# parse_ini_file

(PHP 4, PHP 5)

parse_ini_file -- Parse a configuration file

## 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`

> Megjegyzés: 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.

> Megjegyzés: If a value in the ini file contains any non-alphanumeric characters it needs to be enclosed in double-quotes (").

> Megjegyzés: Since PHP 4.2.1 this function is also affected by safe mode and open_basedir.

> Megjegyzés: As of PHP 5.0 this function also handles new lines in values.

> Megjegyzés: 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:

Példa 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"

Példa 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.
