Can you also make this update PHP_INI_SCAN_DIR? Like so:

# Calculate PHP_INI_SCAN_DIR.
export PHP_INI_SCAN_DIR=$(php --ini | grep "Scan for additional .ini files in:" | awk '{print $NF}')

Thanks for doing this! For me, the "non-root homebrew Apache" was running as root so I had to change line 76 (httpd -k restart > /dev/null 2>&1) to be "sudo httpd -k restart > /dev/null 2>&1". Maybe I've got something else wrong that's causing httpd to run as root but FYI to others. I thought it wasn't working properly when looking at phpinfo() refreshes but it was just that apache wasn't restarting.

The script is a great contribution, as an improvement, it also should update the current PATH, so the php version used on command line match the version used with apache, so the version used with composer or phpunit is the same as the used for the web server.

With this command the path will be updated, the trick it is to change php55 for the version loaded and in .bash_profile (or .bashrc), change it for a variable that match the current version.

export PATH="$(brew --prefix homebrew/php/php55)/bin:$PATH"

@wimleers I'm not sure what PHP_INI_SCAN_DIR is useful for but I can add it if you tell me where that should go

@crecabar I don't need to do that with homebrew. When the PHP version changes, it is applied globally. I use zsh though.

Great script, I've added a few modifications here: https://gist.github.com/moismailzai/765007c45f908085ec5807e4463606b1

Specifically, I've added a symlink to the currently active php.ini and am running tests for orphaned conf.d/*.ini files that are leftover by uninstalled modules and which cause php CLI to complain (thanks @benkmugo for the sed regex!). I've also added a check for homebrew mariadb, which gets stopped by the switching script and needs to be restarted. Feel free to include any of that in your gist.

PS, I don't think the check you do on line 73 is working correctly:

pgrep -f /usr/local/"Cellar|opt"/*/httpd 2> /dev/null > /dev/null

It looks like everything after "Cellar|opt" is being ignored (so the code block always runs). You can test in console:

Correctly yields 0 (non error status):

pgrep -f /usr/local/"Cellar|opt"/*/httpd 2> /dev/null > /dev/null    
echo $?

Incorrectly yields 0 (because no such process exists):

pgrep -f /usr/local/"Cellar|opt"/*/SOMETHINGTHATDOESNTEXIST 2> /dev/null > /dev/null    
echo $?    

Correctly yields 1 (error status):

pgrep -f /usr/localSOMETHINGTHATDOESNTEXIST/"Cellar|opt"/*/httpd 2> /dev/null > /dev/null    
echo $?
