The error is there is no variable named content like $content. Set the $content variable. Here it is:

$i = 0;
$content;
foreach ($value as $row) {
$content .= "<option value=\"" . $i . "\" " . $selected . ">" .$row . "</option>\n";
$i++;
      }

But there is no print result for above codes. What do you want for?
Do you want to print out the options. Try this

$i = 0;
echo "<select name=\"selectItem\">";
foreach($value as $row) {
echo "<option value=\"" . $i . "\">" . $row . "</option>\n";
$i++;
}
echo "</select>";

Good luck..

no i don't want to print out i got this covered it is the area that the script has a notice warring of undefined variable other wise it works fine im just trying to get the notice warring off there with out using error_reporting to hide the notice warring ok I'm using stackable variables for the print out so ya got that covered but that is where the error is occurring at on the foreach loop the stackable var is like example

$content .= "";

that were in the loop the notice warring is showing up on any var with the .= show up with the notice warring now can i get any help if i explained it well enough

It is the same below.

$content = "Hello From ";
//$content has the value "Hello From" string

$content .= "My PHP Page";
//Now, $content has the value "Hello From My PHP Page" string

It assign the variable to its value and another values. I can't explain very well because of I'm newer of PHP. Go there and it will teach you much more. Cheer..
