Do you want to take over the original repo? https://github.com/sgotre/sphp-osx/blob/master/sphp i have no time to fix the bugs in there.

@rhukster would you be able to update your gist to include 7.3 as shown in the latest revision on my fork here: https://gist.github.com/csoseman/f53fc6dd70cf5a382b9fba7f84454961/revisions? 7.3 is now the default brew version for php. This script rocks so thanks for that!

I've now added 7.3 to this... thanks.

Thank you for that script!
Not use, but I think or the native osx apache module, there should be a check against the mac osx version. High Sierra ships with v7 and therefore won't find a php5 module. Wouldn't that cause a problem?

Probably with a directory check?

$FILE = "\/usr\/libexec\/apache2\/libphp7.so

if [ -e $FILE  ]; 
then
  native_osx_php_apache_module="LoadModule php7_module libexec\/apache2\/libphp7.so"
else
  native_osx_php_apache_module="LoadModule php5_module libexec\/apache2\/libphp5.so"
fi

Hi. I have an issue with homebrew: php links wrong, in services list "php" is written instead of "php@7.3".
Could you help me, please? The whole issue is on the homebrew forum

And I installed sphp from here

In my current httpd.conf I'm including a custom .conf file in which I load the php modules, so I had to modify the apache_conf_path to point to that file. Other than that it worked very well, thanks!

Is it normal that I have to reboot for the change to be effective ? The script works without any error but if I php -v I still get the previous version until I reboot

In your article (https://getgrav.org/blog/macos-catalina-apache-multiple-php-versions) httpd.conf is /usr/local/etc/httpd/httpd.conf

Why this file change "apache_conf_path" to "/etc/apache2/httpd.conf" ?

Hi! Works great! But I had to change this line:
sudo sed -i.bak "/$native_osx_php_apache_module/a\\
since Homebrew's Apache installed without a php module in the conf. (And if it did, it probably wouldn't be located at libexec/apache2/). Instead I used:
sudo sed -i.bak "/LoadModule rewrite_module lib\/httpd\/modules\/mod_rewrite.so/a\\

Hi !

Am I the only one who has a problem with the icu4c library version when I switch from version 5.6/7.1 to 7.2/7.3/7.4 ?

5.6 and 7.1 works with icu4u 63.1 and 7.2, 7.3 and 7.4 with 64.2?

Thank you in advance !

Hi!

FYI, I had problems with Apache restart, and solved them by changing the script to sudo apachectl -k restart (added -k).

I've updated the script to include the -k restart approach. I was having this myself and had updated locally, but not in the gist.

Hi !

Thank you in advance !

Hi @Sinepel,
I have the same problem. Have you found out a solution for this?

Thank you!
