UPDATE: There is now an easier way to change your PHP version. Just login to your Bluehost control panel and go to “PHP Config”, select PHP 7 and click “Save Changes”.
UPDATE: This is no longer required to use PHP 7 as Bluehost has put PHP 7 on their servers. You can now put one of these directives in your .htaccess file depending on how you want PHP configured. If you don’t know what these do, just go with the first one.
AddHandler application/x-httpd-php70 .php for regular PHP
AddHandler application/x-httpd-php70f .php for FastCGI
AddHandler application/x-httpd-php70s .php for Single ini
I’ve been hearing about all these speed increases from lower PHP versions to PHP 7, so I thought I’d see if I could get it compiled on my Bluehost shared account. I was able to get it compiled and running, but I haven’t done any speed comparisons yet. I’ll just show you how I got it compiled for now. To follow this, you have to have SSH access enabled. You can find instructions for that here.
Once you’re ssh’d into your account, go to your local bin directory. and download the PHP 7 tarball.
$ cd ~/bin
$ wget http://us3.php.net/get/php-7.0.0.tar.gz/from/this/mirror
Then unpack the .tar.gz and move into the PHP 7 directory.
$ mv mirror php7.tar.gz
$ tar -xvzf php7.tar.gz
$ cd php-7.0.0
Here’s where we configure, make, and make install PHP 7.
$ ./configure --with-config-file-path=/homedir/username/etc/php/ --with-config-file-scan-dir=/homedir/username/etc/php/conf.d/ --enable-mysqlnd --with-curl --with-openssl --with-readline --with-recode --with-zlib --with-mysqli --prefix=/homedir/username/bin/ --enable-mbstring --with-gd
$ make -j"$(nproc)"
$ make install
Note: Make sure to change “/homedir/username/” to your homedir and username. You can get this with
pwd. Additionally, this is compiled with only a few options. You can compile with whatever options you’d like.
Now that we have PHP 7 compiled and installed, test the binary. Make a PHP file with the following:
Then run it.
$ ~/bin/bin/php filename.php
You should see the output “ok”. The final step is to make .htaccess run your PHP files with PHP 7. Change to whatever directory you want PHP 7 to run in and make a symlink to your php binary.
$ cd ~/public_html
$ ln ~/bin/bin/php-cgi cgi-bin/php
Then drop the following in your .htaccess file:
Action application/x-httpd-php7 /cgi-bin/php
And there you go. Whatever site is in that directory is now running on PHP 7.
A few notes. This isn’t exactly a great way to get on PHP 7, I’m just showing that it’s possible. If you do decide to do this, I’m not responsible for your actions. Use this with caution.
