The reason Facebook hasn't migrated away from PHP is because it has incumbent inertia (it's what's there) and Facebook's engineers have managed to work around many of its flaws through a combination of patches at all levels of the stack and excellent internal discipline via code convention and style - the worst attributes of the language are avoided and coding style is rigidly enforced through a fairly tight culture of code review (failing to adhere to the style and "going cowboy" by writing sloppy code results in pitiless mockery by one's peers).  Engineering management has never had to ...

I recently started working on a few Node.js applications. Coming most recently from PHP (and Drupal in particular), I found the transition to Node.js to be surprisingly easy. Pleasurable, in fact.

Node.js Is Built On Chrome's JavaScript EngineGoogle's browser, Chrome, has a notoriously fast JavaScript engine called V8. And this JavaScript engine can be cleanly separated from the web browser. Node.js is built on V8. This is one of the main reasons why ...

Did you know that inserting 2^16 = 65536 specially crafted values into a normal PHP array can take 30 seconds? Normally this would take only 0.01 seconds.This is the code to reproduce it:<?php echo '<pre>';$size = pow(2, 16); // 16 is just an example, could also be 15 or 17$startTime = microtime(true);$array = array();for ($key = 0, $maxKey = ($size - 1) * $size; $key <= $maxKey; $key += $size) { $array[$key] = 0;}$endTime = microtime(true);echo 'Inserting ', $size, ' evil elements took ', $endTime - $startTime, ' seconds', "\n";$startTime = microtime(true);$array = arra...

How can I execute PHP code on my existing myfile.html page?:When a web page is accessed, the server checks the extension to know how to handle the page. Generally speaking if it sees a .htm or .html file, it sends it right to the browser because it doesn't have anything to process on the server. If it sees a .php extension (or .shtml, or .asp, etc), it knows that it needs to execute the appropriate code before passing it along to the browser. Here is the problem: You find the perfect script, and you want to run it on your site, but you need to included PHP on your page for it to work. You ...

By default, PHP uses the 'PHPSESSID' cookie to propagate session data across multiple pages, and by default it uses the current top-level domain and subdomain in the cookie declaration.Example: www.domain.comThe downside to this is that the session data can't travel with you to other subdomains. So if you started a session on www.domain.com, the session data would become unavailable on forums.domain.com. The solution is to change the domain PHP uses when it sets the 'PHPSESSID' cookie.Assuming you have an init file that you include at the top of every PHP page, you can use the ini_set() functi...
