Is Apache 2.0 Worth the Switch for PHP?
An anonymous reader writes "It seems like some of the members of the Apache Software Foundation are a little angry with the PHP Community because they don't recommend using Apache 2.0 with PHP. Since PHP is installed on half of all Apache servers this is a major issue for them. A number of high-profile PHP community members such as John Coggeshall and Chris Shiflett have blogged about this decision in light of a recent posting by Apache Software Foundation Member Rich Bowen which called PHP's anti-Apache2 stance FUD. Is there any real reason for the PHP community to start recommending Apache 2.0, especially when the 1.3.x series of Apache is rock solid and proven? Note Rich did later commend PHP for being a great product, so it's not all flames."
I should probably be noted that PHP used to be an official Apache Software Foundation project until it was mutually agreed to end this relationship. I have no clue as to what the underlying reasons were and as an ASF member myself would rather not speculate on this. See ASF Board Meeting Minutes for Feb 2004 (section 5.G).
P.S. Apache 2.0 is great and there is no reason not to use it IMO.
Apache 2 and a recent Linux kernel come pretty close to the theoretical limits of the hardware when it comes to serving static content. It just loafs along while saturating whatever net connection you give it. It's worth trying out.

I run a FreeBSD server with Apache 1.3.33 and PHP 4.3.10. When I was upgrading it a week or two ago to FreeBSD 5.3, I thought about making the switch to Apache 2.0. But then I thought ... What is that going to bring me?
Apache 1.3 has been working flawlessly for me. Until I have a compelling need to switch to Apache 2.0, I'm not going to. I understand that there are some nifty new features in Apache 2.0, but not a single one of them is something that I want/need.
This, I think, is the primary reason why people aren't going to Apache 2.0 in droves, not the PHP team's "FUD".
I'm using PHP on Apache 2.0 production servers right now. Honestly, I can say that PHP is more at fault for its own problems. I think that having lots of configurable options for a programming language is a bad idea. It leads to applications working on one installation of PHP, but not another. Administrators who enable things like safe_mode and turn off register_globals on shared servers are made fun of by ignorant programmers who don't understand what safe_mode is for and its usefulness. I have encountered all of this.
The one thing that I wish PHP would take advantage of in Apache 2.0 is the ability to run code as a user other than the web server. Every time I bring this up with the PHP developers, nobody really runs with it. A feature like this would make PHP much better in shared systems and prevent people from having to do weird things to ensure security. I guess PHP is not that great for shared systems right now.
The problem is running apache in WORKER or PERCHILD MPM modes. Those are the ones that are using threading.
What I'd recommend to anyone who wants to have a robust, fast apache implementation is to do the following:
There you go... performance increase for 75% of serving requests.
P.S: Avoid perchild at all costs!

Because v2 is more powerful. Filter chains for one. You can have the output routed through various modules and even shell commands before it's served up to the user. For example, if you want the output of a CGI to then go through server side includes expansion, then gzipped and served to the user. Apache 1.x doesn't have that kind of flexability.

As for putting a lock around them, I'd imagine that when that happens, it would be considered thread safe *except*...
PHP has a user contributed library system similar to CPAN called PEAR. Some of the libraries in PEAR aren't threadsafe... and even if somebody went through and updated them, next week there will be several new one that are not threadsafe.
Now, all of this would be moot if there were a compelling reason to push to Apache2. The impetus would be there to do the work. But, right now, the last of the 1.x series is just as stable and performs as well as Apache2. That means that there's simply no reason to do the work, and Open Source doesn't like to do unnecessary work.
When there is a benefit to the ongoing work necessary to make it and *keep* it threadsafe, it will likely be done.
