|
||
| 23 | * Ini file configuration engine.
|
||
| 24 | *
|
||
| 25 | * Since IniReader uses parse_ini_file underneath, you should be aware that this
|
||
| 26 | * class shares the same behavior, especially with regards to boolean and null values.
|
||
| 27 | *
|
||
| 28 | * In addition to the native `parse_ini_file` features, IniReader also allows you
|
||
| 29 | * to create nested array structures through usage of `.` delimited names. This allows
|
||
| 30 | * you to create nested arrays structures in an ini config file. For example:
|
||
| 31 | *
|
||
| 32 | * `db.password = secret` would turn into `array('db' => array('password' => 'secret'))`
|
||
| 33 | *
|
||
| 34 | * You can nest properties as deeply as needed using `.`'s. In addition to using `.` you
|
||
| 35 | * can use standard ini section notation to create nested structures:
|
||
| 36 | *
|
||
| 37 | * ```
|
||
| 38 | * [section]
|
||
| 39 | * key = value
|
||
| 40 | * ```
|
||
| 41 | *
|
||
| 42 | * Once loaded into Configure, the above would be accessed using:
|
||
| 43 | *
|
||
| 44 | * `Configure::read('section.key');
|
||
| 45 | *
|
||
| 46 | * You can combine `.` separated values with sections to create more deeply
|
||
| 47 | * nested structures.
|
||
| 48 | *
|
||
| 49 | * IniReader also manipulates how the special ini values of
|
||
| 50 | * 'yes', 'no', 'on', 'off', 'null' are handled. These values will be
|
||
| 51 | * converted to their boolean equivalents.
|
||
| 52 | *
|
||
| 53 | * @package Cake.Configure

||
