improve a little script

[Anon]

I have a script which says how many different names I have.

// array
$name[0] = "Tom";
$name[1] = "Bob";
$name[2] = "Tom";
$name[3] = "Poo";
// brains
unset($countednames);
$len=count($name);
for($i=0; $i<$len; ++$i)
{ ++$countednames[$name[$i]];
}
foreach($countednames as $name=>$count)
{ print("$name - $count (".$count*100/$len."%)");
}

Output:
Tom - 2 (50%)
Bob - 1 (25%)
Poo - 1 (25%)

But what would I do if I have an array like that:
$name[0][0] = "Tom";
$name[0][1] = "Bob";
$name[0][3] = "Tom";
$name[1][1] = "Poo";
How is it possible to make the script work with that kind of array?

P.S. Hayley Watson’s help is greatly appreciated!

Okay, you want all of them totalled across the whole two-dimensional array?

I'd replace the for($i...) with a pair of nested foreach()es and do the counting manually.

$count=0;
foreach($array as $row)
{
foreach($row as $name)
++$countednames[$name];
++$count
}
}

Now arrays with arbitrary numbers of dimensions might need a bit more work. Probably best done as a recursive function built around a single foreach loop; each array element is checked and if it is itself an array, the function calls itself, otherwise it does the ++ ++ bit.

function recursive_totals($array,&$countednames,&$count)
{
foreach($array as $item)
if(is_array($item))
{
recursive_totals($item,$countednames,$count);
}
else
{++$countednames[$item];
++$count;
}
}

(Totally untested code!)

...and call it with:

unset($countednames);
recursive_totals($array,$countednames);

recursive_totals($array)

PS: You're welcome!

...obviously the first code excerpt should read:

$count=0;
foreach($array as $row)
{
foreach($row as $name)
{
++$countednames[$name];
++$count;
}
}

that didnt work, i got a lot of error messages about missing arguments. how would i output the names and everything?

Ooh, I called the original array $array instead of $name.
And $count where I refer to it should be $len.

$array[0][0] = "Tom";
$array[0][1] = "Bob";
$array[0][3] = "Tom";
$array[1][1] = "Poo";

$count=0;
foreach($array as $row)
{
foreach($row as $name)
{
++$countednames[$name];
++$len;
}
}

foreach($countednames as $name=>$count)
{ print("$name - $count (".$count*100/$len."%)<br>");
}

$count=0; to make sense should be $len=0;
