferred language). I'm not sure about learning ASP.NET fast, but you should start by: - Picking a language to use. VB Script and C# are the biggies. IMHO VB Script is easier, C# is better. - Picking an IDE. WebMatrix is free and easy to use. Visual Studio .NET is expensive and not easy to use but potent. - Knowing what database you'll be using. Probably Access (which totally sucks) or SQL Server (which kind of sucks). Other than that, I personally always start with a good book. If you do that, pick a book that uses the same language and IDE that you'll be using. Also, in my opinion, having a good knowledge of how to create a dynamic Web site helps when going from PHP to ASP.NET. If you know what the program must do in terms of functionality, protocol, etc., then it's mostly a matter of picking up the right syntax. I found that ASP.NET is the opposite of PHP: doing something simple is ridiculously hard but doing something kind of complex is pretty simple.

Re: [PHP] Fixing ID's in mySQL Table
Is there a way to fix ID sequence in a MySQL table using PHP? Basically I have some tables with a lot of records, 1000 to 5000. ‘ID’ is the Primary Key column in these tables, and at the time the code was originally written, there weren’t much verification of data being input going on. Thus a lot of junk records were being let in, which had to be deleted at some point or another. Now the ID sequence is all screwed up. It’s not in sequence anymore. You may not like this answer but you shouldn't fix this. Primary keys, by definition, should never change. Their purpose is to uniquely refer to a record. If you change the primary key of a record, then you've undermined this purpose. If you have holes in your sequencing, this isn't a problem either, as how the records are stored in the database is completely meaningless. If you need the records to be listed in some sort of order, you should add another column or table that manages that. But leave the primary key alone.

Re: [PHP] No forums?
One of the fallacies in your argument is that the lack of an official forum on php.net implies such distaste for message boards. I don't have a big screen TV but I have anything but distaste for them! Well, let me give you a different example. I don't have a TV at all, even though I could buy one. Knowing this, would you assume that I don't like watching it? No, I wouldn't, as my point is that the lack of something doesn't imply _any_one_thing_. There are many reasons why something may or may not exist. Assuming that there is such distaste for message boards is fallacious (as would be my assuming you don't like TV). The same thing with forum. It's a usual feature, just like website is. Would you be surprised if PHP had no website? Yes, I would, particularly as I've been going to it for years. Finding out that PHP had no website would definitely mess with my perception of reality. But I disagree with your theory that having a forum is implied by the technology. PHP is open source, so the fact that ANYBODY freely supports it in any way is just plain nice. Also, you should realize that your question could be rephrased as Why hasn't someone else done all this extra work (creating and managing a forum) because I would prefer it? Are you saying that I'm the only PHP user that might like discussing things on a forum? I'm pretty sure I didn't say that but I'll have to check my notes. I'm saying that you seem to be incredulous over the lack of something which you think makes sense. But my point is that there can be any number of reasons why php.net does not have a forum so the lack need not be ironic. In fact, that lack may even make sense (at least to those that run the Web site). Besides, you're implying that maintaining forum is extra work, while maintaining mailing lists isn't. Extra work for extra users you can live without, eh? Eh? What? Well, it IS extra work. The mailing list exists and, many believe, work just fine. Doing more than what is currently being done is extra, right? Or more? I'm almost positive about that.

Well, the stupid/obvious question is: are you checking $_COOKIE

Sixth, can __you__ actually connect to your remote server from Windows so that you can open a networked file? Um, I'm guessing not. Seventh, many FTP applications let you set an external text editor.

Re: [PHP] OT Re: [PHP] can I compile php source
While Yes may be a technically accurate answer to a question like Can I ... or Can anyone ..., a couple of points must be acknowledged: 1) Such an answer doesn't help the original poster. Period. And the purpose of a resource like this is to help, right? Even a RTFM or search Google at least gives the user __something__ to work with (and the lesson there being that if they read the manual or search Google, they'll quickly find answers). If your argument for answering Yes is that you're teaching the user to ask questions the smart way, then why not answer their intended question AND refer them to the smart questions page? Do you honestly think people are learning __anything__ when you reply with a Yes? Moreover... 2) It's commonplace in human discourse to attempt to address the *intent* of a person's question rather than the literal question itself. If you were helping a friend re-shingle a roof and they said Can you hand me that hammer?, hopefully you would actually hand them the hammer, not say Yes. They are many colloquialisms in languages--like when someone says What's up?--and it's just obstinate not to recognize them as such and respond accordingly. Finally, if you don't agree that Yes isn't helpful and that it's an inappropriate answer anyway, how about this: such emails are a waste of resources. It's a waste of the time (.1 nanoseconds or whatever) it took you to write. It's a waste of bandwidth (at a few bits a pop). It's a waste of everyone's time in reading and deleting such emails (another second). And it tends to start a sequence of even longer, off topic threads such as this one. So, seriously, if you don't feel like helping or you don't believe that a message should be posted here because it's off topic or you don't believe that a question was phrased properly, wouldn't it be better for everyone if you just didn't respond?

Re: [PHP] Object oriented??
Yes of course...but was confused since some says it is so and some says it is not...So thought of asking the pros.. It is. PHP4 had limited support for OOP, though it was quite usable. PHP5 goes further and provides pretty much everything else. See the documentation on php.net for the complete language reference. I guess this is where the OP's confusion stemmed from (Robert said Yes, I said No)! A liberal definition of OO is An adjective applied to any system or language that supports the use of objects, under which PHP would qualify. But, in strict OO languages, everything must be done using objects. You can't even do a simple Hello, World without them (I could be wrong on this, of course). With that understanding PHP would not be OO. So, in short, PHP __supports__ objects but does not __require__ them. There's a good chance that 20 people will chime in now, with their own corrections.

Re: [PHP] Extra byte added to PDF streaming file
I've seen cases where extra buffer content gets added to the downloaded file. The problem was fixed by deleting any existing buffer before sending the file to the client. Not sure that will solve the problem but it's worth a shot. How does one delete an existing buffer? ob_end_flush();? ob_end_clean() For future reference, you should normally reply to the entire PHP list, not just to the person replying to your message.

Re: [PHP] Extra byte added to PDF streaming file
It appears as though some readers (such as adobe acrobat) can read this file fine yet others (such as the program gv in *NIX) cannot read it. The reason for this is that somehow a hex 0A is added before the inital %PDF-1.2 which marks the start of the PDF file causing some readers to not recognize it as a PDF file. Is there anything in this code which could possibly (always) cause an extra byte (0A) to be added before the real start of the file? And no, the file is not corrupted (I've already tried that) - this only happens when it goes through this script, and not loaded directly as example.com/file.pdf. I've seen cases where extra buffer content gets added to the downloaded file. The problem was fixed by deleting any existing buffer before sending the file to the client.

Re: [PHP] viewing PHP files on Internet Explorer 6
Rocky, First off, when working with mailing lists like these, you generally should reply to the entire group, not to an individual person. Doing so takes the burden off of the person who initially replied to you. Moreover it means that you won't have to wait for that one person to get back to you. Thanks Larry, but how do i save my php files to http://localhost? I don't understand if this is a subdirectory in apache or not. You don't mention your OS but I assume it's Windows. I forget the details and it depends upon your installation of Apache but you'll want to save your files in a location like C:\Apache\www. You can always check the Apache documentation for assistance on things like this but it should be a 'www' folder. Because when i do access the php scrips via URL (e.g. http://localhost/test.php) i get an error message saying the page does not exist. It is currenly saved in a regular folder away from apache. Yeah, you need to place the files in the Web root directory.

Re: [PHP] Is Function Constants the Correct Term?
I have been experimenting with defining functions as constants. Below is what I am using to test Function Constants: pre ? define(LOGIN,user); define(PASS,pass); define(DB,mysql); define(DBLOGIN,dblogin(LOGIN,PASS,DB)); This is simply not allowed. see: http://php.net/define Can you elaborate on what is not allowed? Are you saying defining function constants are not allowed or are you saying redefining constants are not allowed? I believe the answer is that both concepts are not allowed. Constants, by their very definition, cannot be redefined (except for magic constants, which is a different thing). Also, constants must be set as scalar values. PHP doesn't support function-like macros as you might have seen in the C preprocessor. This is all in the PHP manual, under define() and constants.

Re: [PHP] Re: PHP SESSION DURATION.....
Correction: I meant to say: Are session variables stored server-side or client-side like cookies? The session data is stored on the server. The session cookie (if there is one) is stored in the browser. How do I go about making a session last longer that the duration of the browser? Set the expiration on the session cookie so that it's a month from now, using the set_session_cookie_params() function. Also, force the users to accept cookies (somehow). Then change the garbage collection so that it won't trash session data for at least a month. Considering how inefficient all of that is, you might be better off storing the data in a database instead of a session and then storing the database record ID in a cookie in the browser. There are some serious security considerations here but it will get your results and won't rely upon PHP's sessions. Again, this isn't ideal but it's a start...

on the search_results page, what happens is:

elements, and count() to count the number of array elements
-then i use a for loop to cycle through the list of array elements and
run a sql query to search through a table for any matches to a
particular array element. the for loop looks like
//for loop that cycles through elements in an array, and searching
through a mys
ql table for matches
for($j=0; $j$count_elements; $j++)
{$sql.=and columnname like '%keywords[$j]%' or columnname2 like
'%keywords[$j]'
or columnname3 like '%keywords[$j]%'...';}
i think this is technically working, since it's not giving me any
errors, however it basically slows down searches to the point of
unusability.
If you are using MySQL, look into FULL TEXT searches. MySQL 4 also has
a binary mode which is pretty good. Make sure you've indexed your
columns as well.

And I try to display it in the table using this : input name=email_1 type=text id=email_1 size=50 value = ? echo $email_1; ? if I try to echo the variable $email_1, I get the correct value i.e. thisisa long e-mail address /// However when it comes to displaying it using the table all I get is the thisisa . It simply avoids the spaces. Can anyone tell me why this is happening..?? I am sure it is something pretty minor but I just cant seem to get it right. You need to quote your value attribute.

Re: [PHP] mysql_real_escape_string
The following function is from Larry Ullman's PHP and mySQL on page 217 - script 6.8 - in which there is a connection to a mySQL database using PHP. My question is that I'm not sure of the global variable $dbc. Hello Anthony, The mysql_real_escape_string() requires a connection to the database. The connection identifier is defined in another script so it's brought in using the global statement.

Re: [PHP] Installation for OS X
Does anyone know of a good installation kit like FoxServ, phpTriad, etc for Mac OS X? I want a quick solution for adding MySQL, GD, phpLib support for my mac. Follow Marc's instructions at http://www.entropy.ch/software/macosx/php/ He provides a compiled version of PHP that includes MySQL support, GD, and much, much more.

Re: [PHP] php.ini
Does the php.ini file always go in the same place no matter the OS? I did a locate in the shell, and nothing came up. I could find .ini files, or php. files, but no php.ini files. In all likelihood, you don't have a php.ini file on your computer, which is why searching for it using conventional methods won't help. To create a php.ini file, you could download the PHP source code, take its php.ini and drop it in /usr/local/lib Larry -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] RedHat
Where would I go on the redHat site to ask when they are going to upgrade to PHP 4.3 and MySQL 4.x (now in production). Our CS dept. won't install them for me until RedHat bundles it. I'm using RH 7.3. This question would probably be best directed towards: 1) The RedHat site 2) A RedHat newsgroup 3) A RedHat mailing list 4) A RedHat forum 5) A RedHat __, not the PHP general mailing list (since your question concerns RedHat packages). I expect that a RedHat support would be much more qualified to answer this question and your original one (when they'll upgrade).

Re: [PHP] Session Theft
i just want to figure out a way by which i can stop session theft.i thought if i can get something from user end that is unique for that user.for e.g. his/her IP .but it will not work when they are behind firewall.they will be assigned same IP.is there a way for me to get the IP (e.g.202.202.202.202 thats just an e.g. ) plus computer ip(192.168.0.1 e.g.) i saw once a java chat server do this.if we can do this then it will help us (SOMEWHAT). You could store the HTTP_USER_AGENT in the session when it starts. Then compare the browser being used against this stored value on subsequent pages. HTTP_USER_AGENT won't always be unique and it's not foolproof but it is a little extra security with minimal effort.

Re: [PHP] uploading large files through php
The problem that I am facing is that I can get the script/browser/php to pass such large file. I have modified the upload_max_size variable in php.ini to be larger the 60Mb but this still does not help! Is there any hard limitation that I am unaware of? You'll probably need to adjust the following: max_execution_time = 30 ; Maximum execution time of each script, in seconds max_input_time = 60 ; Maximum amount of time each script may spend parsing request data memory_limit = 8M ; Maximum amount of memory a script may consume (8MB) ; Maximum size of POST data that PHP will accept. post_max_size = 8M Larry -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] ob_start problem
Warning: ob_gzhandler() [ref.outcontrol]: output handler 'ob_gzhandler' cannot be used twice in /blahblah/includes/bottom.inc on line 25 I can't speak as to why this would only happen occasionally, but I believe that you should comment out the output_buffering line in the php.ini file when using the ob_gzhandler function. Or so says a user-contributed note in the PHP manual... Larry -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] upload files and file types
hi there , i was wondering on security of file uploads , i am currently using the pear uploader class , i can check for allowed file extensions , but it doesnt seem to check for file type , i can currently rename say an image to zip and it uploads , is there anyway a hacker could rename an executable to a zip and able to upload it and execute it ? I can't address your specific question but here are a couple of recommendations: -Rename the uploaded file so that the user won't know what it's called on the server. -Store the file outside of the Web directory so it's not accessible via HTTP.

Re: [PHP] Separators in variable values causing MySQL commands to fail
OK, I can bypass my oversight by stripping out apostophes from the variable values. There has to be a better way please. Turn on Magic Quotes GPC or use the addslashes() function. Or, if you want to be more precise and MySQL-specific, use the mysql_escape_string() or mysql_real_escape_string() functions.

Re: [PHP] Running DB on different server
Can the DB be on a different server than the page server? Yes. For example, with MySQL, you just need to create a user with permission to connect from a remote computer by setting the appropriate host value.

Re: [PHP] time() question
Is there an easy way to display the epoch time given by time() in a human readable format? Basically, if I do $time = time(); and the insert that data into my mysql database and then pull that information out again how do I make it look like 2003-03-13 or a variant of that? If you are pulling a date/time out of a MySQL database, use MySQL's DATE_FORMAT() function to format the value. For that matter, you can use MySQL's NOW() function (or others) when inserting the time. Otherwise, just in PHP, you can use the DATE() function to format dates.

Re: [PHP] Browser Sniffing
I know, it can't be done in PHP. That's not exactly what I'm here for. I have a client who would like to redirect people to a polite 'upgrade your browser' page whenever people visit his site (which has been developed in PHP no less). My question here is, how can I make this so that regardless of what URL someone comes in to, it will always run the sniffer prior to loading the actual URL they visited? In other words, whether the visitor comes to the main url (http://www.site.org), or whether they are going to a specific link (http://ww.site.org/seethis/), the client would like the sniffer to check them all. I know I can stick the whole javascript sniffer into each and every file, but that's just not efficient. Being that this site was created in PHP, I can very easily stick an 'include' in each file to include the javascript piece, however how can I use the results of that javascript piece inside PHP to then do a Header(Location...) type thing? Can I even do that considering that javascript normally goes within the head.../head section, at which point the page headers were already sent, and doing a Location redirection within PHP will only result in an error. This can be done using PHP, the HTTP_USER_AGENT variable, the get_browser() function, and a browscap.ini file. Check out: http://www.php.net/manual/en/function.get-browser.php Make a script that determines the browser being used which redirects if necessary. Include this at the top of every page and voila!

Re: [PHP] MySQL
This is OT, I'm considering buying the MySQL, Second Edition Paul DuBois book. I'm using MySQL 3.23. Should I be buying the first edition DuBois book instead or does BuBois cover both 3 and 4 in the second edition? Is there a huge difference between 3 and 4? Here's a URL for the second edition: http://www.kitebird.com/mysql-book/ It discusses what's new in this edition. Paul DuBois is also very active on the MySQL mailing lists so your question would probably get a more detailed answer there. Also, in all likelihood, the first edition may not even be available anymore. Larry -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Yarrrrgggghhhhh || Simplest php question in existence........
Any performance issues re: using fetch_row vs. fetch_array? No significant performance issues. If you want to be precise and save a little overhead, use $row = mysql_fetch_array ($result, MYSQL_ASSOC); The returned record will ONLY be returned as an associative array.
