Question

I have an array of objects:

$obj = array();

// add the new items
$row = new stdClass();
$row->first = $first;
$row->last = $last;
$row->phone = $phone;

$obj[] = $row;

Now, if I only have the value of $last, is there a way to delete the entire $row object without specifying each key/value?
(If it helps to understand, if it was a mysql statement it would be something like “DELETE * FROM $obj WHERE $row->last = ‘Thomas’ “)

thx

Answer 1

You need to know the key. However, if you iterate through the array you can find it.

/* Your original code: */
$obj = array();

// add the new items
$row = new stdClass();
$row->first = $first;
$row->last = $last;
$row->phone = $phone;

$obj[] = $row;

/* My addition: */
$theOneToDelete = $last;
foreach ($obj as $key => $row) {
   if ($row->last == $theOneToDelete) {
      unset($obj[$key]);
      break;
   }
}

There may be a terser approach with some of the array_* functions, but this lays it out.
