Arquivos .user.ini

O PHP tem suporte para arquivos de configuração INI por cada diretório. Esses arquivos são processados apenas pelo CGI/FastCGI SAPI. Essa funcionalidade torna obsoleta a extensão PECL htscanner. Se você estiver rodando o PHP como um módulo do Apache, use arquivos .htaccess para obter o mesmo efeito.

Além do arquivo php.ini principal, o PHP procura por arquivos INI em cada diretório, iniciando no diretório do arquivo PHP requisitado e continua o caminho até a raiz do documento atual (conforme definido na variável $_SERVER['DOCUMENT_ROOT']). Caso o arquivo PHP esteja fora da raiz do documento, apenas o seu diretório é procurado.

Somente configurações INI com os modos INI_PERDIR e INI_USER serão reconhecidos nos arquivos INI estilo .user.ini.

Duas novas diretivas INI, user_ini.filename e user_ini.cache_ttl controlam o uso de arquivos INI de usuário.

A diretiva user_ini.filename define o nome do arquivo que o PHP procura em cada diretório; se for definido como uma string vazia, o PHP não fará a varredura em tudo. O padrão é .user.ini.

A diretiva user_ini.cache_ttl controla a frequência de como os arquivos INI de usuário são relidos. O padrão é de 300 segundos (5 minutos).

"If you are using Apache, use .htaccess files for the same effect."

To clarify, this applies only to Apache module mode. If you put php directives in .htaccess on an Apache CGI/FastCGI server, this will bomb the server out with a 500 error. Thus, you unfortunately cannot create a config which caters for both types of hosting, at least not in any straightforward way.

Since the .user.ini is read from public directories, it's contents will be served to anyone requesting it and potientially show them sensitive configuration settings.

Add these lines to your .htaccess to block requests to it :
<Files ".user.ini">
Require all denied
</Files>

If you have no idea what "PHP_INI_PERDIR" or "PHP_INI_USER" are or how they relate to setting a .user.ini file, take a look at the ini.list page: http://www.php.net/manual/en/ini.list.php

Basically, anything in the "Changeable" column labeled as PHP_INI_SYSTEM can't be set in the .user.ini file (so quit trying). It can ONLY be set at the main php.ini level.

Trap for young players, not that I’m such a young player myself.

The default setting for user_ini.cache_ttl is 300 seconds, which means that it refreshes every 5 minutes. If you are tweaking the settings in .user.ini, it could take up to 5 minutes before you see the results of your experimentation.

If you don’t have access to php.ini where you can change this setting, you will have to learn to be very patient.

For those looking for an example... .user.ini should be formatted as a simple list of [KEY]=[VALUE]\n sets. For example, a one-line .user.ini file that serves solely to change the max allowable upload file size to 5Mb is:

upload_max_filesize="5M"

This article should be made clearer.
".htaccess-style INI files" meant to me that the ini settings had to follow the syntax used in .htaccess, but this is not the case!

You have to use
register_globals=on
and not
php_flag register_globals on

Also, the changes can take a while to propagate to all processes if you have a long process time out.
Restarting php-fpm can give you an answer quicker :)

Be aware that PECL htscanner doesn't work (yet) on PHP7.0.

'pecl install htscanner' throws an "zend_hash_update’ undeclared'" error.
