How to overwrite some PHP defaults configuration?

Question

Let's said that I have installed PHP 5.5.x in Ubuntu and it comes with a default configuration. I would like to overwrite a few configurations but I do not want to (this is how I know it's possible):

• edit the default php.ini file
• use a PHP block in each .php file to overwrite them
• use .htaccess files and directives

I would like to create a file named custom-php.ini with the following lines (as an example):

; Basic configuration override
expose_php = Off
memory_limit = 512M
post_max_size = 128M
upload_max_filesize = 128M
date.timezone = UTC
max_execution_time = 120

; Error reporting
display_errors = stderr
display_startup_errors = Off
error_reporting = E_ALL

; A bit of performance tuning
realpath_cache_size = 128k

; OpCache tuning
opcache.max_accelerated_files = 32000
; Temporarily disable using HUGE PAGES by OpCache.
; This should improve performance, but requires appropriate OS configuration
; and for now it often results with some weird PHP warning:
; PHP Warning:  Zend OPcache huge_code_pages: madvise(HUGEPAGE) failed: Invalid argument (22) in Unknown on line 0
opcache.huge_code_pages=0

; Xdebug
[Xdebug]
xdebug.remote_enable = true
xdebug.remote_host   = "192.168.3.1" // this IP should be the host IP
xdebug.remote_port   = "9001"
xdebug.idekey        = "XDEBUG_PHPSTORM"

Is there any place where I can write this file and default PHP values gets overwrited by the ones on custom-php.ini?

是的，应该是可以的。首先，在您的文档根目录中的某处创建一个 PHP 文件info.php并将其放入<?php phpinfo() ?>。然后从浏览器调用它并查找Scan this dir for additional .ini files. 在 Ubuntu 上，它可能类似于/etc/php5/apache2/conf.d.

在该目录中，您可以放置​​自己的自定义 ini 文件（将其命名为99.overrides.php.ini），以便最后对其进行解析。

在该文件中，添加您想要的任何其他配置，重新启动 Apache 或 Web 服务器，更改将生效。
