Xserverで変更できるphp.ini設定とは？

こんにちは、WPホームページ研究所の運営サポートチーム（@WP_LABO）です。

Xserverで変更可能なphp.ini設定をまとめておきます。php.iniはファイル１つあれば保存場所を確認できます。任意のファイル名（info.php等）で保存したphpに以下を記述して直接ブラウザで開くだけでOK。

<?php
phpinfo();
?>

以下の通り動作しているサーバー状況を確認可能です。

大元のphp.iniへのファイルパスが下記。

個別設定できるphp.iniファイルが存在する場合はドメイン配下に保存されています。

Xserverの場合はFTPからでも変更可能。

もちろん、サーバーのコントロールパネルからも変更可能。
