Too many variables, too much time
Some people have this utter obsession with temporary variables. I just can't seem to understand it whenever I see something like:
Why the temporary variable? It is simply not necessary:
Unfortunately, it seems that many users have difficulty breaking out of this bad habit. Temporary variables slow down the execution time of your program. It's faster to omit them altogether and bundle the function calls together. Users who use temporary variables often add on 25% to the execution time of their scripts.

05:49 pm - Resource id #3
When I echo ed the following statement
$sendto1 = mysql_query("select email from yubmail where mail_alias = '$to'");
I got the message
Resource id #3
I thought it's an array so I tried mysql_fetch_array but did not get the expected results.
I checked using is_array function and found that it's not an arrary.
I tried a lot of other ways to find out what the actual value is.
At last (Should have done it first), I googled
"Resource id" php output
And the Forth result gave me the exact answer to my question.
It's a mysql issue and I have to add mysql_result function
$sendto2 = mysql_result($sendto1, 0);
I don't know how does adding one more layer helps, but it's working now.
I think open source and free software had no meaning if the powerful search engine like google was not there!

03:43 pm - Programmatically deciding which database to connect in PHP
After writing and debugging the code on my local machine, I would change the values of $user_name, $pwd and $database_name and upload the files to my client’s server. While I was developing the application (it was my first PHP project and I still maintain the program and the database for my client) there was no problem, as I would remember to change the values. But when, after the launch of the website, I routinely started altering the program (according to my clients interminably changing needs) I woud often forget to change the values, and consequently, render the website disfunctional. Then I changed the connect_database() function....
