Today very short, but I think helpful post about null coalescing operator. As I guess, you use a lot of if/else expressions in code. Sometimes we must check simple condition to set variable. There are two standard approaches. First, using if/else:Continue reading “PHP – Null Coalescing Operator”
We’ve already installed Nginx web server, PHP, run wrappers and configure php.ini settings. Next step will be some small improvements on global PHP-FPM configuration and also, additional settings on websites wrappers. Today we will edit /etc/php-fpm/version/fpm/php-fpm.conf file. It’s PHP-FPM main configuration file. Not PHP like php.ini from last chapter, but for FastCGI Process Manager. There is no time for unnecessary descriptions, let’s edit this file.
We already have a configured a Nginx web server and PHP-FPM wrapper. It’s time to change PHP default settings now – default configuration files from Ubuntu or Debian repositories aren’t bad, but we can make them better for our needs. In this chapter we will change only one file, php.ini, which should be located on /etc/php/YOUR_VERSION/fpm/ directory. Of course, fell free to use other settings than proposed on this blog entry.
This post will be very short. We must sometimes generate random password in PHP – for example when users create accounts on our service, or we send them new password after reset. Yes, we can do this in many ways, but most of them are bad solutions – we can create function (or method, class) to generate random string from given range, do it manually and try to make all random. But it isn’t random – it must by real secure, we must use cryptographically secure pseudorandom generator.
