○ php.ini

・CentOS、HTML、PHP、MySQL共に言語はUTF-8に設定しています
・php-5.6.30で使っています、個人の設定に合わせて下さい
・オリジナルはソースに含まれるphp.ini-productionです
・完全コピーしないこと (エラーが出ることあり)
・";" で始まる行はコメントとして解釈されます
紫色文字 変更追加分 (defaultの部分も有る)

・disable_functions = phpinfoを設定するとphp情報が得られないので注意します
・"mbstring.script_encoding"は、"zend.script_encoding"で設定します
・"zend.script_encoding"を有効にするには、"zend.multibyte"をOnに設定します
・"date.timezone"を設定しないと、UTCタイムと判断されます
・iconv.input_encoding, iconv.output_encoding, iconv.internal_encoding および
・mbstring.http_input, mbstring.http_output, mbstring.internal_encoding は
・php-5.6.xでは非推奨です 代わりに default_charset を使いましょう

・opcache.soはデフォルトでextension_dirに入ります
・extension_dirを指定し、zend_extensionで指定します
