hotsnoj, when you're all done can you post everything in a nice .txt file. Thanks!!!

I wanted to revive this. I've setup a Google Docs so we can collaborate on this document.

You can find the current document here: http://docs.google.com/View?docid=dd8btbzw_0dm8xsk

If you'd like to collaborate on this document, PM/Post your email address and I will invite you to edit. We can edit the document in real time if you'd like.

not allowed to modify the google doc:

//open php document
<?php //or
<script language="php">
//close php document
?> //or
</script>


//have code interpreted by html converter
echo 'statement to be converted'; //can include html,js etc statements

//switch
switch ($a) //int value
{
case 1: echo "case 1: \$a is $a<br>";break;
case 2: echo "case 2: \$a is $a<br>";break;
default: echo "neither case 1 or 2";
}

//type of variable
gettype($a) //if a = 3.14, displays 'double'

//type casting must become less significat (int from double)
$a = 3.14
&b = (int)$a //b is 3

//built in encryption
crypt($a) //most useful is $a is a string

//formatting:

%b
//binary value.

%c
//convert to int and print ascii

%d
//decimal value.

%f
//floating-point number.

%o
//octal value.

%s
//print as a string.

%X or %x
//hexadecimal value using uppercase letters.

//printf (same as C) displayed without interpreter
//print is also available
printf("$a and %b", $a); //displays $a then binary of $a from after ,
