<h1>Preface</h1>
This document is part of the <a href="http://campcaster.campware.org/">LiveSupport</a>
project, Copyright &#169; 2004 <a href="http://www.mdlf.org/">Media

<h1>Scope</h1>
This document describes the PHP script file conventions for the LiveSupport
project. See also the generic description of the <a
href="fileConventions.html">file conventions</a> in the LiveSupport
project.<br>
<h1>Introduction</h1>
PHP scripts are text-based files containing PHP class definitions and/or commands.<br/>
They should adhere to the <a
href="http://pear.php.net/manual/en/standards.php">PEAR coding standards
conventions</a>.<br>
As text based files, they should adhere to the <a
href="fileConventions.html#textConventions">generic text-based
conventions</a>.<br>
<h1>Naming</h1>
A PHP script containing only class definition should have filename which reflects the class,
it is implementing.
Class names begin with a capital letter, followed by lower case letters.
In case of a multiple word file name, the first letter of each word is
capitalized.<br/>
Other PHP scripts should have name starting with lowecase letter.<br/>
PHP script files are named by the following rules:<br>
<ul>
<li>there are no spaces in the file name</li>
<li>for file names containing multiple words, each additional word
begins with a capital letter</li>
<li>the extension of the file is <code>.php</code><br>
</li>
</ul>
<h1>Structure</h1>
PHP scripts are partitioned by using the following 80 column wide partitioning comments:<br/>
<pre>
/* ==================================================== name of the partition */
</pre>
and
<pre>
/* ------------------------------------------------- name of the subpartition */
</pre>
The file has the following mandatory structure:<br>
<ul>
<li>PHP starting tag <code>&lt;?php </code></li>
<li>Header</li>
<li>Defines&nbsp;?</li>
<li>Include files&nbsp;?</li>
<li>Code sections&nbsp;+</li>
<li>PHP ending tag <code>?&gt; </code></li>
</ul>
Because PHP is in-HTML embedable script language, it is possible to mix PHP and HTML code
using PHP tags <code>&lt;?php</code> and <code>?&gt;</code>. This mixing approach is little bit
obsolete and it is better to use pure PHP (with structure described above) and some template system to generate HTML.
<h2>Header</h2>
The header holds all information mandated by the <a
href="fileConventions.html#header">generic guidelines</a>, but
are enclosed in the PHP multiline comments <code>/* */</code>. Note the 80
column wide partitioning delimiter enclosing the header.<br>

<h2>Defines<br>
</h2>
This section contains all the constant defines, similar as:<br/>
<br/>
<code>define('CONSTAT_NAME', 10);</code><br/>
<br/>
<h2>Include files<br>
</h2>
This section contains all the include files that the script needs
to include.
The include files are listed in
a most generic to most specific order: first PEAR classes, then
other LiveSupport module include files, and finally include files from
the same module / product are listed.<br>
Is much safer to use <code>include_once</code> or <code>require_once</code>, not the original versions
of this statement.<br/>
<br>
<h2>Code sections</h2>
This sections contain class definitions, function definitions or runable PHP commands.<br/>
<h1>Template</h1>
See a generic <a href="templates/phpScriptTemplate.phps">template
for PHP scripts</a>.
You may freely <a href="templates/phpScriptTemplate.php.txt">download</a> and copy this
template when starting to create a new script.<br>
