While loop in PHP: undefined offset

**Negative** · December 29th, 2002, 03:33 PM

I started studying PHP yesterday, and I'm facing a problem already...
Here's my code:

Code:

<html>
<head>
<title>Test array</title>
</head>
<body>
<?php
// Here I define my array
$assortiment = array("value1","value2","value3","value4","value5","value6");
// Here I just want to display my array using a while loop
echo "Arrays unsorted
";
echo "Assortiment: ";
$i=0;
while($assortiment[$i]){
  echo $assortiment[$i] . " ";
  $i++;
}
?>
</body>
</html>

This works, but keeps on returning this:

Arrays unsorted
Assortiment: value1 value2 value3 value4 value5 value6
Notice: Undefined offset: 6 in D:\ministry\testarray.php on line 13

Line 13 is the 'while'-line...

I tried Googling 'undefined offset', but all it returns are webpages facing the similar problem...

Anything I'm doing wrong? I'm running PHP 4.2.3 on Apache (Windows).

ok as promised fixed code
can't take credit tho - thank D`Amour (my housemate)

Code:

<html>
<head>
<title>Test array</title>
</head>
<body>
<?php
// Here I define my array
$assortiment = array("value1","value2","value3","value4","value5","value6");
// Here I just want to display my array using a while loop
echo "Arrays unsorted
";
echo "Assortiment: ";

for($i=0;$i<sizeof($assortiment);$i++) {
	echo $assortiment[$i] . " ";
}




//$i=0;
//while($assortiment[$i]){
//  echo $assortiment[$i] . " ";
// $i++;
//}
?>
</body>
</html>
