$input_array=array( 
array ( 'id' => 1,
'name' => "John Deo",
'class'=>"Four",
'mark'=>"75",
'sex'=>"female" ), 

array ( 'id' => 2,
'name' => "Max Ruin",
'class'=>"Three",
'mark'=>"85",
'sex'=>"male" ), 

array ( 'id' => 3,
'name' => "Arnold",
'class'=>"Three",
'mark'=>"55",
'sex'=>"male" ), 

array ( 'id' => 4,
'name' => "Krish Star",
'class'=>"Four",
'mark'=>"60",
'sex'=>"female" )
);
$names = array_column($input_array, 'name');
print_r($names);

Array ( [0] => John Deo [1] => Max Ruin [2] => Arnold [3] => Krish Star )

array_column ($input_array ,mixed $column_key [, mixed $index_key = NULL ] )

Example 2 with $index_key

$names = array_column($input_array, 'name','id');
print_r($names);

Array ( [1] => John Deo [2] => Max Ruin [3] => Arnold [4] => Krish Star )

$php_data_array = Array();
$result_set = $connection->query("SELECT * FROM student limit 0,4 ");// Generate resultset

while($row = $result_set->fetch_array(MYSQLI_ASSOC)){
//echo $row['id'],$row['name'],$row['class'],$row['mark']."<br>";
$php_data_array[] = $row; // Adding to array
}

$output = array_column($php_data_array,'name');

document.write(my_js_data_array[i]['class']); // List all class column
