XAMPP - "Notice: Undefined variable"

[webdesignmad]

Hi. I installed xampp to practice php scripting. Until today, it has worked fine, but now it says:

Notice: Undefined variable: text in E:\xampp\htdocs\Experiments\Tutorial\HelloWorld.php on line 6

What can I do to fix this? I'm told that variable don't need to be defined before being initialized, but that doesn't really mean much to me!

Please help

Variables do not need to be defined before being initialized, but they do need to be defined before being called for use.  You are trying to use a variable called text, without it being set.  Without the code, there is no way to help you though.

 

$str = 'This is a string.'; //defined

if($text) { //text is not defined, and you will get a notice.
$text = 'More text.'; //text is now defined.
}

if(isset($fell_down)) { //fell down is not defined, but isset will keep it from throwing a notice. (empty will too).

Ah thanks very much. I've been looking for a solution to that for ages!
