Description

PHP (recursive acronym for PHP: Hypertext Preprocessor) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML.

WWW: http://www.php.net.

Requirements

The following application(s) must be installed, configured and running before PHP is installed:

Apache HTTP Server

Preparation for Installation

Start PuTTY on a Windows PC, Terminal on a Mac or similar terminal application on a Linux PC.

In this example Terminal on a Mac is used.

Open a remote SSH session to the server with:

Mac:~ user$ ssh user@192.168.1.4 [enter]

N.B.: Replace user@192.168.1.4 with User ID and IP Address on Your server!

[user@server ~]$

Enable superuser privileges with:

[user@server ~]$ sudo -s [enter]
Password: <-- passwd [enter]
[root@server /usr/home/user]#

N.B.: Enter user password, not the root password!

Installation

N.B.: Current version of Appache will be installed if missing!
Search for “mod_php” in the remote package repositories with:

[root@server /usr/home/user]# pkg search "mod_php" [enter]
mod_php56-5.6.30               PHP Scripting Language
mod_php70-7.0.20_1             PHP Scripting Language
mod_php71-7.1.6_1              PHP Scripting Language
[root@server /usr/home/user]#

In this example php71, php71-extensions and mod_php71 will be installed with;

[root@server /usr/home/user]# pkg install php71 php71-extensions mod_php71 [enter]

Message from apache24-2.4.26:
To run apache www server from startup, add apache24_enable="yes"
in your /etc/rc.conf. Extra options can be found in startup script.

Your hostname must be resolvable using at least 1 mechanism in
/etc/nsswitch.conf typically DNS or /etc/hosts or apache might
have issues starting depending on the modules you are using.

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

- apache24 default build changed from static MPM to modular MPM
- more modules are now enabled per default in the port
- icons and error pages moved from WWWDIR to DATADIR

   If build with modular MPM and no MPM is activated in
   httpd.conf, then mpm_prefork will be activated as default
   MPM in etc/apache24/modules.d to keep compatibility with
   existing php/perl/python modules!

Please compare the existing httpd.conf with httpd.conf.sample
and merge missing modules/instructions into httpd.conf!

Message from mod_php71-7.1.6_1:

Make sure index.php is part of your DirectoryIndex.

You should add the following to your Apache configuration file:


    SetHandler application/x-httpd-php


    SetHandler application/x-httpd-php-source


***************************************************************
[root@server /usr/home/user]#

Configuration

Create a configurations file for PHP from the recommended production template file with:

[root@server /usr/home/user]# cp /usr/local/etc/php.ini-production /usr/local/etc/php.ini [enter]
[root@server /usr/home/user]#

…and then edit /usr/local/etc/php.ini to meet your demands with:

[root@server /usr/home/user]# ee /usr/local/etc/php.ini [enter]

Got to line 663 and increase post_max_size from 8M to 32M;

; Maximum size of POST data that PHP will accept.
; http://php.net/post-max-size
post_max_size = 32M

Exit ee by pressing <esc> and save your changes.

Create an Includes configuration file, /usr/local/etc/apache24/Includes/php.conf, with:

[root@server /usr/home/user]# ee /usr/local/etc/apache24/Includes/php.conf [enter]

…and add the following text:

<IfModule dir_module>
    DirectoryIndex index.php index.shtml index.html
    <FilesMatch "\.php$">
        SetHandler application/x-httpd-php
    </FilesMatch>
    <FilesMatch "\.phps$">
        SetHandler application/x-httpd-php-source
    </FilesMatch>
</IfModule>

Exit ee by pressing <esc> and save your changes.

PHP Locale Settings

Display current active locale setting on the system with:

[root@server /usr/home/user]# locale [enter]
LANG=en_SE.UTF-8
LC_CTYPE="en_SE.UTF-8"
LC_COLLATE="en_SE.UTF-8"
LC_TIME="en_SE.UTF-8"
LC_NUMERIC="en_SE.UTF-8"
LC_MONETARY="en_SE.UTF-8"
LC_MESSAGES="en_SE.UTF-8"
LC_ALL=
[root@server /usr/home/user]#

You can list all UTF-8 locales on the system with:

[root@server /usr/home/user]# locale -a | grep '\.UTF-8$' [enter]

Locale settings for the server in this example is en_SE.UTF-8. This is a customized locale setting based on en_US.UTF-8 with modified TIME settings for 24h only display and with Swedish MONITARY and NUMERIC settings.

PHP will not read the locale settings when the charset type is appended to the locale name. ( ie: sv_SE.ISO8859-1, en_SE.UTF-8 ). The solution is to create a symbolic link to the selected locale directory.

Create a symbolic link to en_SE with:

[root@server /usr/home/user]# ln -s /usr/share/locale/en_SE.UTF-8 /usr/share/locale/en_SE [enter]
