Is greater comfort with Windows a good enough reason to switch from PHP to ASP.NET?
Learning Linux really isn’t that hard, and it will dramatically increase your potential horizons as a programmer. Install Ubuntu on a virtual machine on your laptop and start running through some tutorials.
[... 53 words]How log in my e-mail and send sms via php?
If you want to send SMS via PHP I suggest taking a look at www.twilio.com—they are pretty inexpensive and ridiculously easy to get started with.
[... 44 words]What is the best framework to use, Yii or Ruby on Rails?
This is a big decision, and it’s worth taking the time to pick what’s the best fit for you. I recommend going through the tutorials for each one, building the basic application they describe and seeing which made the most sense to you. As a Django developer, I suggest trying that framework too :)
[... 126 words]How can I get access to the PHP script of websites like Dropbox?
If a website doesn’t deliberately publish its server-side code (some sites like reddit do this, but it’s pretty rare) then you won’t be able to see it. You can search for an open source clone but these will often be pretty low quality—the smartest open source developers tend to work on libraries that solve common problems rather than putting their efforts in to building complete clones of existing sites.
[... 175 words]Does creating a zip file with php use more RAM then CPU? Or vise versa? Also, is it faster to use a system call, or the php zip library? Exec (zip filename.zip) vs. $zip =new ZipArchive().
You can find out the answer yourself using a very simple benchmark—just call time() before and after each option and loop them a few thousand times to calculate an average.
[... 74 words]Which should I learn: Python or PHP?
Python will teach you more about programming than PHP—and you’ll be able to learn PHP easily if you learn Python first.
[... 36 words]System Administration: What service/product do you recommend for central logging of events and errors from multiple servers? Why?
We rolled our own solution to this using MongoDB, due to its super-fast writes and ability to store, index and search JSON. We were also attracted by its capped collections, which make it easy to e.g. only log the last 100,000 items.
[... 113 words]How can you build a search engine for a website built in PHP/MySQL?
There are a bunch of options.
[... 310 words]What are XML feed best practices?
It sounds like you’re pretty much screwed already, if you’re dealing with companies that still think FTPing XML around is a sensible thing to do.
[... 364 words]Is there a framework that allows me to collect input from individual users, and then charge for the aggregate and analysis of that data?
No—your needs are extremely specific. You’re going to have to build this yourself.
[... 95 words]What are some good examples of a first PHP app to build for someone who is learning?
Build a blog. Blog engines are, in my opinion, the ideal starter project for learning any server-side web technology.
[... 172 words]Can someone improve their knowledge of programming in Ruby or PHP by using a framework like Rails or Zend, or does the framework just do a lot of the work for you without giving you an opportunity to learn from it?
Read the source, luke.
[... 82 words]How are real time web applications achievable with PHP?
You don’t need to build your comet server using the same technology as the rest of your site.
[... 181 words]What are the tradeoffs (e.g. development speed, performance, scalability) between using various php frameworks, ruby/rails, or python/django? Is there any reason to choose one overwhelmingly over another?
At this point, I’d argue that the decision between them comes down to programming language rather than framework—the frameworks have mostly converged on a very similar set of features.
[... 145 words]In what circumstances should one use “magic quotes” in PHP?
Absolutely never. Magic quotes was a badly designed feature, and PHP has been trying to escape its legacy for years. If you are constructing SQL strings using string concatenation you’re asking for trouble—use prepared statements or a library that interpolates and correctly escapes variables for you.
[... 65 words]djng—a Django powered microframework
djng is nearly two weeks old now, so it’s about time I wrote a bit about the project.
[... 1501 words]Getting from point A to B (the right way)
If your laptop is relatively recent it might have hardware support for virtualization (Intel Core Duo chips do, for example). If so, it’s worth looking in to using VMWare or Parallels to run a virtual linux server locally on your machine. You’ll need a fair amount of RAM for this as well—2 GB minimum probably.
[... 194 words]Testing a new version of IXR
Almost two years to the day since the last release, I’ve put together a new version of IXR, my PHP XML-RPC library. I haven’t published it on the site just yet as I want to make sure any bugs are ironed out first, but you can grab a copy here:
[... 177 words]Zend PHP 5 Goodies
Zend have quietly released a veritable treasure trove of PHP 5 tutorials via their PHP5 InfoCenter:
[... 212 words]PHP 5 Release Candidate 1
I haven’t blogged much about PHP in a while because I’ve been up to my nose in mod_python and loving every minute of it. This news is just too important to miss: PHP 5 Release Candidate 1 has been released, bringing the first production-ready release tantilisingly close. While I doubt PHP 5 will tempt me back it’s definitely an exciting upgrade—my biggest complaint with PHP 4 is the brain-dead object model which defaults to copying whole objects rather than passing references, and this is one of the many things addressed by PHP 5. The new libxml2 powered XML features sound really powerful, and SQLite as an on-board database should be ideal for knocking out small stand-alone applications without needing to set up a mySQL database for them.
[... 173 words]An apology
It turns out that the Javascript on PHP.net mentioned previously was not deliberately obfuscated to protect the code from prying eyes; it was merely compressed to reduce the size of the script. See this comment for further details. I’d like to apologise to the maintainers of PHP.net for jumping the gun on this issue. Incidentally, the unobfuscated code is now available in CVS.
[... 72 words]The good and the ugly
PHP.net has a new feature on their search page—a really nice implementation of an auto complete text widget in Javascript. Even better, the search page is valid XHTML 1.0 Strict and uses CSS for the layout. Let’s hope this is an indication of things to the come for the rest of the site, which still mostly consists of tag soup.
[... 368 words]PHP Library Tips
Kellan Elliott-McCrea (author of the popular Magpie RSS parser): A Few Tips for Writing Useful Libraries in PHP. Kellan makes the interesting observation that PHP encourages a culture in which most development occurs in the context of either full applications or C extensions, with few people devoting themselves to releasing libraries.
[... 56 words]PHP philosophy, and bundling SQLite
Here’s a great quote from Rasmus Lerdorf (the creator of PHP) for people who have become disheartened with PHP’s lack of elegance when compared to other languages such as Python:
[... 232 words]Supporting Conditional GET in PHP
This site’s RSS feeds now support Conditional GET. Since the feeds are dynamically generated on every request, adding support took a bit of hacking around with PHP. Here’s the function I came up with (based on the excellent description provided by Charles Miller in the article linked above):
[... 398 words]Verbose Regular Expressions
Ned Batchelder describes Verbose Python regular expressions. This is one of the things I’ve known about (as in known that they exist) for ages but have never got around to using. I’ve been working with some pretty heavy regular expressions recently that could really do with the clarity of being defined in verbose format with comments.
[... 96 words]Hashing client-side data
Via Scott, a clever PHP technique for ensuring data sent to the browser as a cookie or hidden form variable isn’t tampered with by the user:
[... 248 words]Girlfriend as a case study
I’ve been helping my girlfriend recreate her site using CSS and structural markup. She’s new to web design and has been taking to CSS like a duck to water—as a veteran of Microsoft Word globally defined styles come to her naturally and she took very little time to cotton on to the importance of seperating presentation from content. I’ve shown her tables as well but she isn’t really interested as she sees CSS as a much better solution for general presentation. I’m hoping to help run an HTML/XHTML/CSS training course at the University early next year with a heavy emphasis on structural markup, standards compliance and accessibility so it’s great to have a guinea pig to play with :)
[... 201 words]PHP generated PDFs
R&OS PDF PHP classes (via tidak ada). This is the most useful PHP library I’ve seen in a long time. It allows dynamic generation of PDF files without needing any additional modules installed on the server (although GD is required if you want to add images to your PDFs). It is extremely easy to use and has an impressive set of features, including PDF drawing tools, built in page number support and excellent documentation. On the topic of PDFs, Yes You Can advocates their use for presentations and touches on a method of generating them using Python.
[... 113 words]Magic quotes solution
Pink Goblin (otherwise known as HarryF) explains why magic quotes are evil. This is an issue that every PHP developer should be aware of, as it can cause all kinds of problems in your scripts if you ignore it. He suggests using a custom myAddSlashes() function which only calls addslashes() if magic quotes are turned off. I have an alternative solution—chose your preferred setting (quotes on or off) and apply it at run time to all incoming data in one go. My code for doing this is available here. By a bizzare coincidence I wrote the script this morning, then spotted a link to the Pink Goblin article on tidak ada literally five minutes after finishing it.
