Store foreach loop values in a variable in PHP-CodePudding

I have a foreach loop in php. I want to store the output values of this loop in a variable. How can I do it? I want to store the given loop values in $my_variable

$my_variable = foreach( $orders as $order ){
    echo get_post_meta( $order->get_id(), '_tracking_box', true ).', ';
}

$my_variable should give direct values not the array

CodePudding user response：

Add the values to an array. Then use implode() to concatenate them into a string with , separators.

$tracking_array = [];
foreach( $orders as $order ){
    $tracking_array[] = get_post_meta( $order->get_id(), '_tracking_box', true );
}
$tracking_box = implode(', ', $tracking_array);
