CodePudding user response：

There are a few things wrong with your code

1. All variables must start with a $
2. $meal = explode('-', $string, 2); you use $string again instead of $item
3. With PHP you've to concatenation strings with a . not with a
4. At the end of each line you've to place a ;

If you fix al those problems you get something like:

<?php
$string = "city-3|country-4";
$str1 = explode('|', $string, );
foreach ($str1 as $item) {
        $meal = explode('-', $item, 2);
        if ($meal[0]=="city")
        {
            echo "city duration    " . $meal[1];
        }
        else if ($meal[0]=="country")
        {
            echo "country duration   " . $meal[1];
        }
        echo "<br />";
}
?>
