I'm hoping someone can help.
I have values in an array.. Let's say
$array = ("BMW", "BMW", "BMW", "AUDI", "AUDI", "FORD", "FORD", "FORD");
So I want to count the values. I can do that using array_count_values ($array);
This creates another array containing BMW => 3, AUDI => 2, FORD => 3
So what I want to do now is move BMW & FORD into another array because they occurred three times and leave AUDI behind.
Any ideas?
Many thanks in advance!
Since everyone is throwing around answers let me also not miss out.... In case you want only those brands that occur most frequent in $array you can simply use an array_filter to filter those that match the maximum number of occurrences. Finally you can extract those keys to obtain the brands through array_keys.
<?php
$array = array("BMW", "BMW", "BMW", "AUDI", "AUDI", "FORD", "FORD", "FORD");
$frequencies = array_count_values($array);
$max = max(array_values($frequencies));
// If you don't want to do this dynamically you can simply change the
// filter condition of course.
$filtered = array_filter($frequencies, function ($val) use ($max) {
// Since you mentioned you work with hard coded values,
// you could change it to
// return $val >= 3;
return $val === $max;
});
$filteredBrands = array_keys($filtered);
$allBrands = array_keys($frequencies);
// We can then exclude the filtered set
// from the entire set to separate them
// into two sets.
$difference = array_diff($allBrands, $filteredBrands);
print_r($filteredBrands);
echo '</br>';
print_r($difference);
echo '</br>';
This code will help you
First add the the element that we want in a new array ($newArray)
Then use the array_diff and update the first array
<?php
$array = ["BMW", "BMW", "BMW", "AUDI", "AUDI", "FORD", "FORD", "FORD"];
$countArray = (array_count_values ($array));
function youCondition($countArray, $element) {
return $countArray[$element] == 3;
}
$newArray = [];
for ($i=0; $i < count($array); $i++) {
// put any condition that you want here
if (youCondition($countArray, $array[$i])) {
$newArray[] = $array[$i];
}
}
// your new generated array
print_r($newArray);
$array = array_diff($array, $newArray);
// your updated array
print_r($array);
output
Array
(
[0] => BMW
[1] => BMW
[2] => BMW
[3] => FORD
[4] => FORD
[5] => FORD
)
Array
(
[3] => AUDI
[4] => AUDI
)
And you can change your condition ($countArray[$array[$i]] == 3) and make the different arrays
