user_login/.htaccessでInvalid command 'php_value'～が起きていることを確認。

#user_login/.htaccess

(修正前)
php_value output_buffering ON
php_value default_charset UTF-8
php_value mbstring.detect_order SJIS,EUC-JP,JIS,UTF-8,ASCII
php_value mbstring.http_input pass
php_value mbstring.http_output pass
php_value mbstring.internal_encoding UTF-8
php_value mbstring.substitute_character none 
php_value mbstring.encoding_translation OFF
⇓
(修正後)
SetEnv php_value output_buffering ON^Mdefault_charset UTF-8^Mmbstring.detect_order SJIS,EUC-JP,JIS,UTF-8,ASCII^Mmbstring.http_input pass^Mmbstring.http_output pass^Mmbstring.internal_encoding UTF-8^Mmbstring.substitute_character none^Mmbstring.encoding_translation OFF

下記サイトを参考にuser_login/.htaccessを修正したが、結果は変わらず。

heroku上でphpがどういう動作モードで実行されているかを把握していますか？ それによってパラメータの与え方もできることできないことが変わってくるので大事なことです。

Answer 1

HerokuでPHPを使うときに気を付けるところという記事を読むと、
.user.iniで与えた方が確実そうです。

ご回答ありがとうございます。
.user.iniを追加したところ、正常に動作しました。

■.user.ini
[PHP]
upload_max_filesize = "10M"

[Date]
date.timezone = "Asia/Tokyo"

[mbstring]
mbstring.language = Japanese
mbstring.internal_encoding = UTF-8
mbstring.encoding_translation = Off
mbstring.func_overload = 0
