PHPのexceptionが増えてる！

知らない間にSPL(Standard PHP Library)とかいうものがPHPについてて

PHP5以降で利用できるらしい

うちのサーバはPHP5.2.0なんで使えるはずだから
昨日改造したこれ

var_dump(spl_classes());

で使えるライブラリを調べてみると

array(43) {

  ["AppendIterator"]=>  string(14) "AppendIterator"

おお！！
こんなにあったのね！

で、ここからexceptionの継承を見てみると

結構増えてる！

他にも結構使いそうなのがそろってるから大規模開発での使用とかいいかも

PHPも日々進化してるのね

俺もがんばろ・・・
