I'm actually stuck with a little problem. I want to use Laravel on my pi but it requires at least PHP 5.5.9.

But actually, the latest version of PHP that I am able to install (via the official repository) is the 5.4

How can I upgrade to 5.6 (or 5.5.9) ?

  • Looks like you will have to build it from source. – dhruvvyas90 Jun 21 '15 at 16:50

These are the steps you can follow.

  1. Grab latest source from this site. (http://php.net/downloads.php) Choose your nearest mirror. For example, I did "wget http://in1.php.net/distributions/php-5.6.10.tar.bz2"
  2. Unpack it: tar -xvjf php-5.6.10.tar.bz2
  3. cd php-5.6.10
  4. ./configure
  5. make -j4 (if you're compiling it on Rpi 2) else just make
  6. sudo make install
  7. Test it by firing php -v

It should be now upgraded to 5.6

Hope it helps.

  • Thank you for you post but for the very first time I'm not able to install it with this method. I don't know why but I think I've got a bug with the ./configure, it seems it does not work correctly because I am not able to use "make" (makefile is not created).

  • You will have to install related dependencies. See the error. Pi is missing libxml2. To install that, "sudo apt-get update && sudo apt-get install libxml2". Try configuring again. You may face other dependencies issues. You will have to install each on using "sudo apt-get install" before you can proceed with make. Hope it helps. – dhruvvyas90 Jun 22 '15 at 3:36

    Try : sudo apt-get install libxml2-dev – dhruvvyas90 Jun 22 '15 at 18:31

    Locate old php.ini file by "sudo find / -name php.ini" and copy the new one from php-5.6 directory by "sudo cp php.ini-production /path/to/php.ini" That should do, I guess. – dhruvvyas90 Jun 23 '15 at 19:23

At the time of this writing (november 2015), raspbian is built on Debian Jessie. The installable PHP version is in the 5.6 branch.

However, for Laravel projects you will need a number of PHP extensions. Most of these are available in the Raspbian repositories (or out of the box), but the php_mbstring extension cannot be loaded via apt-get.

Instead, to get php5_mbstring run apt-get install libapache2-mod-php5 which includes it (reference comments in http://php.net/manual/en/mbstring.installation.php)
