Session Cache

If a user has missed something when they preview a form I want to return them with the back button or the cancel button to the previous page. Msie gives me the page expired error and firefox gives me a button to reload. But then of course all the entered information is gone... Pages are page1 (the form) page 2 (preview page) page 3 (confirmation page) I googled around and found this session_cache_limiter(private_no_expire); With that at the top of each page it works but then I realised that it might be a good thing to restict the length of time they can do this. I google

executing command with shell_exec()

Hi There, I execute a script in my php script with shell_exec(): $cmd = SCRIPT_PATH."PingGPSsource.py ".$_SESSION['prgIP']." ". $_SESSION['AVLIP']; logOutput("cmd:".$cmd); $avlRet=shell_exec($cmd); logOutput("result:".$avlRet); Now if i execute the $cmd in a normal shell, it works with no problem but when i execute it through my php script, $avlRet stays empty. Why is that and how can I fix this? Thanks for help and suggestions! Ron

Eregi possible problem

To fix another problem I turned errors reporting on (I normally have it off so users dont see errors that are not a problem). I then received a surprising message about another line of code that has worked for years. It says that eregi is depreciated, I am unsure what that means as my code was still working so its strange that this error came up as it is not an actual error. Maybe depreciated means we dont want you to use this any more but if you do its okay? Anyway I thought it best to change it just in case. I googled and found a link to a function called preg that looks like it

Php variables to an email.

I am collecting data and storing it in PHP variables. All it all its 33 variables. I store these in mysql after some controls and validation checks. I then want to send an email to the user to confirm the information and point out possible problems. I have tried but NONE of the variables are being read in and it just sends the raw php code with the variable names, Can someone point me in the right direction.... Thanks Garry Jones Sweden

A book I'd like PHP Training S such a book anyone?

get_object_vars ($this) and member visibility

Just a quickie. I've toying around with the SPL stuff to get an object to behave like an array. After looking at a few examples I noticed that they are using get_object_vars ($this) a lot. This all seems well and good when all an object's properties are public, but it hits a snag when you're using access protection (protected/private keyword), namely it exposes internal state that's supposed to be invisible to the outside world. Is there an alternative to get_object_vars ($this) that only exposes the public members?

Another heredoc question

as a quick aside. Is there a better place to ask php questions, since this ng is so overrun by spammers? I'm now looking at this example: <?php // testfile.php $fh = fopen("testfile.txt", 'w') or die("Failed to create file"); $text = <<<_END Line 1 Line 2 Line 3 _END; fwrite($fh, $text) or die("Could not write to file"); fclose($fh); echo "File 'testfile.txt' written successfully"; ?> Now I'm expecting, and the O'Reilly book is suggesting that the file should have 3 lines of text, since that is what the heredoc has. If I open the file with Notepad, it is just one line as

Class constructor in subclass

Again, I'm reading "Learning PHP, MySQL and Javascript" by Robin Nixon. In the section dealing with inheritance, he mentions that if a subclass is defined, the superclass constructor will not necessarily be run and one has to include special code in the constructor for the subclass to run the constructor in the superclass. He also mentions that the constructor could be either a method with the same name as the class (deprecated) or a method named __construct. Since it might not be obvious, how would one write a subclass and make sure to invoke the constructor without actually in

PHP strict standards?

I'm working through the O'Reilly book "PHP, MySQLm and JavaScript" by Robin Nixon and the following example is in the book. <?php Translate::lookup(); class Translate { const ENGLISH = 0; const SPANISH = 1; const FRENCH = 2; const GERMAN = 3; // ... function lookup() { echo self::SPANISH; } } ?> Now I'm supposed to get s simple "1" as output. Instead I get some warning about "Strict standards" (screenprint: http://i53.tinypic.com/28jkswl.jpg). Is it some new PHP thingie or is is something I can turn off in my PHP.ini or what? I looked through the

heredoc question

I'm trying to learn php and am reading a O'reilly book. They have an example of the heredoc function that, if I understand it, should preserve line breaks and carriage returns as follows: <?php $author = "Alfred E Newman"; echo <<<_END This is a Headline This is the first line. This is the second. - Written by $author. _END; ?> All I get is one continuous line of text in my browser. Even if I add \n at the ends of the lines, the browser displays only a single line of text like this: This is a Headline This is the first line. This is the second. - Written by Alfr

Unexpected behavior of int vs bool

I was very surprised to find the following while debugging. // Consider this simple function. function loop($n) { for ($i = 10; $i >= $n; $i--) echo "Loop $i\n"; } // I accidentally passed False (or NULL) to code like that. loop(False); This results in an infinite loop! This is not a bug. It is working exactly as documented. And I learned not to assume type conversions work as expected. Comments?

Software Best Practices Training topics required

Sorry to post this mundane question here, but I need help! I have to do a 1 hour Software Best Practices Training for some programmers in my company. Audience are Freshers to couple of years experience guys. Can you guys please suggest some relevant topics I can cover? I could think of the following: 1) Importance of following coding standards, indentation 2) Proper naming of files, variables, functions, classes, tables, columns, views and all other artifacts 3) Layer your application - each layer must address a specific concern 4) Abstract common stuff into reusable u

Sessions don't persist

Does anyone have any ideas why my php sessions won't persist on my server host. Everythink works perfectly locally on IIS/PHP laptop. When I upload to my ISP (also IIS/PHP/MySql platform, I cannot login to my own script because the session vars I set (on successful login) do not seem to persist across other pages. But here is the rub, the session vars that are set from values in the MySql database (on successful authentication) don't persist, but if I add a 'manual var', shown below as $_SESSION["TST"] , that does persist. I have checked all by inserting a 'print $row["ULX"]; etc

PDO Query Syntax

Suppose that I have a table SomeTable in my database with a column called SomeColumn and I wish to select the first line of this table. To do this in firebird I use: "Select First 1 SomeColumn From SomeTable" in Microsoft SQL Server I use "Select Top 1 SomeColumn From SomeTable" and in MySQL I use "Select SomeColumn From SomeTable Limit 1". Using ODBC I write only the query once and it translates the query to match the target database. Because of this I don't need to know which database I'm connected at the moment that I execute the query. Is PDO capable of doing the same thing? In

Is a virtual site-specific php.ini file possible?

I am helping someone migrate a blog site to a new hosting service that uses cPanel - WHS to provide the virtual sites. The blog software generates URL based includes which are disallowed by the current php instance. I know there is a directive to allow this but it needs to be for this specific site only. Is anyone aware of a method to achieve this? Any guidance appreciated. Thanks

GUI-based, installer-free HTTPd to run PHP scripts?

Hello I need a simple HTTP server with the following features: - available for Windows, preferably Win32-based instead of .Net-based so that any Windows user can run it - no installer required, so that I can stick the binaries in a ZIP file and users will simply have to double-click on the EXE to start the server - GUI-based application, not console-based - Once started, the application will/can be minimized to the icon bar so that it's unobtrusive - Supports calling the PHP interpreter, without having to specify the absolute path to the interpreter, so that I can stick

Hello all.

Tutorials on splitting strings

Can anyone point me to a tutorial that will help me undertake and understand the following. I have a string similar to that here "<p><img src="images/ imagename.jpg" border="0" alt="tags" title="title" align="right" / >Text Text Text Text etc etc." If the image name appears at the start of every string like this (but the name changes), how can I extract imagename.jpg from each string. Many thanks, Alec

Testing PHP Code

I'm organizing some functional testing for a PHP site, which will probably rely heavily on Perl's Test::WWW::Mechanize to simulate a browser environment. However, I'd like to have a series of Framework/ Library tests that perform basic input/output validation on class methods and library functions. Ideally, I'd like the output to mirror the Perl Test modules, but I'd be interested in any standardized testing mechanisms that have been developed for PHP. Thanks.

Processlist in PHP in consistent output format

Hello, I'm using Perl to store and interpret the output of the unix 'ps'- command. It works well on my machine (FreeBSD 6.2.), but it doesn't work on a few other unix variants that I tested. I came to the conclusion that the 'ps' output format is the culprit. This appears to differ across ps/top variants on several OS-es, even with the command line options mentioned in the docs. The script doesn't look for general system info, but detects the 20 most CPU-intensive processes ('ps -aux' or 'top -b' on FreeBSD), e.g.: PID USER THR PRI NICE SIZE RES STATE TIME WCPU COM

Das scheint eine grunds�tzliche Sache zu sein, ich sch�tze mein IIS ist flacsh konfiguriert, aber wo? (Win Vista) TIA, Haj�

multiply string with a comma
