Fatal error: Maximum Execution Exceeded in PHP

Problem: Using PHP you just encountered an error similar to the following:

Fatal error: Maximum execution time of 30 seconds exceeded

Solution: Just add these line of code in your PHP file

$durationInSeconds = 60;
ini_set('max_execution_time', $durationInSeconds);

The code above gives the maximum execution time of 60 seconds for your PHP script. Just be warned that your script may hog your system if it is running a heavy process for a long time.

In case you want your script to run in an unlimited amount of time, just set zero to $durationInSeconds:

$durationInSeconds = 0;
ini_set('max_execution_time', $durationInSeconds);

Notes Using git svn

Git is one thing and SubVersion (SVN) is another thing. Using git while working on an svn repository is yet another thing. Now here are my notes:

Go to master branch:

git checkout master

Get remote changes:

git svn fetch

Apply remote changes to master:

git svn rebase

Create new branch named dev:

git branch dev

Go to dev branch:

git checkout dev

Update dev branch from changes in master:

git rebase master dev

Update master branch from changes in dev:

git rebase dev master

Commit to svn repository:

git svn dcommit

Remove configuration files:

rm -rf ~/.gconf/apps/panel

Restart the Gnome panel:

pkill gnome-panel

Git svn in Ubuntu

It's time to familiarize more with git after working for years with SubVersion.

As my current project uses SVN, thank God git svn exists so I can practice more using git.

For future reference, here is a link for starting using git on svn repo in Ubuntu through git svn.

More Emails for Testing

Problem: Email is usually used as login username. There are times when you want to test a system by using several email accounts. And you usually need a lot more than the number of your existing email accounts. Now you think of opening another account from email providers.

Solution: With gmail, you can have only one account and use it with different addresses.

Here's how:
Assuming your email is myemail@gmail.com

Emails sent to the following:
myemail+001@gmail.com
myemail+002@gmail.com
myemail+003@gmail.com
myemail+010@gmail.com
... and so on

will be all sent to myemail@gmail.com.

Got the point?
Enjoy testing...
