Oh man Jeffrey, I needed this really bad. One thing that I still have yet to master/learn and don’t look forward to is regular expressions. I suppose now is a better time then ever…

Hey David – it’s not as hard as it looks.
I promise. I have a more extensive article coming out later this week (Thursday) which should help as well.

Hey Jeffrey, loving the videos especially about this topic. It can be so powerful once you grasp the findementals.
If you can, it would be nice if you could do a short video tutorial on how to apply this on .htaccess files for redirecting, clean urls etc.
Keep up the good work.

As you have told in the beginning,
“this series has been transferred to Nettuts+ from our sister site, ThemeForest.”
I would like the actual ThemeForest links for all 5 video, so i can go there and see the actual comments that users had made.
I hope it can help us.

How come I get an error.
undifined variable? I think I am ready to retire. I’ll go and bother my wife for few hours. Maybe, That makes me happy for a while. Stress!!
$test = ‘model1=David1&listed1=555.00&net1=555.00&model2=David1&listed2=555.00&net2=555.00′;
preg_match_all(‘/-\d+\=/i’, $test, $sorted_new);
foreach($sorted_new[1] as $str) {
( )echo $str.”";
}

David, you search for matches[1], but no “()” was defined in pattern
close the sting in () what you want…
