Missing ) -------------------+
In fact I forgot to mention that the string always starts at the start of the
line. So, I experimented a bit and the following works:
$onemore = preg_replace ('/^(>*From )/', '>$1', $line);
$oneless = preg_replace ('/^>(>*From )/', '$1', $line);
Thanks for the help.

Those versions are important ones. For the first time, you can
configure Apache (httpd.conf) and PHP (php.ini) directly from the
administration page. Thus, you can adapt easily the environment to
your needs.

EasyPHP is 11 years old now. It exists since 2000 (we were dealing
with PHP/Fi, PHP2 at this time). This is the first WAMP package ever
created.
EasyPHP can be installed anywhere : hard drive, USB drive...
You can also install modules (WordPress, Drupal, Joomla!, Prestashop,
Spip...). That means that you can install a version of WordPress,
Spip, Prestashop, Drupal... and test it immediately. It's
pre-configured. Perfect if you want to discover the last version of an
application.
Through the administration you can easily list the docroot,
extensions, change the Apache port, the timezone, max execution time,
error reporting, upload max filesize, add/remove alias, manage
modules...

Oooh, interesting! I will check out CakePHP! Thanks for tip! :)
I actually use my own framework. I needed a very light weight, flexible
framework. I designed it from the ground up to be very flexible and to use
AJAX and jQuery on the client side. If you'd be interested in check it out,
just let me know and I'll give you a link to the source code.
Take care,

Good article! I knew there was a reason why I never released mine but just
offer it up on occasion to someone who might find it useful! :)
Take care,

I quit using closing tags years ago and haven't looked back once
(except for code snippets, since explanatory text generally follows
the block).
