MAMP is slow and doesn't match production server environments. macOS El Capitan ships with Apache built-in, so you can build a PHP development environment with Homebrew that's faster and more configurable.

This guide sets up PHP 5.6 with MySQL using the native Apache.

Why not the built-in PHP?

Apple's bundled PHP is outdated and locked to specific modules. Homebrew gives you:

• Control over PHP version and extensions
• Easy upgrades without waiting for macOS updates
• Access to the full PECL extension ecosystem
• Configuration that matches production Linux servers

Prerequisites

You need Homebrew. Install from brew.sh:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Installing MySQL and PHP 5.6

Install MySQL, PHP 5.6, and mcrypt (which many PHP frameworks require):

brew install mysql
brew install php56
brew install php56-mcrypt

Homebrew installs PHP to /usr/local/opt/php56 and puts the Apache module at /usr/local/opt/php56/libexec/apache2/libphp5.so.

Configuring Apache for Homebrew's PHP

macOS's Apache config lives in /private/etc/apache2/httpd.conf:

sudo nano /private/etc/apache2/httpd.conf

Find the rewrite_module line. It's commented out by default:

#LoadModule rewrite_module libexec/apache2/mod_rewrite.so

Uncomment it:

LoadModule rewrite_module libexec/apache2/mod_rewrite.so

This enables URL rewriting (most PHP frameworks need it for clean URLs).

Find the php5_module line referencing the old built-in PHP:

#LoadModule php5_module libexec/apache2/libphp5.so

Replace it with the Homebrew version:

LoadModule php5_module /usr/local/opt/php56/libexec/apache2/libphp5.so

Finding your php.ini

Homebrew's PHP config is at /usr/local/etc/php/5.6/php.ini. Adjust upload_max_filesize, memory_limit, or timezone there.

To find the active php.ini path:

php --ini

Starting MySQL and Apache

Start MySQL:

mysql.server start

Auto-start on boot:

brew services start mysql

Start Apache (requires sudo for port 80):

sudo apachectl start

Restart after config changes:

sudo apachectl restart

Open http://localhost in your browser. You should see the "It works." page.

VirtualHosts for local domains

VirtualHosts map custom domain names (like myproject.local) to specific directories. Cleaner than localhost/subfolder/ URLs.

Enable VirtualHost support in /private/etc/apache2/httpd.conf:

# Virtual hosts
#Include /private/etc/apache2/extra/httpd-vhosts.conf

Uncomment it:

# Virtual hosts
Include /private/etc/apache2/extra/httpd-vhosts.conf

Edit the VirtualHost config:

sudo nano /private/etc/apache2/extra/httpd-vhosts.conf

Add your site:

<VirtualHost cors.kahwee:80>
    DocumentRoot "/Users/kahwee/projects/cors"
    ServerName cors.kahwee
    ErrorLog "/private/var/log/apache2/cors.kahwee-error_log"
    CustomLog "/private/var/log/apache2/cors.kahwee-access_log" common
</VirtualHost>

<Directory /Users/kahwee/projects/>
  Options Indexes FollowSymLinks
  AllowOverride All
  Require all granted
</Directory>

• DocumentRoot points to your project's web root (for CakePHP, this might be webroot or public)
• ServerName matches the domain you want locally
• AllowOverride All lets .htaccess files work (needed for most PHP frameworks)
• Require all granted allows access to the directory

Adding the domain to your hosts file

Apache won't respond to cors.kahwee unless your system resolves it locally:

sudo nano /etc/hosts

Add:

127.0.0.1  cors.kahwee

Restart Apache:

sudo apachectl restart

Visiting http://cors.kahwee should load your project.

Testing PHP

Create a test file in your DocumentRoot:

echo "<?php phpinfo();" > /Users/kahwee/projects/cors/info.php

Visit http://cors.kahwee/info.php. You should see PHP's configuration page showing version 5.6.

Common issues

"403 Forbidden": Check the <Directory> permissions. Make sure Require all granted is set and the path matches your project directory.

PHP not executing: Verify LoadModule php5_module points to the Homebrew path, not the system path.

Changes not taking effect: Restart Apache after every config change: sudo apachectl restart

Why PHP 5.6 in 2016

PHP 7 shipped in late 2015, but many frameworks and plugins weren't compatible yet. PHP 5.6 was the safe choice for production work in mid-2016.

These days, I don't run PHP locally at all. Static site generators eliminated the need for dynamic server setups like this.
