Automatic ixed loading

Most operating systems and installations of PHP will load the Protected scripts without any modification. PHP will be able to find and load the appropriate loader if the following conditions are met:


1) Operating system and PHP mode:

Linux or FreeBSD - PHP installed as CGI or CLI
Linux or FreeBSD - PHP installed as Apache module (with thread safety off)
Windows - PHP installed as CGI or CLI


2) Thread Safety is disabled. You may check phpinfo() output for this.


3) dl() is enabled. You should have enable_dl=On in your php.ini.


4) The PHP extensions directory needs to exist. Please check that the extension_dir= option in php.ini points to the real directory. Some hosting companies have incorrect installations of PHP and this can cause problems.


5) The latest ixed loaders are installed in an /ixed/ subdirectory within your scripts directory or any parent directory. Examples are below:

Example 1:
(loaders are in the /ixed/ subdirectory within the scripts directory)

/home/mysite/www/myscript1.php - your protected script(s)
/home/mysite/www/myscript2.php - your protected script(s)
/home/mysite/www/subdir/otherscript1.php - other protected script(s)
/home/mysite/www/subdir/otherscript2.php - other protected script(s)
/home/mysite/www/ixed/ixed.* - script loaders

Example 2:
(loaders are in the /ixed/ subdirectory within any *parent* directory)

/home/mysite/www/myscript1.php - your protected script(s)
/home/mysite/www/myscript2.php - your protected script(s)
/home/mysite/www/subdir/otherscript1.php - other protected script(s)
/home/mysite/www/subdir/otherscript2.php - other protected script(s)
/home/ixed/ixed.* - script loaders


6) (For windows users only) extension_dir= option in php.ini should point to the directory located *on the same drive* with your document root and scripts directory.



Manual ixed installation
It is possible to Manually install the ixed and this is required in the following conditions:


1) Operating system and PHP mode:

Linux or FreeBSD - PHP installed as Apache module (with thread safety on)

Windows - PHP installed as Apache module (thread safety is always on)


2) If Thread Safety is enabled. You may check phpinfo() output for this. PHP installed as Apache module under Windows will always have Thread Safety on.


3) If dl() is disabled. You have to enable_dl=Off in your php.ini.


Manual installation may be used even if automatic loading is available. With appropriate and manually installed loaders you give the maximum performance for your protected scripts. This is because the script will not need to search for a loader each time it runs.


For manual installation of protected script loaders you should have access to the php.ini configuration file. Manual installation is easy:


1) Check phpinfo() output for PHP version, Thread Safety mode and extension_dir path.

2) Copy the latest loaders into the /ixed/ subdirectory of your PHP extension_dir

3) Add one line into your php.ini with the appropriate loader name. This will depend on your OS, PHP version, and Thread Safety mode. Please refer to the Loader filename structure section above.
