Hello everyone, I'm creating a website in Joomla and I want to display some values from the database into the article but not in array form and for this I've used foreach but it's giving me Array to string conversion error

Answer 1

$value seems to be an array. Please check using var_dump. Echoing an array gives this error.

Answer 2

The array_values seems to be array. So create a recursive function to return string from your array. The code should be something like this

<?php

$db = JFactory::getDbo();

$query = $db->getQuery(true);

$query->select($db->quoteName(array('ques', 'options')));
$query->from($db->quoteName('logical_ques'));

$db->setQuery($query);

$result = $db->loadRowList();

print_r($result);

if (is_array($result)) {
    echo arrayToString($result);
} else {
    echo $result;
}

function arrayToString($array)
{ 
    foreach($array as $key => $value)
    {
        if (is_array($value))
        {
            $res .= arrayToString($value);
        } else {
            $res .= " ". $value;
        }
    }
    return $res;
}

?>
