Lucky Sevens — MySQL 5.7 and PHP 7


MySQL 5.7 and PHP 7 are the latest versions releases of two ofthe LAMP Stack pillars. In the past I have detailed how to use the MySQL apt-get repository to upgrade Ubuntu to the latest and greatest. But that about PHP 7? This is a fairly simple update for someone running a traditional LAMP (Linux Apache MySQL and PHP) server. There are also great directions out there on updating Nginx for those so inclined to be found with a quick search.

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:ondrej/php-7.0
sudo apt-get update
sudo apt-get purge php5-fpm
sudo apt-get install php7.0-cli php7.0-common libapache2-mod-php7.0 php7.0 php7.0-mysql php7.0-fpm php7.0-curl php7.0-gd php7.0-mysql
cp /usr/local/php7/libphp7.so /usr/lib/apache2/modules/

Then a quick test program:
<?php
$mysqli = new mysqli("localhost", "root", "hidave", "world");

/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}

/* print MySQL server version */
printf("

PHP version: %s

", phpversion());
printf("

MySQL version: %s

", $mysqli->server_info);
printf ("

System status: %s

", $mysqli->stat());

$mysqli->close();
?>

And the result:
PHP version: 7.0.0-5+deb.sury.org~vivid+1

MySQL version: 5.7.9

System status: Uptime: 2102 Threads: 1 Questions: 12 Slow queries: 0 Opens: 107 Flush tables: 1 Open tables: 26 Queries per second avg: 0.005

Please note that you will have to update your code if you use the old and no deprecated mysql calls instead of the supported mysqli calls.
