Just to clear up:

Does the "!" used in some of those make things negative/false?

What does the "." that is used in some of your suggestions do?

"fish" . "cheese"

!$a also makes it false. Ie if $a contains 'true', some text, or a number but 0 it will become 'false'.

It's always good to make $a = NULL at the beginning to quickly ensure the _REQUEST values don't get mixed with your $a in some configs.

So is this PHP:

code:

---

echo 'some text'.$variable

---

the same as this JavaScript:

code:

---

document.writeln ('some text' + variable)

yea except you need a semi colon at the end of the php

code:

---

echo 'some text'.$variable;

Hmmm ... I always forget those . There should be one at the end of the JavaScript as well.

And except javascript runs on the browser, leaving all the execution in hands of the viewer and PHP runs on the server, hidden to all.

But the effect might be the same, yeah.
