Print array values | 易学教程

问题

I have

$finalprint[$counting] = $ppn.' '.$ppn2;

By using loop i have saved some data into the array. Now have also done the sorting.

arsort($finalprint); // i think this would arrange the data into descending order by $counting

Now I have data's like

$finalprint[426] = "XYZ"
$finalprint[124] = "ABC"
$finalprint[333] = "MNO"

How i can print the values of this array, like XYZ MNO ABC ?

回答1:

if you want to sort according to values in desc order

$finalprint[] = "XYZ";
$finalprint[] = "ABC";
$finalprint[] = "MNO";

rsort($finalprint);

foreach ($finalprint as $val) {
    echo  $val."&nbsp;" ;
}

o/p XYZ MNO ABC

if you want to sort according to keys in desc order

krsort($finalprint);

foreach ($finalprint as $val) {
        echo  $val."&nbsp;" ;
    }

o/p MNO ABC XYZ

回答2:

join(' ', array_values($finalprint));

回答3:

if you want to print the contents in your requested order, try ordering the array values. array_reverse helps:

$finalprint = array();
$finalprint[426] = "XYZ";
$finalprint[124] = "ABC";
$finalprint[333] = "MNO";
//sort by key ascending
asort($finalprint);
//getting the keys and reversinf them
$keys = array_reverse(array_keys($finalprint));
//iterating over the keys
foreach ($keys as $key) {
    echo $key.'=>'.$finalprint[$key].PHP_EOL;
}

回答4:

Use arsort to sort the values in reverse order or krsort to sort the keys in reverse order. (It is not clear from your example which one you want)

arsort($finalprint);
echo implode(' ', $finalprint);

Documentation : implode

回答5:

krsort( $finalprint );

echo join( " ", $finalprint );

But are you saying the array is sorted into XYZ, ABC, MNO order, or XYZ, MNO, ABC order?
