Question

i have a search engine for my page. as a result i would like to ouput the array key for each result.

so i have this code:

$results = search($keywords);
$results_num = count($results); //what shows the message how many items were found

if (!empty($errors){
foreach ($results as $result){
    echo "this is result: "
.$result['key'];       //thought would be the solution, its not.
    }
} else {
    foreach ($errors as $error){
        $error;
    }
}

i also tried using a counter like:

$results = search($keywords);
$results_num = count($results); //what shows the message how many items were found
$counter = 0;

if (!empty($errors){
foreach ($results as $result){
    $counter++;
    echo "this is result: "
.$counter;
    }
} else {
    foreach ($errors as $error){
        $error;
    }
}

what doesnt work as i thought and is still not that professional.
so if there is someone who could tell me how to solve this i really would appreciate. thanks a lot.

foreach ($results as $key => $result) {
  echo 'this is result: ' . $key;
}

The current key will be assigned to $key and the value for that property will be assigned to $result

In response to your comments, I think this is what you’re trying to achieve:-

$i=0;
foreach($results as $result) {
  echo 'this is result: ' . ++$i;
}
