Each week you will need:
Week by week you will have to perform a number of activities in class. To be able to engage effectively you must be familiar with your textbook and I do strongly suggest that you take your textbook in class every time.
If you get stuck at any point during this week's activity, please follow the documentation in your textbook. The documentation in the book is euxastive and covers Linux, Windows and Mac architectures.
The book will go through the installation of Apache 1.x; I do recommend that you install version 2.2 or 2.4 instead. Most of the steps in the installation are identical.
Your first step is to install the software that we are going to need to use PHP effectively - in this order:
This documentation will cover installing the software stack on Windows only. You can also use WAMP distributions instead - as XAMPP or WampServer and we will look at it later on in the second half of this module.
They are suitable as a development environment - but for production you should install the individual packages (ideally, on Linux or on another Unix-like system).
Before we start, keep in mind that you need to be able to install software in the system (be a "local administrator" or "elevated user" in Windows) to be able to proceed with the installation of Apache and PHP.
If you do not have the appropriate rights, you cannot proceed with the installation of Apache and PHP.
If you are in our lab, we will be doing this within a virtual machine.
Download and install the latest stable version of Apache HTTPD available on the Apache Lounge web site. You should be able to follow the links and find the right version (64 bits vs 32 bits, depending on your operating system).
PHP is compiled using VC11, so we will need to use the VC11 version of Apache (as of 08/09/2015).
You can use the default settings - the task shouldn't take over 15 minutes.
Apache will be installed under your
Programme Files or
Programme Files (x86) folders.
After you have installed the web server, try to open your defaul home page at http://localhost/.
Please refer to Installing Apache Under Windows in your core text book if you run into troubles in the installation.
The main web server configuration is located in
conf/httpd.conf (we will need to modify this when installing PHP).
The log files (
error_log) are located in the
error_log file and verify if any errors have been logged, and why.
You can stop the server to free resources and you must restart the server after any changes in the configuration. To start/stop/restart the server, you can use the Services administration tool or the command line (
net start|stop apachexyz).
The Apache installation also installs a set of menu items to start/stop/restart the server.
For more details, follow the Microsoft documentation.
To use a recent version of PHP (PHP > 5.3), you will need a version of Apache compiled with Visual Studio 2012 - VC11.
Please refer to the Apache documentation.
Download and install PHP the from the PHP web site. Download the thread safe version, and follow this documentation: https://www.php.net/manual/en/install.windows.apache2.php
The version of VC used to compile PHP must match the one used for Apache (look for the string VC9, VC10 or VC11 in the PHP links). If you have installed an Apache compiled with VC11, you need to have a version of PHP compiled with VC11.
Install PHP as an "Apache handler" and make sure that you change your
httpd.conf file as per documentation.
Make sure that the DLL that you are loading matches both the version of Apache that you are using (e.g. 2.2) and the type of installation ("Apache handler"). For Apache 2.4 and PHP5, the files is
php5apache2_4.dll. For Apache 2.2 and PHP5, the file is
Installing PHP on Windows can be troublesome and can take anything between 10 minutes and several hours.
The main PHP configuration is located in
php.ini. You will not need to modify the file now, but you may need to modify it for advanced usage of PHP, in the second part of this course.
You can run PHP scripts:
You can use PHP both to write command line scripts and web pages/applications.
You should test and debug command line scripts in the proper environment; occasionally it might be convenient to debug web pages from the command line (e.g. to increase the level of verbosity without changing PHP settings).
Create a text file in your Apache root folder (
htdocs) with your notepad and call it
Include this code:
<?php phpinfo(); ?>
Restart Apache and open http://localhost/test.php.
You can run PHP scripts from the command line.
Open a command prompt and change to your Apache
c:\Program Files\php\php.exe test.php
Update paths as needed to reflect the local folder structure.
Remember: we are going to use Open Source software only; Apache and PHP are available for Windows, Mac and Linux.
You can download and use the software at home.
If you use a Mac, you can use this guide as a starting point.
If you are using RHEL, Fedora or Centos Linux, just run:
yum install httpd php
If you are using Debian or Ubuntu Linux, just run:
sudo apt-get install lamp-server
Seek help! You need to complete all the previous steps before moving forward.
If, for any reason, the Apache + PHP combination doesn't work, you can still test you PHP page using the built-in web server included in PHP since version 5.4.
test.php file in the PHP folder.
Open a terminal in the PHP folder and run:
php.exe -S localhost:8000
Then open your browser at the address http://localhost:8000/test.php
