phpでのvar_dump()表示形式変更

注意：「 xdebug.so 」を読み込むと処理に時間がかかるようになるので、読み込むのは開発用/ステージングサーバーのみに絞った方が無難です。
時間的に約倍。下手すると倍超えまで時間がかかるようになります。

2023/07/04 AWS->OCIへのサーバー移行
※OCIサーバーでvar_dumpするとどのファイルの何行目かが分からないので。

今回のケースでは
```
[root@0206oci_webstaging php.d]# pwd
/etc/opt/remi/php56/php.d
[root@0206oci_webstaging php.d]# cat 20230704.ini
zend_extension=/usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/xdebug.so
[root@0206oci_webstaging php.d]# service httpd restart
Redirecting to /bin/systemctl restart httpd.service
[root@0206oci_webstaging php.d]#
/etc/opt/remi/php56/php.d/20230704.ini
```
👆このファイルを新たに作成する。

テキスト形式での表示からHTML形式での表示に変更
