Is this valid syntax?

[Karaethon]

$ARR[$i] == $NEEDLE ? $Count++ : $Count

I am using it in:

private function _countIf($ARR, $NEEDLE){ 
  $Count = 0;
  for($i = 0; $i < count($ARR); i++){
    $ARR[$i] == $NEEDLE ? $Count++ : $Count
  }
  return $Count;
}

I do not believe it is.  What results are you getting?

I just tried the syntax and it works. Have you tried it? Without knowing where $ARR and $NEEDLE come from and what they look like. It's hard to know what the problem is.

Havent yet tried it, its one method in a class im writing and it's callers are still under comstruction.

$ARR  is any array and $NEEDLE is a value you are trying to count occurances of.

Tho overall code works, the original version was

if($ARR[$i] == $NEEDLE){
	$Count++;
	}

but I thought the newer version cleaner

oops, not that it makes much of a difference but i mis-typed when i wrote it here it's

function countIf( $ARR, $NEEDLE){
  $Count = 0;         
  foreach( $ARR as $Entry){             
    $Entry === $NEEDLE ? $Count++ : $Count;
  }
  return $Count;
 }

Actually, I first thought it was valid but when first tried, it didn't work because of a typo.

try

function countIf($arr, $needle) 
{
    $counts = array_count_values($arr);
    return $counts[$needle] ?? 0;
}

CARP! I wrote countIf because all my searching of php documentation I couldnt find anything that let me search specific value.... I must have missed array_count_values, because it doesnt look for specific I moved on. I remember seeing it. arghhhh!

all i needed was

array_count_values(ARRAY)[VALUE IM LOKING FOR]

ONE FREAKIN LINE!!!!

Alternatively

function countIf($arr, $needle) 
{
   return count(array_keys($arr, $needle));
}
