Implode Inside For Loop

Question

I want to implode the multi array inside the for loop.

$_POST['PprodName'];

In this $_POST['PprodName'] I have got a value as:

Array ( [0] => steel mj23 [1] => [2] => [3] => [4] => [5] => [6] => [7] => )

steel mj23 is my first product name.

Now I want to check if the element is empty according to their position. so I applied a for loop but don't know how to implode element's which are not empty.

I want to implode only those element which are not empty.

Here is my for loop.

for( $i=0; $i < count($_POST['PprodName']); $i++ ) {
                    if( !empty( $_POST['PprodName'][$i] ) ) {
                        print_r($_POST['PprodName'][$i]);
                    }
                }

You don't need a for loop. Simply filter all empty values with array_filter() out and then you can simply use implode(), like this:

echo implode(", ", array_filter($_POST['PprodName']));

$result=Array();
foreach($data as $key=>$value)

  <?php
    $array = array(
        'fruit1' => 'apple',
        'fruit2' => 'orange',
        'fruit3' => ' ',
        'fruit4' => ' ',
        'fruit5' => 'apple');

        for ($i = 0; $i <  count($array); $i++) {
        $key=key($array);
        $val=$array[$key];
        if ($val<> ' ') {
           echo $key ." = ".  $val ." <br> ";
           }
         next($array);
        }


     /* fruit1 = apple
    fruit2 = orange
    fruit5 = apple
    */
    ?>
