If you use custom field in wordpress, sometime need run the custom field into some function.

<?php
$cars=array("Volvo|100","BMW|100","Toyota|100"); 
foreach($cars as $key => $value)
{
    $arr = explode('|', trim($value));
    echo "Car: $arr[0], Price: $arr[1]<br>";
    
}
?>

Output:
Car: Volvo, Price: 100
Car: BMW, Price: 100
Car: Toyota, Price: 100
