How to correctly use `.user.ini`-file in PHP?

Question

In my working directory I have two files: index.php and .user.ini:

.user.ini:

display_errors=on

; http://be2.php.net/manual/en/filter.configuration.php#ini.filter.default
;filter.default = "full_special_chars"

index.php:

<?php
//ini_set("display_errors", "on");

// Use `.user.ini` file:
// http://php.net/manual/en/configuration.file.per-user.php
echo "Setting for 'user_ini.filename': " . ini_get("user_ini.filename");
echo "\n\n";


// It takes up to five minutes, until `.user.ini` is re-read:
echo "Setting for 'user_ini.cache_ttl': " . ini_get("user_ini.cache_ttl");
echo "\n\n";

// http://php.net/manual/en/function.ini-get.php
echo "Setting for 'display_errors': " . ini_get("display_errors");
echo "\n\n";
echo "Setting for 'filter.default': " . ini_get("filter.default");
echo "\n\n";

// php -S localhost:8000
// http://localhost:8000/

Using the above .user.ini-file (in my working directory) I expect the "Setting for 'display_errors': " having a value of on or 1, but it's empty.

How to correctly change settings using the .user.ini-file?

running php --ini results in

Configuration File (php.ini) Path: /etc/php5/cli
Loaded Configuration File:         /etc/php5/cli/php.ini
Scan for additional .ini files in: /etc/php5/cli/conf.d
Additional .ini files parsed:      /etc/php5/cli/conf.d/05-opcache.ini,
/etc/php5/cli/conf.d/10-pdo.ini,
/etc/php5/cli/conf.d/20-json.ini,
/etc/php5/cli/conf.d/20-readline.ini

which does not contain my .user.ini-file.

Explicitly adding the .user.ini-file works:

php --php-ini .user.ini index.php

but I'd like it to be automatically read when running the script from a given folder.

instead of use .htaccess for php config , u can create .user.ini file and put setting (without any indent or space) . for example my .user.ini config is:

max_execution_time =600
upload_max_filesize=200M
post_max_size=200M
memory_limit=256M
