Build a tool that performs a static analysis of a group of files and make it easy for developers to use. This tool would generate the explicit declarations your codebase would utilize when answering such questions as "which classes implement interface foo". The file the static analysis tool generates could be easily hand editable, so developers could tweak it if they see issues (just in case the static analysis tool has bugs early on), or for small plugins, just quick crank out a couple lines by hand. As long as the static analysis tool builds a composite of class hierarchy established in all the files (project wide, at least in terms of the plugin), you wouldn't have to double declare interfaces so they could be detected.

[PHP] Class and interface location
Hi all. I'm trying to come up with a solution to an architectural problem I could use some extra eyes on. I have (or will have) a large code base with lots of classes, spread out over many optional plugin components. These classes, of course, will have interfaces on them. These classes will, of course, lazy-load using PHP's autoload capability. What I need to know is which classes implement which interfaces, so that I can load and use "all classes that implement interface Foo". There are a couple of approaches that I've considered, all of which I dislike for one reason or another. 1) Magic file naming. That is, any class that implements interface Foo lives in a $something.Foo.inc file, or some similar pattern. This has a number of problems. First, it means a huge number of file_exists() calls to determine if a given potential class exists, and then disk hits to load those files. While that information is possible to cache, it also means that we cannot have a class that implements two of the interfaces I'm interested in (a feature I will need) because then it would have to live in two files, which is clearly impossible. 2) Reflection. PHP makes it quite easy to get a list of all loaded classes, and to get a list of all interfaces that a loaded class implements. The catch there is "loaded". Reflection only works once you've loaded the code file into memory. Once you've done so, you cannot unload it. That means the code is sitting there in memory wasting space. Given the size of the code base in question, that could easily blow out the process memory limit. Even if we cache that information we derive from reflection we still have to load it the first time (or periodically when rebuilding the cache), which will blow the memory limit. The only alternative would be to have some sort of incremental rebuild across a multi-request batch process, the complexity of which makes my skin crawl. 3) Static analysis. Instead of reflection, either tokenize or string parse all files to determine what classes implement what interfaces and then cache that information. We are actually using this method now to locate classes, and it works surprisingly well. Because we never parse code into memory it does not ever spike the memory usage. However, it is impossible to determine if a class implements a given interface by static analysis unless it declare so itself with the implements keyword. If it does so indirectly via inheritance, either via the class or via the interface, it would not find it. That necessitates that any "detectable" classes must explicitly themselves declare their interfaces, even if it is redundant to do so. I don't like that approach, but it's the first one that strikes me as even viable. 4) Explicit declaration. In this approach we detect nothing and rely on the plugin developer to do everything. That is, they must provide somewhere (either in code or a configuration file) an index of all classes they offer, the interfaces they implement, and the file in which they live. While this makes the implementation easy, it is a huge burden on the plugin developer and I'm quite sure they'll forget to do so or get it wrong on a regular basis. 5) Wave a wand and let the magic ponies figure it out. I wish. :-) Can anyone suggest a better alternative? At the moment option 3 seems like the most viable approach, but I'm not wild about the implied performance impact nor the potentially redundant interface definitions it would require. --Larry Garfield -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

And finding a "library" or "toolkit" which does exactly what you want exactly the way you want may not be so easy. For example, I don't use MySQL unless I absolutely have to. But there aren't that many such systems based on PostgreSQL. I could take their MySQl code and hack it. But while analyzing their code, you find you could have done this yourself in half a day, less if you've done it before. I'm just thick enough to believe that most programming problems are relatively easily solved from scratch. And it's an interesting challenge to do so. Particularly when the result is something which can be reused in later projects. Yes, of course, I wouldn't touch payment gateways and the like. Paul -- Paul M.

Hi,
If it is a string "0", you should use: case "0".
Because in PHP, 0 == false == null. You need to know the difference between
== and ===.

Am 18.01.2011 01:33, schrieb Jimmy Stewpot:
Hello,
I currently have a strange issue where we are seeing 'random errors' being
displayed to end users. What I find most interesting is that in the php.ini
file we have the following error settings.
error_reporting = E_ALL& ~E_NOTICE
display_errors = Off
display_startup_errors = Off
log_errors = On
log_errors_max_len = 1024
ignore_repeated_errors = Off
track_errors = Off
I thought that if we had dislay_errors = Off then end users should never see
errors displayed on the web page. However at apparently random times we do
still see errors being reported, its not consistent at all. To give a better
idea of the problem we have 8 web servers, they all run an identical copy of
the site which is stored on a common netapp nfs filer. At apparently random
times we see that 1 out of 8 servers will reported strange errors like 'use of
undefined constant' or 'Undefined variable'. What's most strange about these
errors is that if the code was faulty wouldn't we expect to see the errors on
all web servers? and secondly wouldn't we expect to see the errors constantly
rather than at apparently random intervals?
The php.ini files have a modify time of mid 2010 and yet this problem has only
started in the last few weeks. Has anyone else experienced similar problems in
the past and if so what was the root cause?

Jimmy
Hi,
i think some developer has setting the display_errors with
ini_set('display_errors', true);
this is why your become the problems now. Maybe this is a idea?

Hi Daniel, good point (that I'm sure I would have caught ;-) ) about

Looks like it was the array indices syntax that was the culprit.
Also for others, yes, I'll be adding the var cleaning and checkers.
