需要は無いかもしれないが、ini形式をyaml形式に変換する処理を書いてみた。 ref: http://qiita.com/items/12cc1bf4b6e1c4ec5703

<?php
$ini = parse_ini_file($_SERVER['argv'][1],true);
foreach($ini as $section => $conf){
    echo $section,":\n";

    //sction内ループ
    foreach($conf as $key => $val){
        if(is_array($val)){
            echo " ",$key,":\n";
            foreach($val as $num => $file){
                echo "  - ",$file,"\n";
            }
        }
        else {
            echo " ",$key,": ",$val,"\n";
        }
    }
}
?>
