Using return in foreach not echo with medoo

This is my example of my code i need to get work...

If i use " echo '...'; " everything is ok but if i use " return '...'; " i get only one record. The problem i dont want to use echo is i get all results on the top of my page. i need to use return because i call this function somewhere else on my page.

Thanks!

public function showForum()
{

$cats = $this->db->query("SELECT * FROM forum_cats ORDER BY cat_order ASC")->fetchAll();

foreach ($cats as $cat) {
return '<table class="table forum table-striped">
<thead>
<tr>
<th class="cell-stat"
style="background-image: url(\'\'); background-size: 50px; background-repeat: no-repeat; background-position: center;"></th>

Answer

Store all the data you want to return in a string, and later return the string:

public function something() {
    $result = ""; // Create empty string

    foreach($array as $val) {
        $result .= "something"; // Add something to the string in the loop
    }

    return $result; // Return the full string
}

An alternative (since you already have an array) would be mapping the array to your string values and returing the imploded the array like so:

public function something() {
    return implode('', array_map(function($val) {
        return "something";
    }, $array));
}
