Installing PHP5 on Windows
The installation of PHP5 on windows is a manual
process and is a little bit simpler than one on Linux. It has four
basic phases:
-
Create the target directory, D:\PHP.
-
Unpack the distribution into the target
directory.
-
Fix the parameter files of both Apache and PHP.
-
Configure add-ons like Oracle OCI8 module and
PEAR.
The first two steps are trivial and can be
accomplished by using the Internet Explorer and WinZip or equivalent
utilities. Here is what the d:\PHP directory should look like after
unpacking the distribution from the PHP web site (http://www.php.net).
The next phase to
complete is adjusting the Apache configuration files and making sure
that the Apache server is aware of the PHP installation. The Apache
configuration file is called httpd.conf and resides under the Apache2
directory.
The Apache web server
must be restarted for the changes to take effect. The changes to the
httpd.conf are almost identical to the changes done in Linux; the user
needs to load the PHP5 module and tell the server what to do with the
files with the extension .PHP. In addition, the web server needs to
know that in the PHP directory all backslashes (“\”) are to be
converted into forward slashes. These modifications are marked with
gray color:
Add a test directory by
adding the following into the httpd.conf:
Now, restart the web server. There are several
ways to do this. The simplest way is to restart it as a service, from
the standard control panel menu. To do so, invoke the
Settings->Control Panel->Administrative Tools->Services menu. If
everything is done correctly, the resulting menu should look like
this:
Services are ordered alphabetically, and Apache2
should be among the first few. Right-clicking on the Apache2 service
will bring up another menu with “Restart” as one of the options.
Choosing this option will restart Apache2. Now, the “first.php” file
containing the call to the phpinfo()
function can be created and placed in the
d:\testweb.
The file looks like this:
<?php
phpinfo();
?>
If everything is correct and
http://localhost/work/first.php is entered as the URL into
Internet Explorer, a picture like the one below should appear:
This process is almost complete. Yet, the OCI8
module is missing. If the user scrolls down the first PHP page, OCI8
will not be there. In order to make it available to the PHP, d:\PHP\php.ini
needs created and edited. As with the Linux installation, it is copied
from the php.ini-dist file. The commands are entered from the DOS
window:
C:\>d:
D:\>cd PHP
D:\PHP>copy php.ini-dist php.ini
1 file(s) copied.
D:\PHP>
Now, php.ini can be edited by the notepad or a
favorite text editor. Locate the following line and remove the
starting semicolon:
;extension=php_oci8.dll
The resulting line should read:
extension=php_oci8.dll
When this is done, locate the line that tells PHP where to look
for extensions and modify it to contain the full path of the directory
with the PHP-extensions. In the case of this installation, the line in
question should look like the following:
extension_dir
= "D:\PHP\ext”
Do not replace the backslash characters with the
forward slashes in php.ini, as was done in httpd.conf. To complete the
PHP5 installation with the OCI8 module, restart the Apache web server.
If it is successful, the user should try executing their first PHP
script once again. The next picture shows the desired result:
All that is left to
complete the installation is to install PEAR and ADOdb.
