PHP: Bridging the Gap Between Homebrew and Apache

When you installed mcrypt using Homebrew, you may encounter an issue where the PHP extension doesn't appear in your phpinfo() output. This discrepancy suggests that the PHP used by Apache differs from the version installed by Homebrew.

1. Verifying the PHP Difference

$ brew search php

This command will display a list of PHP versions available via Homebrew. Verify if the installed version is different from the one shown in phpinfo().

2. Configuring Apache to Use Homebrew PHP

a. Adding the PHP Module

$ brew install php@7.4

$ echo 'export PATH="/usr/local/opt/php@7.4/bin:$PATH"' >> ~/.zshrc

$ source ~/.zshrc

These commands install PHP 7.4, add its path to your environment, and reload your shell configuration.

b. Enabling PHP in Apache

Edit your Apache configuration file (typically named httpd.conf) and add the following lines:

LoadModule php_module /usr/local/opt/php/lib/httpd/modules/libphp.so

<FilesMatch .php$>

  SetHandler application/x-httpd-php

</FilesMatch>

Ensure that DirectoryIndex includes index.php:

DirectoryIndex index.php index.html

PHP configuration files can be found in:

/usr/local/etc/php/7.4/
