How does virtPHP work?

Slide 30

Slide 30 text

First, we create the project folder ../{your env}/

Slide 31

Slide 31 text

../{your env}/ .virtphp bin/ etc/ lib/ share/ Then, we create root folders

Slide 32

Slide 32 text

../{your env}/ .virtphp bin/ activate composer composer.phar pear peardev pecl php php-config phpize etc/ pear.conf php.ini … Finally, we install a lot of files … lib/ php/ share/ pear/ cache/ cfg/ download/ temp/ tests/ www/ php/

Slide 33

Slide 33 text

../{your env}/ .virtphp bin/ activate composer composer.phar pear peardev pecl php php-config phpize etc/ pear.conf php.ini … bin/ is your applications … lib/ php/ share/ pear/ cache/ cfg/ download/ temp/ tests/ www/ php/
