[WTA] Multiple select form handling

Hello,

I'm newbie in programming, i have some code like this:

<FORM method="post" action="">
<SELECT multiple name="segment[]">
<OPTION value="1">Building & Industry</OPTION>
<OPTION value="2">Mechanical & Electrical</OPTION>
<OPTION value="3">Civil</OPTION>
<OPTION value="4">Oil & Gas</OPTION>
<OPTION value="5">Water Sanitation</OPTION>
<OPTION value="6">Dredging</OPTION>
<OPTION value="7">Tunnel</OPTION>
</SELECT>
<INPUT type="submit" value="submit">
</FORM>


<?PHP
$listvals=$_POST[segment];
$n=count($listvals);
echo "User chose $n items from the list.<br>\n";

for($i=0;$i<$n;$i++)
{
echo $listvals[$i]." ");
}
?>


And i get the result as an array( assumed i select option 2,3,4,5 ):

User chose 4 items from the list.
2 3 4 5

my big problem is... i need to keep the result as a variable. Let say that the varible we call as $allData, so the final result should be :

$allData="2 3 4 5";

i could send this variable to other pages or send it mysql...., how should i do so i could keep the array values to the variable.....

Please help me
Best Regards

 

$allData = implode(' ', (array)$_POST['segment']);
