Rob Allen's DevNotes

In the vein of some of Lorna's articles, this is more a note for myself than anything else. Not everything is explained in detail as it assumes you know how to use a command line...

These are the steps I take to get the Apple supplied PHP working with GD, PDO_MySQL and Xdebug working on OS X 10.5.

/usr/local

Ensure that the following directories exist:

    sudo mkdir /usr/local/include
    sudo mkdir /usr/local/bin
    sudo mkdir /usr/local/lib
    sudo mkdir -p /usr/local/man/man1

Run Apache in 32 bit mode

This saves us having to compile our own MySQL as MySQL doesn't offer a "fat" binary

1. cd /System/Library/LaunchDaemons
2. sudo vim org.apache.httpd.plist
3. Immediately after the line containing <array> add:

       <string>arch</string>
       <string>-i386</string>
   

4. Reboot

MySQL

1. Download the 32bit version of MySQL 5.0.x for OS X 10.5 from mysql.com and install the pkg, the startup item and the pref pane.
2. Add /usr/local/mysql/bin to the path: vim ~/.bash_profile and add:

       export PATH=~/bin:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH
       export EDITOR=vim
   

   at top of file. (Note that we set EDITOR whilst we are here so that svn is happy!)

3. Set up MySQL root password:

       mysqladmin -u root password {new-password}
       mysqladmin -u root -p{new-password} -h localhost password {new-password}
       mysqladmin -u root -p reload
   

   Quit Terminal to flush the history to file. Restart Terminal and remove the history file: rm .bash_history so that {new-password} isn't in plain text on the disk.

4. Set the correct socket information for PHP. Ensure MySQL is running via the System Preferences panel then:

       sudo mkdir /var/mysql
       sudo ln -s /tmp/mysql.sock /var/mysql/mysql.sock
   

Rest of Apache setup

1. cd /etc/apache2
2. sudo vim httpd.conf
3. Find #LoadModule php5_module libexec/apache2/libphp5.so and remove the leading #
4. Find AllowOverride None within the <Directory "/Library/WebServer/Documents">section and change toAllowOverride All so that .htaccess files will work.
5. Restart Apache: sudo apachectl restart
6. Open Finder and navigate to /Library/WebServer/Documents/
7. Create a new folder called "orig" and place all files currently in the Documents folder into it.
8. Create a new file called info.php with <?php phpinfo(); inside it.
9. Use Safari to navigate to http://localhost/info.php and check that the PHP version is displayed (5.2.6 at the time of writing).

php.ini

1. cd /etc
2. sudo cp php.ini.default php.ini
3. sudo chmod ug+w php.ini
4. sudo chgrp admin php.ini
5. vim php.ini (assuming your user is a member of the admin group) and change settings appropriately. Change:

       error_reporting  =  E_ALL | E_STRICT
       extension_dir = "/usr/lib/php/extensions/no-debug-non-zts-20060613"
   

   You must set the extension dir correctly. (Commenting the line out also works...)

PHP extensions

The supplied PHP doesn't come with pdo_mysql, pear or gd, so fix it.

1. Download the correct version of PHP from http://www.php.net/releases/. (5.2.6 at time of writing)
2. Create a directory called src in your home directory and unpack the PHP source. This creates /Users/rob/src/php-5.2.6/ in my case.

pdo_mysql

1. cd ~/src/php-5.2.6/ext/pdo_mysql.
2. phpize
3. MACOSX_DEPLOYMENT_TARGET=10.5 \
   CFLAGS='-O3 -fno-common -arch i386' \
   LDFLAGS='-O3 -arch i386' \
   CXXFLAGS='-O3 -fno-common -arch i386' \
   ./configure --prefix=/usr --with-pdo-mysql=/usr/local/mysql
4. make
5. sudo make install
6. Edit /etc/php.ini and find the extension_dir line and add after it:

       extension=mysql.so

7. Restart apache: sudo apachectl restart and check in the phpinfo that pdo_mysql is now loaded.

GD

Installing GD onto the stock PHP install that is supplied with OS X is slightly more complicated than you'd expect because you need to install libjpeg first.

Libjpeg

Libjpeg is available from the Independent JPEG Group.

1. Download the source code: http://www.ijg.org/files/jpegsrc.v6b.tar.gz
2. extract to ~/src
3. cd ~/src/jpeg-6b
4. cp /usr/share/libtool/config.* .
5. ./configure --enable-shared
6. sudo make install
7. Libjpeg is now installed in /usr/local/lib

GD extension

1. cd ~/src/php-5.2.6/ext/gd
2. phpize
3. MACOSX_DEPLOYMENT_TARGET=10.5 \
   CFLAGS='-O3 -fno-common -arch i386' \
   LDFLAGS='-O3 -arch i386' \
   CXXFLAGS='-O3 -fno-common -arch i386' \
   ./configure --with-zlib-dir=/usr --with-jpeg-dir=/usr/local/lib --with-png-dir=/usr/X11R6 --with-freetype-dir=/usr/X11R6 --with-xpm-dir=/usr/X11R6
4. make
5. sudo make install
6. Edit /etc/php.ini and find the extension_dir line and add after it:

       extension=gd.so

7. Restart apache: sudo apachectl restart and check in the phpinfo that GD is now loaded.

PEAR

1. cd ~/src/.
2. curl http://pear.php.net/go-pear > go-pear.php
3. Accept defaults, except for installation prefix (1) should be /usr/local
4. Check that the include_path in /etc/php.ini is correct and includes the PEAR directory (/usr/local/PEAR).

Xdebug

Can't have a PHP development environment without xdebug!

1. sudo pecl install xdebug
2. Edit /etc/php.ini and add

       zend_extension="/usr/lib/php/extensions/no-debug-non-zts-20060613/xdebug.so"

   after the other extension lines.

3. Restart apache: sudo apachectl restart and check in the phpinfo that xdebug is now loaded.

PHPUnit

1. sudo pear channel-discover pear.phpunit.de
2. sudo pear install phpunit/PHPUnit

It all works on this machines, anyway :)

Updatesee Marc Liyanage's PHP5 packages

A question came up on the phpwomen channel today about how to find the path to php executable for use in cron scripts. The answer that came back very quickly to use which or whereis.

It turns out that the server in question is a shared host with a control panel for access to cron and ftp to upload your files. A test proved that shell_exec() wasn't going to work too. After discussing it for a little while and trying a few combinations, we came up with putting:

echo `whereis php` > DIR/whereisphp.txt

into the cron script control panel and set it to run in 2 minutes time. Then it was just a case of looking in the file and discovering that the php binary was in /usr/local/bin.

And this post is here to save me a little bit of time when no doubt I'll run into the same problem in a year's time...

On Tuesday, PHPWM had a meeting at PSL Connect's offices where Darren Beale talked about Symfony.

I took a few pictures and have stuck them up on Flickr. I should have taken my other lens though as the 50mm isn't wide enough for taking pictures in room!

It was a very good talk that covered the basics of Symfony and what it can do. At the start, Darren asked us which frameworks we use and pretty much everyone used a different one! He then went though how Symfony worked and we got to see some code in action too. It was a nice step up from Ian's talk at the PHP UK Conference.

Afterwards we had a drink down the pub which was good :)

I don't often post links to articles I read via my RSS reader as I assume that most people who read this blog also read sites like Planet PHP, PHP Developer or DevZone.

Having said that, Etienne Kneuss has posted an article aimed at less experienced PHP programmers providing some quick guidelines to code cleanliness which are actually a very good reminder to us all.
