Detailed Description

INIFile Parser.

Early access in init proceess! Avoid further dependencies like logging or other services

Description:

A Simpe Ini File Implementation to keep settings in a simple file instead of in a DB Based upon class.INIfile.php by Mircho Mirev mirch.nosp@m.o@ma.nosp@m.cropo.nosp@m.int..nosp@m.com

Usage Examples: $ini = new IniFile("./ini.ini"); Read entire group in an associative array $grp = $ini->read_group("MAIN"); //prints the variables in the group if ($grp) for(reset($grp); $key=key($grp); next($grp)) { echo "GROUP ".$key."=".$grp[$key]."<br>"; } //set a variable to a value $ini->setVariable("NEW","USER","JOHN"); //Save the file $ini->save_data();
