apt-get install php5 on a Debian/Ubuntu server, you’ll notice that APT will automatically install a bunch of
apache2 packages as well. This can be pretty annoying if you’re planning on using another web server (or no web server at all).
If you take a look at the package dependencies (Debian/Ubuntu) you’ll see why this happens -
php5 needs one of either
php5-fpm. APT doesn’t care which package it installs; it just picks the first package that satisfies the dependency, which is why you get the

php5. For example,
apt-get install php5-fpm php5 or
apt-get install php5-cgi php5.
After upgrading php-fpm, my PHP-based sites were returning “502 Bad Gateway” errors. This can happen when the php5-fpm package reconfigures itself to listen on a different socket. Here’s how you can solve it.
Check to make sure that php-fpm is running with
ps aux | grep php - if you can’t see any php-fpm processes in the output, then you may need to re-install php-fpm. If php-fpm is running okay, then skip this first step.
sudo apt-get remove php5 php5-cgi php5-fpm
sudo apt-get install php5 php5-cgi php5-fpm
The thing to notice here is that the order in which you install the packages is important. In the past I have found that installing them in the wrong order causes the packages to be configured incorrectly.
Next, get php-fpm to listen on the correct host/port. In
/etc/php5/fpm/pool.d/www.conf change the
listen value to match the
fastcgi_pass location in your Nginx configuration. For example, I changed mine from:
listen = /var/run/php5-fpm.sock
If you are configuring php-fpm to listen on a Unix socket, you should also check that the socket file has the correct owner and permissions. While I wouldn’t recommend it, you can simply give read-write permissions to all with
sudo chmod go+rw /var/run/php5-fpm.sock.

sudo service php5-fpm restart and everything should work normally again.
It’s debatable whether or not it’s good practice to use short syntax in PHP. I personally prefer to use short syntax because it keeps my view files looking tidy.
The regular expression below will find all one-liner
echo statements (e.g.
<?php print $var; ?>) and convert them to
<?= $var ?> statements. It will not match statements containing closing brackets, for example when using ternary operators:
<?= ($foo == $bar) ? 'Foobar' : 'Foo' ?>
