Entirely remove empty array

Question

I'm using a foreach to build this :

array (size=3)
  'trainid' => string '76795' (length=5)
  'traintype' => string ' -X' (length=3)
  'userid' => string 'CPN' (length=3)

array (size=3)
  'trainid' => string '27725' (length=5)
  'traintype' => string ' -Z' (length=3)
  'userid' => string 'CPN' (length=3)

array (size=0)
  empty

array (size=3)
  'trainid' => string '00000' (length=5)
  'traintype' => string ' -X' (length=3)
  'userid' => string 'CPN' (length=3)

array (size=3)
  'trainid' => string '27921' (length=5)
  'traintype' => string ' -Z' (length=3)
  'userid' => string 'CPN' (length=3)

And as you see, there is an empty array and I would like to entirely remove this array. In fact, it crashs my sql script if there is an empty array.

Do you know how to remove it?

Thank you!

You can use array_filter, if no callback is provided, all entries equal to FALSE will be removed.

$array2 = array_filter($array);

Already tried. Using this does not remove the empty array. – FabriceDouceur Oct 07 '15 at 08:18
Can you copy the content of `var_dump($array)`? – Kristian Vitozev Oct 07 '15 at 08:22

Simply use array_filter(), It will automatically remove empty variable in array..

   print_r(array_filter($arrayvariable));
