one array from two by values php code example

Example 1: in array php multiple values

$haystack = array(...);

$target = array('foo', 'bar');

if(count(array_intersect($haystack, $target)) == count($target)){
    // all of $target is in $haystack
}

if(count(array_intersect($haystack, $target)) > 0){
    // at least one of $target is in $haystack
}

Example 2: php multiple array to single array

$array = array_column($array, 'plan'); 
// plan adalah nama kolom nya  
// $array adalah variable nya 
// semisal pengen membuat get data jadi single array bisa seperti ini 
     $CI = get_instance(); 
	 $DB1 = $CI->load->database('nama_db', TRUE);
	 $sql = "select dept from v_dept_distinct order by dept asc ";
	  $query=$DB1->query($sql);
	  // print_r(array_column($query->result_array() , 'dept')); 
	  return  array_column($query->result_array() , 'dept');
