I have an online example of the progam at
http://www.recordconsulting.com/temp/shop.php. Each of the delete links use the
corresponding index values for the array, and use the unset() function to remove them.
While I'm here... how do I find the amount of information in an array? JavaScript
parlance would be $array.length.
Code is below:
<snip>
<?php
if($action == "delete") {
unset($item[$id]);
}
$color = "#336699";
var_dump($item);
for($counter = 0; $counter < 7; $counter++) {
$offset = $counter + 1;
echo "<tr><td width=\"80%\" bgcolor=\"$color\">\n";
echo "Item " . $offset . ": " . $item[$counter];
echo "</td>\n";
echo "<td width=\"20%\" bgcolor=\"$color\">\n";
echo "<a href=\"makelist.php?action=delete&id=$counter\"
class=\"link\">Delete</a>\n";
echo "</td></tr>\n\n";
if($color == "#336699") {
$color = "#6699CC";
} else {
$color = "#336699";
}
}
?>
</snip>
Thanks!

unset() works for this, how are you using it
exactly? Please post a short test script
that misbehaves for you.
$arr = array('foo','bar');
unset($arr[0]);
print_r($arr); // only $arr[1] = 'bar' exists now
