Count array

[geckoo]

I have the following array:

 

Array ( [item0] => Array ( [0] => name1
                                         [1] => name2 
                                         [2] => name3 
                                         [3] => name4 
                                         [4] => name5 )

etc...

 

Is it possible to count the number of times a name exists in the compleet array?

 

Thanx in advance!

count

 

 

$arr = range(1,9);
echo count($arr); // 9

Thanx for the fast reply but i was maybe the following example is better:

 

 

Array ( [item0] => Array ( [0] => peter
                                         [1] => michael 
                                         [2] => kirsten 
                                         [3] => henry 
                                         [4] => james )
            [item1] => Array ( [0] => henry
                                         [1] => james 
                                         [2] => peter 
                                         [3] => brad 
                                         [4] => ford )

 

So what I need to know is how many times for instance name "james" is represented in the entire array. 

 

james = 2

peter = 2

henry = 1

etc...

array_count_values - did you even attempt to find this yourself? It was the second result on Google for "php count array".

[geckoo]

I did actually find it and try it, but couldn't get it to work. I do search before I ask. Sorry to upset you...

 

I think i'll have to take a look at the array.

I don't think array_count_values() will work, as it's a multi-dimensional array. You could maybe do this:

 

$total_count = array();
foreach($array as $values)
{
  $new_count = array_count_values($values);
  foreach($new_count as $key=>$count)
  {
    if(isset($total_count[$key])
    {
      $total_count[$key] += $count;
    }
    else
    {
      $total_count[$key] = $count;
    }
  }
}

$total_count will be an array of names with the count for each name.

Note: untested. may also not need the if/else statement (test it to find out). This may work:

$total_count = array();
foreach($array as $values)
{
  $new_count = array_count_values($values);
  foreach($new_count as $key=>$count)
  {
    $total_count[$key] += $count;
  }
}

I'm just not sure if the += sign works if the original array key isn't set. Maybe try the second block of code before the first.

Then I apologise for my remarks, geckoo
