Better Understanding PHP’s Garbage Collection. It’s interesting how just a few years can make a difference in the names that are given to things.
If this were to come up today, it would probably be called PHP Recycling Options, because rather than picking things up and throwing them into a landfill where they’ll never be seen again, we are really talking about grabbing things whose use has passed and setting them up to be useful again. But, recycling wasn’t le petit Cherie of society back when the idea was developed and so this task was given the vulgar name of ‘Garbage Collection’. What can we do but follow what history and common usage have given us? Program Generated Garbage Programs use resources; sometimes small ones, sometimes much bigger. When the program ends, naturally, the program, and any space that it has tied up, will disappear and the total space available will expand back to it’s maximum size.

Why is it better to develop in PHP with classes (OOP)? - PHP Classes blog. Introduction What are Object Oriented Programming Classes? Why it is better to develop your PHP projects using OOP classes?

Occasionally I have had trouble sending emails using the builtin mail() function in PHP.
Sometimes emails never reached their intended destination. Naturally I have assumed that there might be a problem with some spam filters used. However, lazy as I am, I have not given it a second thought. Instead I have used a PHP class that allows me to send emails using a remote smtp server using an account on that dedicated server. This has been a good solution for my setup anyways. The problem seems to be that PHP use the ini directive sendmail_from to set the from email address in the SMTP protocol. The simplest solution is to set the directive during execution: ini_set("sendmail_from", $email_from); $headers = "From: $email_from";mail($to, $subject, $message, $headers); The problem as well as the solution was already known by others.
