PHP Code:
[0]=>
  array {
    
"id" => 11,
    
"rule"=> "rule 1"
  
},
[
1]=>
  array {
    
"id" => 40,
    
"rule"=> "rule 2"
  
}
[
3]=>
  array {
    
"id" => 55,
    
"rule"=> "rule 3"
  
}
[
4]=>
  array {
    
"id" => 40,
    
"rule"=> "rule 4"
  


How am I able to unset the elements with id = 40 to get the following array?

PHP Code:
[0]=>
  array {
    
"id" => 11,
    
"rule"=> "rule 1"
  
},
[
1]=>
  array {
    
"id" => 55,
    
"rule"=> "rule 3"
  

Do I need to do a foreach cycle / array check / unset?
Or is there any php function for it?
