Hi my question is a little tricky, I got a 3-dimensional array and try to verify the 3rd level value and echo both 1st and 3rd level values. The following is the code example, and my failed approaches.

$myArray=array(
"mySub0" => arrary(
  0 => array("mySubSub0" => "1","mySubSub1" => "a"),
  1 => array("mySubSub0" => "2","mySubSub1" => "b"),
  2 => array("mySubSub0" => "3","mySubSub1" => "b"),
 ),
 "mySub1" => arrary(
  0 => array("mySubSub0" => "4","mySubSub1" => "a"),
  1 => array("mySubSub0" => "5","mySubSub1" => "a"),
  2 => array("mySubSub0" => "6","mySubSub1" => "a"),
 ),
 "mySub2" => arrary(
  0 => array("mySubSub0" => "7","mySubSub1" => "a"),
  1 => array("mySubSub0" => "8","mySubSub1" => "b"),
  2 => array("mySubSub0" => "9","mySubSub1" => "a"),
 ),
),

Ben "mySubSub1" değeri b olup olmadığını kontrol etmek istiyorum. Evetse, "mySubSub0" değerini ve dizinin ilk düzeyinde ilişkili anahtarı echo. Bu gibi olmalıdır:

mySub0
2
3
mySub2
8

Benim başarısız yaklaşım

 foreach ($myArray as $a => $b)
 {
 foreach ($b as $c)
 if($c[mySubSub1]=="b")
    {
        echo $a
        echo $c[mySubSub0];
    }
 else {
    }
 }

Sonuç, bir yinelenen mySub0 olacak

 mySub0
 2
 mySub0
 3
 mySub2
 8

Ben "echo $ a" "eğer" dışına taşırsanız

foreach ($myArray as $a => $b)
 {
 echo $a
 foreach ($b as $c)
 if($c[mySubSub1]=="b")
        {
        echo $c[mySubSub0];
    }
 else {
    }
 } 

sonuç olacaktır

 mySub0
 2
 3
 mySub1
 mySub2
 8

biri istenmeyen "mySub1" a değer b olup olmadığını doğrulamak için yer yok çünkü.

It has bothered my a lot today. I tried to Google but haven't found the right answer. Really hope someone can help me. Thank you in advance
