Is there a PHP Best Practices Book, Document, or web site that has
information similar to Perl Best Practices but for PHP?
Yeah, it's hard to find this stuff.
A google search on {+"Best Practices" +"PHP"} returned only
4,340,000 hits.
Maybe, some day, someone will think to write something up.
Good luck.

http://oreilly.com/php/index.html perhaps?
I dont know any free online best practice docs (other than the php.net
function comments) that sum it all up nicely.
But best practices are like coding standards; there are at least a few
that are (near-)equals.
Personally, the basis of my current coding style is as such:
- hungarianCasingConventionWithAbbreviationsWTFlikeSo
- almost always short names for variables in simple code < 40 lines
- almost always longer and descriptive names for more complicated code.
- usually short comments: explanations for noobs (to problem area)
- the rest of the "commenting" is done by the code using descriptive
var & function names
(last 3 points makes for "self-documented code")
- consolidate all logic in the script, so use specific sets
(_POST/_GET) rather than generic sets (_REQUEST)
- document it in script if behaviour is dependent on outside sources
(like php.ini)
- use of "config.php" in project rootdir to set DEFINE()s and any
global variables.
- use of adodb.sf.net for database abstraction.
- use a standarized directory structure for all php projects;
/project/.htaccess - RewriteRule -> php scripts
/project/php - all php scripts
/project/js - all javascript, including .js.php
/project/lib/component-x.y.z/ - all 3rd party libraries, regardless
of language, x.y.z=versionnum
/project/sql - sql init / maintenance scripts
(possibly) /project/theme/themeName/many.css(.php)
(or:) /project/css/some.css(.php)
(possibly:) /project/admin/
- use of an error handler that knows when to mail errors to developer,
when to print errs in browser and when not to, etc.
a "proper error handler". mine is still evolving.
- use of a standard debug output lib, called by a function that checks
config.php for a DEBUG_MODE define. prevents production machines from
showing debug info.
plug: my free http://mediabeez.ws/htmlMicroscope/ is kinda nice.
- push all input into DB through functions that prevent SQL insertion
(at least a filter through mysql_real_escape) and HTML/js/flash/etc
insertions (harder).
- an authentication scheme that can be called with simple functions,
but which also does checks on whether or not the IP that started the
session is the same as the IP making a request on a certain session.
- calling of the authentication scheme by nearly all scripts
- in any lenghty operation, design for continuation of the operation
when a given item fails.
example from OS file copiers: it stops when it needs to ask a
question. i rather design to "keep going", log all items that require
user interaction, and let the user deal with them when he/she has
time.
there's probably more that would make it into my best practices list,
but i'm gonna leave it at this for now..

Hello List.
I have some JS code that open a new window with a contact form in it.
When the link is clicked to open the new window, I will get the
following error SOMETIMES:
"Warning: Unknown: Your script possibly relies on a session side-
effect which existed until PHP 4.2.3. Please be advised that the
session extension does not consider global variables as a source of
data, unless register_globals is enabled. You can disable this
functionality and this warning by setting session.bug_compat_42 or
session.bug_compat_warn to off, respectively. in Unknown on line 0"
My JS code with a bit of PHP in it looks like this:
function loadOSS()
var oss_itemid = "<?php echo $item_id; ?>";
var loadOSS = window.open("my_url/my_file.php?iid=" + oss_itemid, "",
"scrollbars
=
no
,menubar
=
no
,height=600,width=600,resizable=yes,toolbar=no,location=no,status=no");
}
As I said above, the error message does not always appear.
Is the error due to the fact I am JS & PHP together?
Any help in understanding what I am doing wrong is appreciated.

i doubt you passed us the entire .js.php script..
does the script itself ever fail, asides from showing this msg?

I am talking about content caching, not opcode caching. If you have a
page with contents do change frequently, you can use content caching
(files, memcached, etc). Then PHP execution speed will be mostly
irrelevant because your script will be waiting most of the time for I/O
operations copying data from cache files or memcached server and the
user computer.

Hi,
I need an application to run mysql/php/apache or similar in one cd, to
make a presentation.
The presentation itself is a php site that uses mysql to do some
queries, to show data, and I would like to know how to embbed php and
mysql to one cd for a presentation. I mean; one cd containing the
whole site, and when the user inserts it on the cd/dvd reader it's
able to use the website like if him/her would be using the http
protocol. So, this application should let me put mysql/php/apache in
the cd, then it should work from the cd.
I would like to use some free software application, I would like to
avoid using commercial branches because I need this for a commercial
project that isn't able to pay licenses. Also I preffer Free Software.
So, if you know some appplication that helps me to develop this, and
also if I would be able to make the cd multiplatform for the principal
OS ( Gnu/linux, win, mac ) even better.
Thanks a lot.
Juan

If you want this sort of setup, then why not go with a live Linux CD/DVD
that has the website on. You can lock the live OS down so that it is in
what's called a kiosk mode, which should meet your requirements.

Hello All,
OSSCamp is again being organized in Chandigarh on April 10, 2010. This is
another step ahead to foster the open source community in the city
beautiful. At a Camp, we love to cross-talk, huddle together, raise some
noise, celebrate technology, argue over the coolest OS ever made, fight on
our fav programming languages, discuss stuff, and what not! PHP and other
open source web development technologies will be a major part of the
discussion at the camp. Would be great if you all join us at the the camp.
OSScamp Chandigarh April 2010

Something I came across which has been useful in removing the long
names (<php5.3 namespaces), is the use of class_alias().
My specific use is in DocBlocks for SOAP services. Using the Zend
AutoLoader, my classes are structured so that
Namespace_Package_Class_Exception is available in
\includes\Namespace\Package\Class\Exception.php
But having those long names in the SOAP WSDL file were a bit
cumbersome. So by having a class_alias in the important class files
(just after the class definition), I could use the alias names in the
docblock and all is well.

If you want server-unique session ids, use session_name() before
session_start()..?
session.entropy_file seems to be used only with /dev/urandom,
and seems to be used to _increase_ the differences betweeen
session ids.
