I've got this array:

array(5) {
  [0]=>
  array(4) {
    ["nachricht"]=>
    string(9) "blablaaaa"
    ["user"]=>
    string(15) "334607943355808"
    ["datum"]=>
    string(16) "18.09.2014 11:13"
    ["deleted"]=>
    string(0) ""
  }
  [1]=>
  array(4) {
    ["nachricht"]=>
    string(3) "joo"
    ["user"]=>
    string(15) "334607943355808"
    ["datum"]=>
    string(16) "18.09.2014 11:56"
    ["deleted"]=>
    string(15) "334607943355808"
  }
  [2]=>
  array(4) {
    ["nachricht"]=>
    string(4) "noma"
    ["user"]=>
    string(15) "334607943355808"
    ["datum"]=>
    string(16) "18.09.2014 11:56"
    ["deleted"]=>
    string(0) ""
  }
  [3]=>
  array(4) {
    ["nachricht"]=>
    string(4) "test"
    ["user"]=>
    string(15) "334607943355808"
    ["datum"]=>
    string(16) "18.09.2014 11:56"
    ["deleted"]=>
    string(0) ""
  }
  [4]=>
  array(4) {
    ["nachricht"]=>
    string(4) "doh!"
    ["user"]=>
    string(15) "334607943355808"
    ["datum"]=>
    string(16) "18.09.2014 11:56"
    ["deleted"]=>
    string(0) ""
  }
}

I want to delete all sub arrays which include the value 334607943355808 in the key "deleted" in the sub array. I got this code:

if(($key = array_search("334607943355808", $array)) !== false) {
            unset($array[$key]);
        }

from: PHP array delete by value (not key) where it's non multi-array, but how can I do it in my case?

EDIT:

I tryed it this way now:

foreach($array as $delete){
      if(($key = array_search("334607943355808", $delete)) !== false) {
                unset($delete[$key]);
      }
}

But it's not working

you need recursion. –  Karoly Horvath Sep 18 '14 at 15:52

Use a nested foreach loop and check the values to see if they contain your number? –  TheOneWhoSighs Sep 18 '14 at 15:54
    
not as flexible, but in these case it will work just as well. –  Karoly Horvath Sep 18 '14 at 15:54
    
What you need is a FOREACH loop. –  Loenix Sep 18 '14 at 16:00
    
Look my edit, please help –  user2966167 Sep 18 '14 at 16:02

Just a simple foreach with a reference to the sub array:

foreach($array as &$sub_array) {
    if($sub_array['deleted'] == '334607943355808') {
        $sub_array = null;
    }
}

Or by key in the main array:

foreach($array as $key => $sub_array) {
    if($sub_array['deleted'] == '334607943355808') {
        unset($array[$key]);
    }
}

You can use array_map().Try this

$finalArr = array_map(function($v){
    if($v['deleted'] == '334607943355808') unset($v['deleted']);
    return $v;
}, $arr);
