Use PHP-version to switch PHP versions on macOS

The local environment is 7.1 that is consistent with the company's project environment, but laravel6.0 upgrade must require 7.2 (the local environment of some friends in the group is 7.2, and then the project dev environment cannot be automatically deployed after pushing the code), I think After thinking about it, I still have to make something locally that can easily switch the php version.

Method 1: Install php-version (if valet is not used, this should be possible)

#step 1. Use brew to install multiple php versions

brew install php71 // 原本有就不需要
brew install php72

step 2. If you find that the brew command to install php-version fails, then install it manually

[qian@bogon ~ ]$ mkdir $HOME/.local
[qian@bogon ~ ]$ cd $HOME/.local
[qian@bogon .local ]$ git clone https://github.com/wilmoore/php-version.git
[qian@bogon .local ]$ source $HOME/.local/php-version/php-version.sh
//测试  查看当前php版本
[qian@bogon .local ]$ php-version
* 7.1.18
 7.2.22

Now add environment variables

[qian@bogon ~ ]$ echo "source $HOME/.local/php-version/php-version.sh" >> ~/.zshrc
[qian@bogon ~ ]$ source ~/.zshrc

Switch php version

php-version 7.1

or

php-version 7.2

Using the command line to type php -v is already the switched version.

Method 2. Use valet use php@version (For friends who use valet to set up the environment, please read here)

This is actually because I didn’t read the document carefully - -, I have only roughly learned the basic use of valet before - -, if you read the documentation carefully, you can save half a day -

Valet allows you to use the valet use php@version command to switch PHP versions. If the specified version has not been installed, Valet will install the specified PHP version through Brew:

valet use php@7.2
valet use php

But this must be a new version of valet and must be upgraded first, otherwise an error will be reported, as follows

[qian@bogon ~ ]$ valet use php@7.2
  Command "use" is not defined.

valet Upgrade:

You can use the composer global update command in the terminal to update Valet. After the upgrade, if necessary, it is best (in practice, it is necessary) to run valet install again so that Valet can upgrade the configuration file.

composer global update
valet install

Then, it’s ok valet use php@7.2

[qian@bogon ~ ]$ valet use php@7.2
Stopping php@7.1...
Unlinking current version: php@7.1
Linking new version: php@7.2
Updating PHP configuration...
Restarting php@7.2...
Restarting nginx...
Valet is now using php@7.2.

trap record

1. Use brew for the first time to install php72 does not have enough permissions to create the Frameworks directory

An error occurred when executing it for the first time

==> Pouring python-3.7.4_1.mojave.bottle.tar.gz
Error: An unexpected error occurred during the `brew link` step
The formula built, but is not symlinked into /usr/local
Permission denied @ dir_s_mkdir - /usr/local/Frameworks
Error: Permission denied @ dir_s_mkdir - /usr/local/Frameworks

Then go to /usr/local/ to create a new directory Frameworks, and execute brew install php72 again. That is But

2. Use brew to install the php-version tool. The command fails.

brew install php-version

An error message is given

[qian@bogon ~ ]$ brew install php-version
Updating Homebrew...
==> Auto-updated Homebrew!
Updated 1 tap (homebrew/core).
==> Updated Formulae

==> Searching for a previously deleted formula (in the last month)...
Warning: homebrew/core is shallow clone. To get complete history run:

Error: No previously deleted formula found.
==> Searching for similarly named formulae...
Error: No similarly named formulae found.

Error: No formulae found in taps.

It says there is no such thing called "php -version", I also pulled "homebrew/core"

git -C "$(brew --repo homebrew/core)" fetch --unshallow

3. Execute php -v and report dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.61.dylib

[qian@bogon ~ ]$ php -v
dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.61.dylib
  Referenced from: /usr/local/bin/php
  Reason: image not found
[1]    66728 abort      php -v

Anyway, I just reinstall Dafa

brew uninstall --force php71 && brew install php71

4. php-version does not work in valet environment

If you don’t have friends who use valet, you don’t need to read the following~

As above Method one, php-version is installed, php -v also faces

but. . . . Regardless of whether you use sudo pkill -INT -o php-fpm or sudo kill -9 process id,

, you cannot kill the php-fpm process. Use ps -ef | grep php to view the process:

[qian@bogon ~ ]$ ps -ef |grep php
  501   307     1   0 四09上午 ??        51:34.33 /Applications/PhpStorm.app/Contents/MacOS/phpstorm -psn_0_90134
    0 70900     1   0  2:33下午 ??         0:00.11 /usr/local/opt/php@7.1/sbin/php-fpm --nodaemonize
  501 70901 70900   0  2:33下午 ??         0:00.00 /usr/local/opt/php@7.1/sbin/php-fpm --nodaemonize
  501 70902 70900   0  2:33下午 ??         0:00.00 /usr/local/opt/php@7.1/sbin/php-fpm --nodaemonize
  501 70904 10409   0  2:33下午 ttys007    0:00.00 grep --color=auto --exclude-dir=.bzr --exclude-dir=CVS --exclude-dir=.git --exclude-dir=.hg --exclude-dir=.svn php

Print phpinfo () in the code; It is still the previous php version after switching. You have to find the reason and find another way.

Use the sudo php-fpm command and find that the error is related to valet

[qian@bogon ~ ]$ sudo php-fpm && php -v
Password:
[16-Sep-2019 18:27:08] ERROR: An another FPM instance seems to already listen on /Users/qian/.config/valet/valet.sock
[16-Sep-2019 18:27:08] ERROR: FPM initialization failed
[qian@bogon ~ ]$

Then go I looked through the documentation and found out how to switch the php version of valet!
