PHP Class Config_Lite

read and save ini text files. Config_Lite has the native PHP function `parse_ini_file' under the hood. The API is inspired by Python's ConfigParser. A "Config_Lite" file consists of "name = value" entries and sections, "[section]" followed by "name = value" entries

Method Details

__construct() public method

the save' and read' methods relies on a setted filename, but you can also use `setFilename' to set the filename.
public __construct ( string $filename = null, integer $flags = null, integer $mode )
$filename string - "INI Style" Text Config File
$flags integer - flags for file_put_contents, eg. FILE_APPEND
$mode integer - set scannermode

__toString() public method

since a empty config is valid, it would return a empty string in that case.
public __toString ( ) : string
return string

buildOutputString() protected method

Generated the output of the ini file, suitable for echo'ing or writing back to the ini file.
protected buildOutputString ( array $sectionsarray ) : string

get() public method

to get an option by section, call get with a section and the option. To get a global option call get' with null as section. Just call get' without any parameters to get all sections and options. The third parameter is an optional default value to return, if the option is not set, this is practical when dealing with editable files, to keep an application stable with default settings.

$sec string Section|null - null to get global option
