 | Why reinvent the wheel and try to create a code style guide from scratch when there are plenty of sensical, logical and well documented style guides out there already that are accepted and in use in lots of projects? All you'll do with such a non-standard design is create a … |
| | PDFTK ([url]http://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/[/url]) could solve most if not all of your difficulty. The only caveat being its a command line utility so you have to interact with it in that fashion.

 | Re: OOP problem First, your class is mixing to many responsibilities. You should be passing an already established database into your quiz class if it is needed.

| | This is why ajax and php are ill suited for a real-time chat solution. Because it has to make a new request every n seconds which means you're hitting the system fresh every time since php does not really maintain state between requests. You would really want to look at … |

| | You would need two loops, one that would handle your conditional repetitions and one which handled the execution of your batch files. I would probably start with a [URL="http://php.net/manual/en/control-structures.for.php"]for[/URL] loop for the repetitions and a [URL="http://php.net/manual/en/control-structures.do.while.php"]do-while[/URL] loop for the batch statements. |
| | Your memory limit is set to 128MB not 13MB. In my experience with PHPExcel, you can expect between 1 - 10KB of memory usage on average per cell. Formulas and formatting causing even larger memory footprints. While it will require converting your workbook into 4 csv files, you will then …  |

 | I agree some further explanation is necessary. PHP is a server-side language so it is meant to run on a server. HTML5 introduces some client-side storage mechanisms, but their support is going to be relatively limited and I'd be hard pressed to use them unless you're targeting a specific platform … |
| | MySQL is not the same as MSSQL. You should not be using the mysql* functions to connect to a microsoft sql server.You want to be using the SQL Server driver ([url]http://msdn.microsoft.com/en-us/sqlserver/ff657782.aspx[/url])  |

It is simple to implement, very well documented and very well … |
| | Re: Best Encryption Hashing is not the same thing as encryption. Your examples are all hashing. If you need to be able to encrypt and decrypt the data than check out the php documentation for the mcrypt library. [url]http://php.net/manual/en/book.mcrypt.php[/url] |
 | hashing and encryption are two different things. hashes like MD5, SHA1, Whirlpool etc. are one way. There *should* NOT be a way to reverse them. Encryption however is two way. you can encrypt a string and when decrypted returns the same string. For hashes I agree with cwarn in the … |

| | vlowe, [edit] Err, I misread that initially [/edit] The PHP DateTime library would be my preferred method of doing what you want.

| | Be careful when using code like that with large files. That relies on your entire file being first read into memory. The better way to do this would be to iterate over the file line by line. [CODE] <?php $it = new LimitIterator( new SplFileObject( 'sometextfile.txt' ), 57 ); foreach( … |
| | I don't think I would put much stock in a product that "generated" source code for me, scaffolding like controllers is one thing, but not a whole project. @ardav I have to disagree with your comment about frameworks. Frameworks will save you from writing lots of code as they supply …  |
| | A quick look at the code you posted, and I see a few issues. 1. ) You are using php short tags. While this is not "wrong" it is not enabled by default in most php configurations and become a real headache if you're not looking for it. 2.) None … |
| | Re: hash_hmac To my understanding hmac variations are substantially less prone to collisions than the standard hash functions. I know this is not directly related to your question, but have you considered using bcrypt for your passwords?

| | Generally the templating functionality would be rolled into the "view" component of your MVC architecture, at least in some fashion. The code you have provided looks a lot more like a registry to me. However to better understand your design, I'd really like to see how you envision other classes … |
| | I'm not sure how your code is working in the first place. You can not echo out the value of a private or protected class member. So if your class does contain a private $no_of_items you can not display it directly. [CODE] <?php class bag{ private $no_of_items=0; private $sub_total; public …  |
 | Re: URL Help You are correct, this would need to be done with an .htaccess file. Essentially taking [url]www.example.com/####[/url] and mapping it to example.com/page.php?id=#### There are lots of examples and this has been covered quite a bit on these forums. |
 | Re: date_format () date_format() was throwing an error because the first parameter being supplied was not an instance of a [URL="http://www.php.net/manual/en/class.datetime.php"]PHP DateTime[/URL] object. It has nothing to do with what the database column is set as. If you're receiving a 1970-01-01 that means strtotime received a null value, or a value outside of … |

| | @newprimitive Please post your entire Connect class. It appears you're missing a large portion of it, even if you're getting an error on one of the lines you posted, the fact that you're calling $this->set_session() and $this->get_session() and those functions are not presented it is impossible to debug your code … |

 | Yes this is absolutely possible. The only library that is coming to mind is Zend_Mail [url]http://framework.zend.com/manual/en/zend.mail.read.html[/url] Other examples exists such as: [url]http://garrettstjohn.com/entry/reading-emails-with-php/[/url] Googling will yield a lot of different examples. |
 | For starters this is not a PHP issue, this is a javascript issue. On that note it appears you are using jQuery already. So you can add a couple listeners for the escape key press, any mouse click, and also if the search loses focus. [CODE] $(document).keypress(function(e) { if (e.which … |
| | If you're opening a mysql connection for every method call you are definitely doing it inefficiently. The best way to handle the connection would be to setup one connection per request, since php's scope is limited pretty much to each request, and pass it into all of your different objects … |

| | PHP is notoriously bad with UTF-8 characters. The only reasonable way I think you would accomplish this would be using the multi-byte functions.

| | Well for starters, your file is technically delimited by the space character. Since your rows are not identified with a unique id, I will assume that the user name is a unique field and thus could be used as your key. When you build you table, link the usernames to … |
