Otherwise, you have to follow the given procedure to install PHP on your computer. If your PHP or Apache versions are different then please take care accordingly.

Step 1 If you have not already done so, unzip and untar your Apache source distribution. You will keep all your PHP files in this directory. Every time you change your HTTP configuration or php. The actual PHP files in the directory need only be world-readable Save this file in your Web server's document root as info. Start any Web browser and browse the file. This is likely to be quite an old build, and it probably lacks many of the less common extensions. All you need to do is edit your Apache configuration file and turn on the Web server.

Restart the Web server. You will see a long table of information about your new PHP installation message Congratulations! If your PHP version is different, then please take care accordingly. Copy some. You need php5ts. It is possible you will also need other files from the dlls subfolder, but start with the two files mentioned above and add more if you need them.

Copy either the php. Open this file in a text editor for example, Notepad. Edit this file to get the configuration directives. Make sure this matches the IIS Inetpub folder or wherever you plan to serve out of. Stop and restart the WWW service. Select it and click Stop. Stopping and restarting the service from within the Internet Service Manager will not suffice. Since this is Windows, you may also wish to reboot.

Open a text editor. If your PHP and Apache versions are different then please take care accordingly. The installer will also ask you whether you want to run Apache as a service or from the command line or DOS prompt. We recommend you do not install as a service, as this may cause problems with startup. Search for the word DocumentRoot which should appear twice and change both the paths to the directory you want to serve files out of.

Older versions of Apache split up httpd. Apache server has a very powerful, but slightly complex, configuration system of its own. If you have standard installation then httpd.

In safe mode, this value will be ignored; instead, you must use the timeout value in php. You can choose any directory as the document root. Remember that you can associate any file extension with PHP like. The php. In other words, httpd is restarted for the module version or with each script execution for the CGI version. If your change is not showing up, remember to stop and restart httpd.

If this directive is empty, most variables are alterable. Previously, this necessitated hand- editing the C code from which PHP was made. Filesystem, system, and network functions should probably be the first to go because allowing the capability to write files and alter the system over HTTP is never such a safe idea.

Therefore, this is the main way to make a script time-out in safe mode. In Windows, you have to abort based on maximum memory consumed rather than the time.

You can also use the Apache timeout setting to timeout but that will apply to non-PHP files on the site too. The development servers should be set to at least the default; only the production servers should consider a lesser value.

You can change this order around. The variables will be overwritten successively in the left-to-right order, with the rightmost one winning the hand every time. In real life, this does not happen much.

This is now deprecated, and as of PHP4. Use the superglobal arrays instead. All the major code listings in this book use superglobal arrays.

Remember that SQL adds slashes to single quotes and apostrophes when storing the strings and does not strip them off when returning them.
