PHP is a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML.

Installation

Install the php package from the official repositories.

A number of commonly used PHP extensions can also be found in the official repository:

# pacman -Ss php-

Setup

While PHP can be run standalone, it is typically used with http servers such as apache, nginx and lighttpd.

  • apache: to setup PHP, Apache and MySQL, commonly known as the LAMP, see LAMP article.
  • nginx: see Nginx page.
  • lighttpd: see Lighttpd article.

Configuration

The main PHP confiuration file is well-documented and located at /etc/php/php.ini.

Zend Core + Apache

Zend Core is the official PHP distribution provided by zend.com. It includes an installer/updater, zend optimizer, oracle support, and necessary libraries. However, it lacks support for postgresql, firebird, and odbc.

  • Install mod_fcgid (pacman -S mod_fcgid), a FastCGI module for apache (the official one sucks).
  • Install Zend Core (official php distribution)
    • Uninstall arch linux's php package.
    • Download and install zend core from [1] ; don't install the bundle apache or tell it to setup your web server. It always installs to /usr/local/Zend/Core due to hard-coded path.
    • Create a script /usr/local/bin/zendcore and create symlinks to php, php-cgi, pear, phpize under /usr/local/bin
      #!/bin/bash
      export LD_LIBRARY_PATH="/usr/local/Zend/Core/lib"
      exec /usr/local/Zend/Core/bin/`basename $0` "$@"
  • Setup Apache:
    • In /etc/httpd/conf/httpd.conf, add
      LoadModule fcgid_module lib/apache/mod_fcgid.so
      <Directory /srv/http>
      AddHandler fcgid-script .php
      FCGIWrapper /usr/local/bin/php-cgi .php
      Options ExecCGI
      Allow from all
      </Directory>
      SocketPath /tmp/fcgidsock
      SharememPath /tmp/fcgidshm
    • Remember to change the Directory path
  • Disable Zend Optimizer (so you can use cache):
    • Edit /etc/php.ini, uncomment the following line near the end of file:
      zend_extension_manager.optimizer="/usr/local/Zend/Core/lib/zend/optimizer"
  • Install APC (Alternative PHP Cache):
    • Run pear install pecl.php.net/apc as superuser.
    • Edit /etc/php.ini, add the line after "; Zend Core extensions..." (line 1205):
      extension=apc.so
  • Update Zend Core and/or install other components
    • Just run /usr/local/Zend/Core/setup

Development tools

Eclipse PDT

Eclipse PDT is not very complete at the current stage (v0.7); for instance, it cannot pop-up class list automatically when you type, though you can add custom auto-activation trigger keys.

You would need other plugins for javascript support and DB query.

Komodo

Good integration for PHP+HTML+JavaScript. Lacks code formatting and unicode support in doc comments.

Komodo IDE | Komodo Edit (free)

Add custom encodings:

  • Edit KOMODO_INSTALL_DIR/lib/mozilla/components/koEncodingServices.py, line 84, add:
 ('cp950', 'Chinese(CP-950/Big5)', 'CP950', '', 1,'cp950'),
 ('cp936', 'Chinese(CP-936/GB2312)', 'CP936', '', 1,'cp936'),
 ('GB2312', 'Chinese(GB-2312)', 'GB2312', '', 1,'GB2312'),
 ....

The format is (encoding name in python, description, short description, BOM, is ASCII-superset?, font encoding)

Zend Studio

Zend Studio is the official PHP IDE, based on eclipse. The IDE has autocomplete, advanced code formatting, WYSIWYG html editor, refactoring, and all the eclipse features such as db access and version control integration and whatever you can get from other eclipse plugins.

Zend Code Analyzer

A PHP code analyzer from Zend Studio. The program is indispensable for any serious PHP coding.

Installation

  • Download and install Zend Studio Neon
  • In the installation dir, run find . -name "ZendCodeAnalyzer to get the path.
  • Copy ZendCodeAnalyzer to /usr/local/bin/zca
  • Now you can remove zend studio; you won't need a key or anything.

Eclipse Integration

Error Link plugin:

  • Symlink zca to build.zca (so Error Link can recognize it)
  • Install Sunshade plugin suite;
  • Preference -> Sunshade -> Error Link -> Add: ^(.*\.php)\(line (\d+)\): ()(.*)
  • Run -> External Tools -> Open External Tools Dialog -> Select "Program" -> Clicn on "New":
    Name: Zend Code Analyzer
    Location: /usr/local/bin/build.zca
    Working Directory: ${container_loc}
    Arguments: --recursive ${resource_name}

Komodo Integration

Toolbox -> Add -> New Command:

  • Command: zca --recursive %F
  • Run in: Command Output Tab
  • Parse output with: ^(?P<file>.+?)\(line (?P<line>\d+)\): (?P<content>.*)$
  • Select Show parsed output as a list

Vim Integration

Add the following lines into your .vimrc:

autocmd FileType php setlocal makeprg=zca\ %<.php
autocmd FileType php setlocal errorformat=%f(line\ %l):\ %m

Troubleshooting

PHP Fatal error: Class 'ZipArchive' not found

Ensure the zip extension is enabled.

$ grep zip /etc/php/php.ini|extension=zip.so
