download a good editor, like crimson editor (built in ftp, not that it matters since you're using localhost) or notepad++. PHPedit has a pretty good trial period too, and has its own built in parser I believe, so you don't have to have php installed for basic php scripts. It checks scripts for errors on the fly too, which helped immensely during the learning process.
Once you've got easyPHP installed, and have one of those editors (or just use notepad), create a new file named whatever.php and put this in it:
<?php
$question = "Does PHPbuilder rock?";
$answer = "Yes!";
echo $question."<br />"; //displays the question, then a line break.
// Note the period between the variable and the text.
echo $answer;
?>
Save that file to wherever easyphp installed php's htdocs folder, then open the file up at http://localhost/whatever.php
Stare at the screen in amazement, and recognize that you are now part of the relatively low number of people in the World who can program in php.
