$n = count($arr) -1;
for ($i = $n; $i >=0; $i–){
if (!trim($arr[$i]) // this solves: if 2,3 spaces in value?
array_splice($arr,$i,1);
}

// DONE
// remove _’s from email

for ($i = count($array) – 1; $i >= 0; $i–-)

Should be
$no = count($array);
for ($i = $no – 1; $i >= 0; $i–-)

tnx

Why not just use array_splice?
The script will look like

///////////////////////
//Cleanup array

for ($i = count($array) – 1; $i >= 0; $i–)
{
if ($array[$i] == “” || $array[$i] == ” ” || is_null($array[$i]))
array_splice($array, $i, 1);
}
//////////////////////////

Should be faster than copying all values from one array to another especially on large arrays.
