我可以在Linux（Debian）中为各个文件夹设置php.ini吗？

Question

I'm new to PHP and server configuration in general, so I apologize in advance if this is a stupid question. Basically I have LAMP on my laptop (I installed Debian, Apache, MySQL, PHP separately, not as a bundle). The websites on my localhost are located in var/www/html/. I made a subfolder called 'php' (var/www/html/php/) where I'm learning and experimenting with PHP code.

Now, I made a php.ini file in var/www/html/php/ which only contains 2 lines:

display_errors = on
display_startup_errors = on

All I want is for the errors to display so that I know what I'm doing wrong. Anyway, that didn't work. So I moved the php.ini file to var/www/html/ but it still didn't work. In the end I had to go to the folder where PHP is installed and edit the php.ini file there (i.e. /etc/php5/apache2/php.ini).

I can see the errors now, but what if I don't want to turn on display_errors for every site in my localhost? What if I want to have display_errors=On for some folders and display_errors=off for some folders? How do I do that?

Answer 1

You can use the .htaccess php_value mechanism to modify php values.

For instance, having

php_value display_errors on

On your .htaccess will set this value for every file in that folders and every descending folders.
