Question

I have a function that retrieves data from a Mysql database, stores the values in an array and returns that array to the calling function.

$stmt = $dbh->prepare("SELECT img_file_name FROM mjbox_images JOIN mjbox_posts USING (post_id) WHERE post_active = 0 AND post_id = ? ");
        $stmt->bindParam(1,$post_id);
        $stmt->execute();

        $resultarray = array();

        while($row = $stmt->fetch(PDO::FETCH_ASSOC)) {

                $resultarray[] = $row;
        }

        return $resultarray;

I am attempting to echo out the $values within that array like this:

$resultarray = get_post_data($post_id);

print_r($resultarray);

foreach($resultarray as $key => $value){
    echo 'The value is: '. $value . '<br />';
}

But when I browse the webpage it is only echoing out “Array”.
When I print_r the array the values are definitely in the array. So how do I correctly display those values?

Replace this line

$resultarray[] = $row;

with this:

$resultarray[] = $row['img_file_name'];
