Description
array 
parse_ini_file ( string filename [, bool process_sections] )
     parse_ini_file() loads in the
     ini file specified in filename,
     and returns the settings in it in an associative array.
     By setting the last process_sections
     parameter to TRUE, you get a multidimensional array, with
     the section names and settings included. The default
     for process_sections is FALSE
    
Note: 
      This function has nothing to do with the
      php.ini file. It is already processed,
      the time you run your script. This function can be used to
      read in your own application's configuration files.
     
Note: 
      If a value in the ini file contains any non-alphanumeric
      characters it needs to be enclosed in double-quotes (").
     
Note: 
      As of PHP 5.0 this function also handles new lines in values.
     
Note: 
      There are reserved words which must not be used as keys for
      ini files.  These include: null, yes, no, true, and false.
      Values null, no and false results in "", yes and true results in "1".
      Characters {}|&~![()" must not be used anywhere in
      the key and have a special meaning in the value.
     
     The structure of the ini file is similar to that of
     the php.ini's.
    
     Constants may also be parsed
     in the ini file so if you define a constant as an ini value before
     running parse_ini_file(), it will be integrated into
     the results.  Only ini values are evaluated.  For example:  
    
     
| Example 1. Contents of sample.ini | ; This is a sample configuration file
; Comments start with ';', as in php.ini
[first_section]
one = 1
five = 5
animal = BIRD
[second_section]
path = "/usr/local/bin"
URL = "http://www.example.com/~username" | 
 | 
    
     
| Example 2. parse_ini_file() example | 
<?php
 define('BIRD', 'Dodo bird');
 
 // Parse without sections
 $ini_array = parse_ini_file("sample.ini");
 print_r($ini_array);
 
 // Parse with sections
 $ini_array = parse_ini_file("sample.ini", true);
 print_r($ini_array);
 
 ?>

       Would produce:
       | Array
(
    [one] => 1
    [five] => 5
    [animal] => Dodo bird
    [path] => /usr/local/bin
    [URL] => http://www.example.com/~username
)
Array
(
    [first_section] => Array
        (
            [one] => 1
            [five] => 5
            [animal] = Dodo bird
        )
    [second_section] => Array
        (
            [path] => /usr/local/bin
            [URL] => http://www.example.com/~username
        )
) |

     Keys and section names consisting from numbers are evaluated as PHP
     integers thus numbers
     starting by 0 are evaluated as octals and numbers starting by 0x are
     evaluated as hexadecimals.
