Mac switch PHP version with php-version

In the development process, sometimes our program has very important limitations on a PHP version, especially for large projects.

Therefore, we need to switch multiple versions of PHP to meet our needs.

We use Php-version to achieve this goal.

First, we first use brew to install a php5.6, why not use the original php5.6 of the system?

This is because sometimes when upgrading the system, the PHP is configured to restore, so we use a new download php5.6.

Brew Install HOMEBREW/PHP/PHP56

After downloading, we first give php5.6 to unlink, otherwise our PHP7 is unable to install. will report the following error

Error:cannot install HOMEBREW/PHP/PHP70 because conflicting formulae is installed.  Php56:because different PHP versions install the same binaries. Please ' Brew unlink php56 ' before continuing. Unlinking removes a formula ' s symlinks from/usr/local. You canlink the formula again after the install finishes. Can--force Thisinstall, but the same build may fail or cause obscure side-effects in theresulting software

This time, we need to do something.

Brew Unlink Php56

Then we'll be able to download PHP7.

Homebrew/php/php70

Once downloaded, we can download the php-version.

Brew Install Php-version

You cannot use the php-version command directly at this time, you need to put the following sentence under the ~/.ZSHRC or ~/.BASHRC

SOURCE $ (Brew--prefix php-version)/php-version.sh && php-version 5

Then

SOURCE ~/.ZSHRC  or source ~/.BASHRC

Now if you execute php-version you'll see there are two PHP versions

?  ~  php-version  5.6.31* 7.0.22

With an asterisk indicates that you are using the php7.0, as long as you restart PHP, you can successfully switch PHP version
