About PHP

PHP is a popular server-side scripting language frequently used to develop web sites or command line scripts.

For information on integrating Apache with MySQL and PHP, see MAMP.

Versions

MacPorts includes several versions of PHP. You can install any or all of these versions simultaneously, though it is expected that you will only need to install one of them.

  • php71: PHP v7.1.x. This is the latest development version.
  • php70: PHP v7.0.x. This is the latest stable version.
  • php56: PHP v5.6.x. This is an older stable version.
  • php55: PHP v5.5.x. This is an older stable version.
  • php54: PHP v5.4.x. This version reached end of life in 2015 and is therefore not recommended.
  • php53: PHP v5.3.x. This version reached end of life in 2014 and is therefore not recommended.
  • php52: PHP v5.2.x. This version reached end of life in 2011 and is therefore not recommended.

This page shows how to install and use the php70 family of ports, but you can use another version if you prefer; all of these ports use a similar directory layout.

Step 1: Install PHP SAPIs

PHP comes in several Server APIs (SAPIs). You can install any or all of these that you need:

SAPI Port Install command
Command line php70 sudo port install php70
Apache 2 module php70-apache2handler sudo port install php70-apache2handler
FastCGI php70-cgi sudo port install php70-cgi
FastCGI Process Manager php70-fpm sudo port install php70-fpm

Step 2: Install PHP Modules

The SAPI ports contain the core PHP features, but there are many optional features available in separate ports, some of which you may want to install as well. Use port search php70 to see all the ports that are available.

Installing a PHP module automatically makes it available to all PHP SAPIs of the same PHP version.

For example, if you with to interact with a database server, here are some of the choices that exist:

Database server Port Install command
MSSQL php70-mssql sudo port install php70-mssql
MySQL, MariaDB, Percona php70-mysql sudo port install php70-mysql
ODBC php70-odbc sudo port install php70-odbc
Oracle php70-oracle sudo port install php70-oracle
PostgreSQL php70-postgresql sudo port install php70-postgresql
SQLite php70-sqlite sudo port install php70-sqlite

Step 3: PHP Configuration file setup

Set up your PHP configuration files. For development purposes use:

$ cd /opt/local/etc/php70
$ sudo cp php.ini-development php.ini

or for a production server:

$ cd /opt/local/etc/php70
$ sudo cp php.ini-production php.ini

then make changes to that newly created php.ini file - /opt/local/etc/php70/php.ini

Step 4: Install phpMyAdmin

Use MacPorts to install the latest version of phpMyAdmin.

$ sudo port install phpmyadmin

phpMyAdmin must be configured before it can be used. We do this in Step 5 below.

Step 5: Visit howto/MAMP for integration information

howto/MAMP must be consulted next for modifications to the Apache Configuration file to enable PHP and MySQL.

Trouble shoot

If by some reason the server still doesn't interpret PHP files (i.e. your web client tries to download them) it means the PHP configurations, as described at howto/MAMP#job1, are not taking effect. Typically, the file "Include conf/extra/mod_php70.conf" - is not being processed; the file is missing; or the contents incorrect. That file contains the two "AddType" lines below.

Verify your config file again!

Verify any changes you have made to the config file: /opt/local/apache2/conf/httpd.conf - The most common problem is that the files in the "extra" directory are not "readable" All files in that directory should be "-rw-r--r--"

$ /opt/local/apache2/bin/apachectl -t

This will return either "Syntax OK" or a specific line by line error listing.

The typical error message: "Could not open configuration file /opt/local/apache2/conf/extra/httpd-mod_php70.conf: Permission denied"

After correcting any config errors and saving the updated config file, simply run:

$ sudo port unload apache2

to stop apache (even though it is not running) and then start it using

$ sudo port load apache2

to start it again.

If the above fails to cause php files to be interpreted, you can edit the Apache httpd.conf file itself again and search for the block:

<IfModule mime_module>

And then add the following two lines before the end of that block.

AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps

Then restart the server.

As a last check, reboot and verify that everything has autostarted and is running (i.e., repeat the above tests).

Step 6: Configure phpMyAdmin

Edit the phpMyAdmin configuration file at /opt/local/www/phpmyadmin/config.inc.php.
A sample configuration file is installed at /opt/local/www/phpmyadmin/config.sample.inc.php.

Consult the documentation on your server at "/opt/local/www/phpmyadmin/doc/html/config.html"

NOTE: This option expects "/opt/local/www/phpmyadmin/doc/html" to be accessible under "<Document Root>." This can be accomplished by

$ cd <Document Root>
$ ln -s /opt/local/www/phpmyadmin/doc/html/ phpmyadmin-doc

and then accessing http://<servername>/phpmyadmin-doc/

Finally, you need to set up the phpMyAdmin configuration to access MySQL.

First create the config.inc.php file:

$ cd /opt/local/www/phpmyadmin/
$ sudo cp config.sample.inc.php config.inc.php

This will create a file config.inc.php in the phpMyAdmin directory.
Next, Edit that file, and locate the line:

$cfg['Servers'][$i]['auth_type']   = 'cookie';    // Authentication method (config, http or cookie based)? - default is Cookie.

It will be right at the beginning in the section labeled: "/* Authentication type */"

Change the value from 'cookie' to 'config'.

You will need to add the following two lines immediately after it.

$cfg['Servers'][$i]['user']        = 'root';      // MySQL user
$cfg['Servers'][$i]['password']    = '';          // MySQL password (only needed with auth_type = 'config')

Where ' ' is an empty password; fill it with your MySQL root password.
NOTE: You should change the 'auth_type' from 'config' to 'cookie' or 'httpd' so that you do not need to provide the password you selected for the MySQL root user in the 'password' option. (I.e. leaving it in plain text in this config file.)
However, as this is to simply get you "up-and-running," details for configuring those two authorization options are not given here. Details on "Using Authentication Modes" can be found at "https://docs.phpmyadmin.net/en/latest/setup.html#using-authentication-modes."

To check your phpMyAdmin installation, point your browser to http://localhost/phpmyadmin and verify that phpMyAdmin loads and can access your database (by providing a username and password, depending on the authentication method you selected).

Step 6: Install pmadb

Some consider the installation of pmadb "optional."
However, phpMyAdmin will flag the fact that it is missing and therefore certain features are not functional, with the message:

The phpMyAdmin configuration storage is not completely configured, some extended features have been deactivated. Find out why. 
      Or alternately go to 'Operations' tab of any database to set it up there.

For additional features provided by pmadb (http://wiki.phpmyadmin.net/pma/pmadb), first run

$ mysql -u root -p < /opt/local/www/phpmyadmin/sql/create_tables.sql

Next: create a file: mysql_phpMyAdmin_pmaSetup.sql - containing the following SQL code: (change the 'pmapass' to your password)

  • this is a one-time use scratch file so you can place it anywhere and delete it after use. (It is not included with the phpMyAdmin distribution.)

Note: In MySQL versions beginning with 5.6.7, there is no mysql.host table, so you will need to edit the SQL code below: (i) in lines 9 and 17 delete "Host," from the the GRANT SELECT commands; and (ii) delete the line 16 command "GRANT SELECT ON mysql.host TO 'pma'@'localhost';".

-- HOW TO USE THIS FILE (with MacPorts installation)
-- mysql -u root -p < /opt/local/www/phpmyadmin/examples/create_tables.sql
-- mysql -u root -p < mysql_phpMyAdmin_pmaSetup.sql

CREATE USER 'pma'@'localhost' IDENTIFIED BY 'pmapass';

GRANT USAGE ON mysql.* TO 'pma'@'localhost' IDENTIFIED BY 'pmapass';
GRANT SELECT (
    Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv,
    Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv,
    File_priv, Grant_priv, References_priv, Index_priv, Alter_priv,
    Show_db_priv, Super_priv, Create_tmp_table_priv, Lock_tables_priv,
    Execute_priv, Repl_slave_priv, Repl_client_priv
    ) ON mysql.user TO 'pma'@'localhost';
GRANT SELECT ON mysql.db TO 'pma'@'localhost';
GRANT SELECT ON mysql.host TO 'pma'@'localhost';
GRANT SELECT (Host, Db, User, Table_name, Table_priv, Column_priv)
    ON mysql.tables_priv TO 'pma'@'localhost';

-- Privileges
GRANT SELECT, INSERT, DELETE, UPDATE ON `phpmyadmin`.* TO 'pma'@localhost;

Then run this SQL to setup the pma 'controluser'

Finally, verify that the config file, at /opt/local/www/phpmyadmin/config.inc.php, is like this:
Note: The database name is pma underscore underscore -- two underscores!

/* User used to manipulate with storage */
// $cfg['Servers'][$i]['controlhost'] = '';                                                                                             
// $cfg['Servers'][$i]['controlport'] = '';    
$cfg['Servers'][$i]['controluser'] = 'pma';
$cfg['Servers'][$i]['controlpass'] = 'pmapass';
/* Storage database and tables */
// $cfg['Servers'][$i]['pmadb'] = 'phpmyadmin';

// $cfg['Servers'][$i]['table_coords'] = 'pma__table_coords';

// $cfg['Servers'][$i]['userconfig'] = 'pma__userconfig';                                                                               
// $cfg['Servers'][$i]['recent'] = 'pma__recent';
