ini_get_all
The above example function called return_bytes() assumes that ini_get('upload_max_filesize') delivers only one letter at the end. As I've seen 'Mb' and things like that, I'd suggest to change the $last = ... part into $last = strtolower(substr($val,strlen($val/1),1)).
I'd call it $unit then.

Concerning the value retourned, it depends on how you set it.
I had the problem with horde-3 which test the safe_mode value.
THan :
- if you set the value with php_admin_value safe_mode Off (or On) ini_get returns the string
- if you set the value with php_admin_flag safe_mode Off (or On) ini_get returns the boolean.

Important: The manual says that ini_get will return 0 or an empty string for boolean config values that are set to off in php.ini.
This is technically correct, however when you use
php_value register_globals off
in an .htaccess file, ini_get will return the string, which will "evaluate" to 1. So if you are using mod_php you have to check boolean config values against the strings (upper/lowercase etc.) anyhow or you will get wrong results.

You can set custom entries in the ini file to provide globals such as database details.
However these must be retrieved with get_cfg_var, ini_get won't work.

It might be useful for included scripts that include other files to extend the 'include_path' variable:
<?php ini_set('include_path',ini_get('include_path').':../includes:'); ?>
Sometimes, it may also be useful to store the current 'include_path' in a variable, overwrite it, include, and then restore the old 'include_path'.

If you want to test ini flags (eg. On/Off), I recommend to explicitly cast the value returned by ini_get() to boolean - it is cleaner as you only get true or false, not 0 or 1 or "" as described above.
<?php
$register_globals = (bool) ini_get('register_gobals');
?>
C fans may of course also cast it to (int) to play with 0 and 1 - that's also cleaner to print().
