从PHP数组中删除包含空格和换行符的元素

Question

I am facing problem to removing white space and new line from array element.

I have tried below code

$explode_string = explode("\n", $GetGroupListOutput);    
$new_array = array();
foreach ($explode_string as $value) {                
    $value1 = preg_replace('/\s+/', ' ', trim($value));        
    if(!empty($value1))
    {            
        $new_array[] = $value1;
    }
}
var_dump($new_array);

Output is like this

array(107147) {
  [0]=>
  string(10) ""
  [1]=>
  string(8) "
"
  [2]=>
  string(40) "Import Data"
  [3]=>
  string(9) "
"
  [4]=>
  string(6) ""
  [5]=>
  string(12) ""
  [6]=>
  string(13) ""
  [7]=>
  string(36) "All Masters"

My Output from api is like below.

  Import Data





    All Masters

     KRISHNA INTERIORS GSTR 3B






       -1

Above line show the output of my api. And output is not proper format.

The simplest operation to match "white space and new line" would be trim() , which makes it an easy filter operation:

$input = [
    "",
    "
",
    "Import Data",
    "
",
    " ",
    "  ",
    "   ",
    "All Masters",
];

$output = array_filter( $input, 'trim' );

var_dump( $output );
// array(2) { [2]=> string(11) "Import Data" [7]=> string(11) "All Masters" }
