Question

Form:
$headerValues=array();

$headerValues[1][2]="Test";
... 
....
echo "<input type=\"hidden\" name=\"ArrayData\" value=\"$headerValues\"/>";
echo "<input type=\"submit\" name=\"submit\" value=\"Submit\" />"; 

How do I read headerValues on FORM POST , I see as ARRAY when I use this code

foreach (array_keys($_POST) as $key) { 
   $$key = $_POST[$key]; 
   print "$key is ${$key}<br />";
   print_r(${$key}); 
} 

Answer 1

You can use:

$headerValues=htmlspecialchars(serialize(array('blah','test')));
echo "<input type=\"hidden\" name=\"ArrayData\" value=\"$headerValues\"/>";
echo "<input type=\"submit\" name=\"submit\" value=\"Submit\" />"; 

to get

$value = unserialize($_POST['ArrayData']);
