Thanks so much everyone
files with the extension .php are read by a web server such as Apache,
which
has a php extension that process the php code in the .php file.
Php code IS NOT run by the client/browser software. The html or
combination
of html and javascript communicate with the server to process such
things as
form input. This confuses people often who are new to php because the
code
is written directly into the html file.
In a file with php code and a .php extension can process get queries
for instance it is possible to have an anchor tag in a web page with the
following value for the href attribute
<a href="somePhpCode.php?x=doSomething&y=showmewhatyoudid">contact the
server</a>
When this php code page is loaded from the server, the server code can
be written to look
for a $_GET variabls 'x' and 'y'
<?php
if($_GET['x'] && $_GET['y']) /* " if you see both (&& means and) of
these $_GET variables run the code in the braces */
{
// this is a comment. it is not processed: It only runs to the
end of the line
/*
this is also a comment. It can extend over multiple lines or be
very short and used
in the flow of the code to add information about the code.
*/
// Here you would expect $_GET['x'] = 'doSomething'; and $_GET['y']
= "showmewhatyoudid";
}
It then can produce some html markup and content that represents how
the server was coded
to process that input.
On the console, php can be written and run directly from the console or
from php code files, again with the extension .php.
There are texts available from publishers for beginning to advance
coding in php
There are also many tutorials on line, as well as forums and mailing
lists, such as
this.
If you are new to coding, you should get a good grounding on what
exactly coding
does and is used for.
If you have done programming in other languages, it should only be the
syntax and
features that you will need to become familiar with.
