I use textmate as my main php editor for mac. Once you get used with it, it will increase your productivity. Unfortunately, textmate doesn’t work with php very well out of the box. You must configure it and use the custom php bundle.

Here is how to get the custom bundle.

1) Open terminal

2) Execute the following commands:

mkdir -p /Library/Application\ Support/TextMate/Bundles

cd /Library/Application\ Support/TextMate/Bundles

svn co http://svn.textmate.org/trunk/Bundles/PHP.tmbundle

If you have textmate running, try to reload the bundle. You will see a new PHP bundle.

Subversion (svn) is a source control management tool. Each time we have finished with a certain task, we will need to commit our work (files and folders) to svn server. Each commit, the svn server will record the log and give a revision number. So in a simple use, we always have a backup of each revision. We can always back to any revision number and never lost our work.

The other use of svn is for a team collaboration. Each team member can change any files without worrying to overwrite other team member work. Svn can automatically merge modified files by other team member. With the revision log, project manager can easily track the progress and performance of each team member.

One of the common use of subversion is to get the difference between revision. This difference is important to create a patch. In web development, like in PHP script, patch is important for users so they do not need to re-upload and reinstall everything from the beginning again. Just apply the patch and run an upgrade sql query.

Okay, back to the difference / patch, here is what I usually do with svn and trac.

1) Go to trac page, browse source, and visit the main folder. Then click revision log.

2) Select the revision number, start from which number and end from which number. Click View change.

3) Scroll down until end of file, click Zip Archive

Today I need to add suffix to my css codes. Unfortunately I’m too lazy to do this repeated task again and again. With PHPDesigner, I tried to automate this task and with a little knowledge of regular expression now the problem is solved.

A quick explanation of regex that I use:

^\.([a-zA-Z\-]*)
- ^\. search for string start with .
- (…) capture the content inside with scope
- [a-zA-Z\-] only contain a-z, A-Z, and -
- * repeat the search condition [a-zA-Z\-] for next characters

\.$1_red
- \. write .
- $1 write matched string in the scope
- _red write _red

This morning I was so excited to start mining google trend. If you are new with Google Trend, it will show keywords that are recently getting popular. You will get 100 top popular keywords. This keyword list is updated every hour.

I’m planning to populate them, mining the data in order to get the ‘hot’ and long term profitable keyword that I can use to build adsense websites.

I will show you how to do this with a simple PHP script.
