How to remove empty values from array?

Question

Array (
      [0] => Angiogram - $10,000    
      [1] => 
      [2] => 
      [3] => 
      )

This is my array format and I need to remove all empty index from this array. I tried Using array_filter() but it is not working. Please help. I need result like:

Array([0]=> Angiogram-$10,000)

Then you don't have empty elements! What is the output of: var_dump($arr); ? — Rizier123

DEMO of array_filter() working for your array (as posted here) — Mark Baker

string(65) "" suggests a lot of hidden characters such as nulls in a 65-byte string, clearly it isn't empty — Mark Baker

Try this..

 $array=array("Angiogram - $10,000","","","","");
 $removeempty=array_filter($array);
 print_r($removeempty);

  or

$array = array_filter(array_map('trim', $array));
print_r($array);

    Ans:

    Array ( [0] => Angiogram - $10,000 )

Simplify even further to $myArray = array_filter($myArray, 'trim'); and eliminate the need to call array_map() completely

If array_filter($array) doesn't work it means that you array isn't empty!

Try this:

$array = array("1", "2", "3", "","5");


$clearArray = var_dump(removeEmpty($array));

function removeEmpty($array) {
  return array_filter($array, 'removeEmpty_internal');
}

function removeEmpty_internal($value) {
  return !empty($value) || $value === 0;
}
