Sort multidimensional Array in PHP ascending

Question

I have an array which is inserted into an HTML Table

The problem is I want to sort it according to the value of counter. I tried an example which looks like this but it won't work.

foreach($analysis_data as $nr => $inhalt){
    $country[$nr] = strtolower($inhalt['country']);
    $counter[$nr] = strtolower($inhalt['counter']);
}

array_multisort($counter, SORT_ASC, $analysis_data);,

Does anybody know how to sort this multi dimensional array?

Yes there was a typing mistake but didn't changed the result — , Jul 21 '20 at 10:16

Due to the documentation third parameter of array_multisort function is array1_sort_flags. But you pass array with data.

I assume this is the right way to use it in your case.

array_multisort($counter, SORT_ASC);

$analysis_data  = array(
    array('counter'=>34,'country'=>'Germany'),
    array('counter'=>2,'country'=>'Vorarlberg'),
    array('counter'=>9,'country'=>'Oberoesterreich'),
    array('counter'=>5,'country'=>'Wien'),
    array('counter'=>3,'country'=>'Switzerland'),
    array('counter'=>6,'country'=>'Salzburg'),
    array('counter'=>1,'country'=>'Niederoesterreich'),
    array('counter'=>3,'country'=>'Czech Republic'),
    array('counter'=>1,'country'=>'Steiermark'),
);

foreach($analysis_data as $nr => $inhalt){
    $country[$nr] = strtolower($inhalt['country']);
    $counter[$nr] = strtolower($inhalt['counter']);
}

array_multisort($counter, SORT_ASC, $analysis_data);

Thanks but I want it ascending not descending. Keeping that out of mind, it doesn't work like this either — , Jul 21 '20 at 11:10
