The complete basics of PHP Tutorial 1

moitio · September 17th, 2004, 10:32 AM

This tutorial is based on teaching you the absolute basics of PHP code. It will show the structure of a PHP script

PHP Code:


			
<? //escapes the HTML document



//this is a comment and won't be parsed by the php

/* 

this

is 

also 

a 

comment 

*/



$variablename = "hello world"; //sets the variable: variablename to "hello world"



if($foo == "fee"){     //checks if the variable "foo" is set as "fee"

echo("hello world");  //prints hello world to the document IF "foo" equals "fee"

} //closes if statement

else{ //opens else statement 

echo("goodbye world"); //prints hello world to the document if "foo" DOES NOT equals "fee"

} //closes if statement



echo("hello world");  //prints hello world



//below: goes back to the HTML document

?>

This shows the basic structure of what a PHP code looks like.
PHP uses many different functions such as print, write, echo, and many many more, all of which can be found at http://uk2.php.net/quickref. Or if you have a function name just type in: http://www.php.net/(functionname)

Don't be frightened by all these functions. I'd be brain dead to say I knew each and every single one of them. I know the ones I use alot and if I ever need to use a different one, I just look it up.

This is quite alot of information, I understand, but take a long look at each bit, and learn what everything does.

I will be posting my next one in about a week about variables
