PHP array_count_values multidimensional array

Question

i've got this array:

fffarray(2) {
 [0]=>
 array(1) {
 ["keyword1"]=>
 string(17) "Software Engineer"
 }
 [3]=>
 array(2) {
 ["keyword1"]=>
 string(10) "Hampelmann"
 ["keyword2"]=>
 string(17) "Software Engineer"
 }
}

i want an output like

fffarray(1) {
 ["Software Engineer"]=>
 int(2)
 ["Hampelmann"]=>
 int(1)
}

I really tried my best but can't achieve this.

May you please help me.

Thanks

Answer 1

if your array is always going to have only two dimensions, you might use this:

$finalArray = array();
foreach ($fffarray as $array)
 {foreach ($array as $key => $string)
 {$finalArray[$string] = $finalArray[$string] + 1;}}

this will count how many occurences of each value in all subarrays

Answer 2

Try building a new array that keeps count like this:

$newArray = array(
 array("Software Engineer"),
 array("Hampelmann", "Software Engineer")
);
$countArray = array();
foreach($newArray as $tempArray){
 foreach($tempArray as $key => $value){
 if(array_key_exists($value, $countArray)){
 $countArray[$value] = $countArray[$value] + 1;
 } else {
 $countArray[$value] = 1;
 }
 }
}
echo '<pre>'.print_r($countArray, true).'</pre>';

The output comes out like:

Array
(
 [Software Engineer] => 2
 [Hampelmann] => 1
)
