[RESOLVED] Counting matches in array, part 2

[TheWebWench]

A week or 2 ago, NogDog assisted on some perfect coding that I was struggling to figure out Thread here :

$types = array(); 
foreach($flower[1] as $type) 
{ 
  $types[$type] += 1; 
} 
echo "<pre>"; 
print_r($types); 
echo "</pre>\n"; 

This worked great for counting the like items and I can echo out the new array details as planned. But then I had to go and want to get a bit more complex.

Instead of just having 1 value to determine count, now i have 2. Using the prior example:

Array
(
[0] => Array
(
[0] => She likes Bob's lilacs!
[1] => She likes David's lilacs!
[2] => She likes Bob's carnations!
[3] => She likes David's lilacs!
[4] => She likes Mark's roses!
[5] => She likes Mark's carnations!
[6] => She likes Bob's daisies!
[7] => She likes Andy's daisies!
[8] => She likes Ed's lilacs!
[9] => She likes Anton's lillies!
[10] => She likes Jeremy's lillies!
)
[1] => Array
(
[0] => Bob's
[1] => David's
[2] => Bob's
[3] => David's
[4] => Mark's
[5] => Mark's 
[6] => Bob's
[7] => Andy's
[8] => Ed's
[9] => Anton's
[10] => Jeremy's
)
[2] => Array
(
[0] => lilacs
[1] => lilacs
[2] => carnations
[3] => lilacs
[4] => roses
[5] => carnations
[6] => daisies
[7] => daisies
[8] => lilacs
[9] => lillies
[10] => lillies
)

the ($key as $value) will work if I wanted to count Names or flowers - but I can not find information on if want $key to be determined by name AND flower, ie: have output to end up like:

Bob's lilacs: 1
David's lilacs: 2
Bob's Carnations: 1
Mark's Roses: 1
Mark's Carnations: 1
Bob's Daisies: 1
Andy's daisies: 1
Ed's lilac's: 1
Anton's Lillies: 1
Jeremy's lillies: 1

where both name and flower are they key, but separate variables. Hope this makes sense and someone can point me in the right direction again.

This will give you exactly what you want, OR a completely customizable array so you can search by person, or by flower:

<?php
$data = "She likes Bob's lilacs!
She likes David's lilacs!
She likes Bob's carnations!
She likes David's lilacs!
She likes Mark's roses!
She likes Mark's carnations!
She likes Bob's daisies!
She likes Andy's daisies!
She likes Ed's lilacs!
She likes Anton's lillies!
She likes Jeremy's lillies!";

preg_match_all("/She likes (.+?)'s (.+?)!/", $data, $flowers);
array_shift($flowers);

$cnt = count($flowers[0]); // Count array

// Names: $flowers[0]
// Flower: $flowers[1]
$types=$types2=array();
for($i=0; $i<$cnt; $i++)
{

/** /--\ types array /--\
 *  [Bob] => Array (
 *           [lilacs] => 1
 *           [carnations] => 1
 *           [daisies] => 1
 *         )
 *
 ** /--\ types2 array /--\
 *  [Bob lilacs] => 1
 *  [David lilacs] => 2
 */
	@$types[$flowers[0][$i]][$flowers[1][$i]] += 1;

@$types2[$flowers[0][$i].' '.$flowers[1][$i]] += 1;
}

echo '<pre>';
print_r($types);
echo '<hr>';
print_r($types2);
echo '</pre>';

?>

and another answer that saves the day. Thank you!

What would that be called please so I can learn exactly what you did there (multi-dimensional array?)? And any pointers on how to call out the 3 items where i need/want them? I'm able to call out the flowers & count in "types", but not "bob" (should say.. I know how to call out flowers & count, but not bob in a loop).

I've been reading through tutorials on multi-dimensional arrays (I believe that is what you just created there), but not really finding info to call to each bit.

tia!

Yes, I created a multi-dimensional array. Basically, to get the counts, you'd do the following:

<?php

// $types is still the large multi-dimensional array

foreach($types AS $name=>$counts)
{
  foreach($counts AS $kind=>$count)
    echo $name.'\'s '.$kind.': '.$count.'<br>';
}
?>

Basically, it's a double loop. First, loop through all the names. Then, loop through the child arrays associated with those names and output the counts.

Basically the above code would have the same exact effect as the $types2 array, except more customization can be done.

Works perfectly. Thank you for taking the time - at this point I 1/2 way understand it, and was able to fit it into my current script giving intended results. So much to learn... lol

thanks again!

Not a problem, it's what we're here for.
