How to get phpinfo() variables from php programmatically?

Here you go:

1. ini_get_all() or get_loaded_extensions() were the closest I could find
2. php_uname()
3. apache_get_modules()
4. phpversion() was the closest I could find
5. stream_get_wrappers()
6. stream_get_transports()
7. stream_get_filters()

See also get_defined_constants() and some more.

As Chacha102 mentioned you can also use output control functions and parse the phpinfo():

ob_start();
phpinfo();
$variable = ob_get_contents();
ob_get_clean();

Due to the use of ob_get_clean() it won't mess up other output buffering levels you may be using.

Most of the stuff available from phpinfo() can be found in constants. Try looking through:

print_r(get_defined_constants());

Or the functions on this page: http://us.php.net/manual/en/ref.info.php. There are tons of functions to get information about specific extensions.

The following functions might be worth looking at:

ini_get() http://us.php.net/manual/en/function.ini-get.php
getenv() http://us.php.net/manual/en/function.getenv.php
get_cfg_var() http://us.php.net/manual/en/function.get-cfg-var.php
