HI I got so many empty & white-space element in array. anyone know how to remove it? IN PHP

```
$my[0] = ""
$my[1] = 5.21
$my[2] = 425
$my[3] = " "
$my[4] = " "
$my[5] = 75

```

I have used array\_filter to remove empty but still white-space How to remove that please any one told me ?

```
array_filter($my);  //Remove only empty array element
//My output is now
$my[1] = 5.21
$my[2] = 425
$my[3] = " "
$my[4] = " "
$my[5] = 75

//But i want only
$my[1] = 5.21
$my[2] = 425
$my[5] = 75

```

Please Help me to remove white-space.Thank you.
