PHP Version and Location

If it’s installed, the version of PHP is obtained from this Terminal command:

php -v

If you get a response, see the Install section below.y

A Pretty Hypertext Preprocessor (PHP) was included by Apple on OS X (before MacOS):

On Mojave, the response was:

/usr/bin/php

Install PHP on macOS

1. Install using Homebrew:

   yes brew install php

3. The history of PHP releases are at:

   https://github.com/php/php-src/releases

4. Scroll down to the latest (largest) version for “OS X” and click “Download” of the macOS installer (.dmg), not a VM image from:

   https://www.apachefriends.org/download.html

   The most popular PHP development environment is XAMPP, an acronym of components:

   • Apache
   • MariaDB
   • PHP
   • Perl
     
     

   XAMPP is Windows-focused.

   WARNING: Don’s use XAMPP to develop Nextcloud which officially doesn’t support Windows. You’ll fight with PHP extensions (gd, mysqli, mbstring), mod_rewrite, and permissions.

   1. Click “Downloads” folder, then “Save” in the pop-up to store file such as “xampp-osx-8.2.4-0-installer.dmg”.
   2. Click the downloads icon in your browser and click the file you just downloaded.
   3. Double-click the “installer.app” file
   4. Let the pop-up.
   5. Click the Apple icon at the upper-left corner to open System Settings app.
   6. Click “Privacy & Security” in the menu.
   7. Scroll to the Security section. Next to the message that XAMPP was blocked, click “Open Anyway”. Again.
   8. Click Open Anyway and enter your password.
   9. The Setup app should pop up. In the XAMPP Setup Wizard, click “Next” repeatedly.
   10. Quit the installer app.

   Start

5. Start manager-osx.app (Application Manager) in ~/Applications/XAMPP From the CLI,

   open -a manager-osx.app
   

6. Click “Open Application Folder” xampfiles in a new Finder window.
7. Click “Managed Servers”, select “MySQL database” and click Start. Select “Apache Web Server” and click Start.

8. Click “Configure”. Notice the port defaults to 3306.

9. Verify it works: Open a browser and go to: http://localhost:3306

   You should see the XAMPP dashboard.

10. Start using CLI command (requires password entry):

    sudo /Applications/XAMPP/xamppfiles/xampp start && sleep 2 && echo "================ STATUS ================" && sudo /Applications/XAMPP/xamppfiles/xampp status
    

    or individually:

    sudo /Applications/XAMPP/xamppfiles/xampp startapache
    sudo /Applications/XAMPP/xamppfiles/xampp startmysql
    

11. CLI to check whether services are running:

    curl -sSI http://localhost/ | head -n 1     # Apache: expect "HTTP/1.1 200 OK" (or 3xx)
    nc -z -v localhost 3306                      # MySQL/MariaDB: "succeeded" = port open
    nc -z -v localhost 21                        # ProFTPD: FTP port
    

12. Install Visual Studio Code

13. Click “Configure”, then “Open Config file”. OK.
14. Can copy file to /etc/my.cnf to set global options.
15. ~/.my.cnf to set user-specific options.

16. from /Applications/XAMPP/xamppfiles/var/mysql) mysql-data-dir/my.cnf to set server-specific options

17. Sample program: Convert Celsius to Fareinheit temperature.

    $c = ($f - 32) * (5 / 9);
    echo $c from $f
    

PHP language basics:

• HTML files <h1>…</h1>
• commands between <?php ?> It’s also executed to HTML inside a // comment.
• comment code out as a block using /* */ tags

• semicolons after each statement

• Basic Error Handling

• Types
• Constants
• $Variables

• Numbers, Strings and Operators: single quotes between double quotes.

• Predefined Variables

• Attributes #[Attribute]

• Expressions
• Operators
• Conditionals

• Control Structures

• Functions

• Classes and Objects

• Enumerations
• Errors
• Exceptions

• Predefined Exceptions

• Functions
• Fibers (Fibers pause the entire execution stack, so the direct caller of the function does not need to change how it invokes the function. Fibers are full-stack, interruptible functions. May be suspended from anywhere in the call-stack, pausing execution within the fiber until the fiber is resumed at a later time.)

• Generators

• Loops

• Namespaces
• References Explained
• Predefined Interfaces and Classes
• Predefined Attributes

• Context options and parameters

• Arrays

• Loops

• Dependency Management with Composer

Activate PHP for Apache

To activate PHP using the Pico text editor that comes with Macs:

sudo pico /etc/apache2/httpd.conf

Within pico, press Ctrl+W and type php to search for the php5_module statement.

Press cursor key left to the right of the # comment character, press the backspace key to delete it. PHP is activated after you press Ctrl+X and Ctrl+Y to confirm Yes.

Alternately, to activate PHP using the vi text editor that also comes with Macs:

sudo vi /etc/apache2/httpd.conf

To find php…

Press ‘x’ over the ‘#’ character to delete it.

Type ‘:w!’ to save. Type ‘ZZ’ (upper case) to quit.

Only for Yosemite, also uncomment line 166:

LoadModule userdir_module libexec/apache2/mod_userdir.so

And also line 493:

#Include /private/etc/apache2/extra/httpd-userdir.conf

Activate php.ini

To activate PHP using the pico text editor that comes with Macs:

cd /private/etc

Copy the default file to a .ini file:

sudo cp php.ini.default php.ini

Enable Apache

For Yosemite only, open the file with:

sudo vi /etc/apache2/extra/httpd-userdir.conf

Uncomment line 16:

#Include /private/etc/apache2/users/*.conf

Save and exit.

Specify Mac User Name in Apache

Ensure that your user name is listed within:

ls -la /etc/apache2/users

In addition to the Guest.conf listed, there should be a .conf file with your Mac user name (mine is wilsonmar).

Such file may not be created while upgrading to Mountain Lion. Contents of this file is different on Yosemite:

<Directory "/Users/wilsonmar/Sites/">
AddLanguage en .en
LanguagePriority en fr de
ForceLanguagePriority Fallback
Options Indexes MultiViews
AllowOverride None
Order allow,deny
Allow from localhost
Require all granted
</Directory>

Establish Sites folder PHP website default file

By popular convention, the Sites folder (with a capital S) is used to store website files. Create one under the default /Applications folder from the command line:

mkdir ~/Sites

Create a HTML file to display by default when no file is specified:

echo “&LT;html>&LT;body>&LT;h1>My site works&LT;/h1>&LT;/body>&LT;/html>” > ~/Sites/index.html.en

/Library/WebServer/Documents/index.html.en . This contains the text “It works!”

Launch Apache

Older versions of Apache had a UI in System Preferences > Sharing and enable Web Sharing. But on Yosemite:

Within a Terminal:

sudo launchctl load -w /System/Library/LaunchDaemons/org.apache.httpd.plist

Check the version of Apache installed:

httpd -v

The response on my Yosemite is:

Server version: Apache/2.4.9 (Unix)

Server built: Sep 9 2014 14:48:20</tt>

Libmcrypt PHP

http://coolestguidesontheplanet.com/install-mcrypt-php-mac-osx-10-10-yosemite-development-server/

To add modules to PHP, add libmcrypt-2.5.8 and PHP source code from http://us.php.net/get/php-5.5.14.tar.gz/from/a/mirror using these instructions: http://michaelgracie.com/2011/07/21/plugging-mcrypt-into-php-on-mac-os-x-lion-10-7/
