$ini and $readini functions for PHP

Usage:
ini("file",N)
Returns the name/Nth position of the specified topic/item in an ini/text file.
The item/N parameter is optional. If you specify N = 0, it returns the total number of topics/items.

readini("file","section","item")
Returns a single line of text from an ini file

Example:
test.ini

[FirstRow]
steamid=Yak

[SecondRow]
steamid=Yik

[ThirdRow]
steamid=Yadjd

[FourthRow]
steamid=cols

    function echor($text=NULL) {
        echo $text."<br />";
    }
    $file="test.ini";
    echor("Sections in file: ".ini($file,0));
    echor("");
    for ($i=1;$i<=ini($file,0);$i++) {
        echor("Section ($i): ".ini($file,$i));
    }
    echor();
    for ($i=1;$i<=ini($file,0);$i++) {
        echor("Section ($i): ".ini($file,$i));
        echor("-Options: ".ini($file,ini($file,$i),0));
        for ($z=1;$z<=ini($file,ini($file,$i),0);$z++) {
            echor("--Option ($z): ".ini($file,ini($file,$i),$z)." Value ($z): ".readini($file,ini($file,$i),ini($file,ini($file,$i),$z)));
        }
        echor();
    }
