A partir de PHP 5.3.0 se incluye soporte para ficheros de configuración INI a nivel de directorios. Estos ficheros solo los procesa la SAPI CGI/FastCGI. Esta funcionalidad deja obsoleta la extensión PECL htscanner. Si está usando Apache, use los ficheros .htaccess para lograr el mismo efecto.
Además del fichero php.ini principal, PHP explora cada directorio en busca de ficheros INI, empezando por el directorio del fichero PHP solicitado, y continuando hasta el directorio raíz de documentos (tal y como esté establecido en $_SERVER['DOCUMENT_ROOT']). En el caso de que el fichero PHP se encuentre fuera del directorio raíz de documentos, sólo se explorará su directorio.
En los ficheros INI estilo .user.ini sólo se reconocerán
las configuraciones INI que tengan los modos
INI_PERDIR y
INI_USER.
Las dos nuevas directivas INI, user_ini.filename y user_ini.cache_ttl controlan el uso de los ficheros INI de usuarios.
user_ini.filename establece el nombre del fichero que PHP buscará
en cada directorio; si se establece un string vacío, PHP no realizará ninguna búsqueda.
El nombre por omisión es .user.ini.
user_ini.cache_ttl controla con qué frecuencia se releen los ficheros
INI de usuario. El valor por omisión es 300 segundos (5 minutos).
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."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>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 :)
