| 1 | +# PHP Switch Scripts |
| 2 | + |
| 3 | +These scripts are designed to aid in the setup of and switching between multiple PHP versions in Ubuntu 16.04 LTS. |
| 4 | + |
| 5 | +Currently they support switching between PHP 5.6 and PHP 7.0. |
| 6 | + |
| 7 | +Please note that these scripts install packages from a third-party repository, provided by Ondřej Surý. More details are available at [the repository's PPA page on Launchpad](https://launchpad.net/~ondrej/+archive/ubuntu/php/). |
| 8 | + |
| 9 | +## Requirements |
| 10 | + |
| 11 | +* Ubuntu 16.04.* LTS |
| 12 | +* Apache 2.4.* |
| 13 | + |
| 14 | +You can check you have the required versions by running the following command. |
| 15 | + |
| 16 | +``` |
| 17 | +lsb_release -a | grep Ubuntu && apache2 -v | grep Apache |
| 18 | +``` |
| 19 | + |
| 20 | +Yuo should see something similar to the below. |
| 21 | + |
| 22 | +``` |
| 23 | +Description: Ubuntu 16.04.3 LTS |
| 24 | +Server version: Apache/2.4.18 (Ubuntu |
| 25 | +``` |
| 26 | + |
| 27 | +## Setup |
| 28 | + |
| 29 | +First, clone the repository, and change directory if you have not already done so. |
| 30 | + |
| 31 | +``` |
| 32 | +https://github.com/rapidwebltd/php-switch-scripts.git |
| 33 | +cd php-switch-scripts |
| 34 | +``` |
| 35 | + |
| 36 | +Next, to setup all the supported PHP versions and common PHP extensions for them, you just need to run the `setup.sh` script. This is shown below. |
| 37 | + |
| 38 | +``` |
| 39 | +./setup.php |
| 40 | +``` |
| 41 | + |
| 42 | +This may take some time depending on your system and connection speed. It will also require you to enter your password to install new packages. |
| 43 | + |
| 44 | +When you see a message similar to the following, setup is complete and you are ready to switch between PHP versions at will. |
| 45 | + |
| 46 | +``` |
| 47 | +* Setup complete. You may now use the 'switch-to-php-*.*.sh' scripts.` |
| 48 | +``` |
| 49 | + |
| 50 | +## Usage |
| 51 | + |
| 52 | +Once setup is complete, you can easily switch between different PHP versions using the appropriately named scripts. Examples are shown below. |
| 53 | + |
| 54 | +``` |
| 55 | +./switch-to-php-5.6.sh |
| 56 | +./switch-to-php-7.0.sh |
| 57 | +``` |
| 58 | + |
| 59 | +This will alter the versions of PHP running in Apache and the command line. Your password will be required to enable/disable Apache modules, restart the web server and altering the default PHP CLI version. |
| 60 | + |
| 61 | +## Verification |
| 62 | + |
| 63 | +If you wish, you can check that the switch was complete successfully. |
| 64 | + |
| 65 | +You can verify the command line version of PHP has changed with the following command. |
| 66 | + |
| 67 | +``` |
| 68 | +php -v | grep PHP |
| 69 | +``` |
| 70 | + |
| 71 | +You can check the version of PHP running in Apache by creating a new PHP file, that calls the `phpinfo()` method, then accessing it via a web browser. An example is shown below. |
| 72 | + |
| 73 | +```php |
| 74 | +<?php phpinfo(); ?> |
| 75 | +``` |
| 76 | + |
