How can the error "Uncaught TypeError: Unsupported operand types: string * int" in PHP be resolved?

The error "Uncaught TypeError: Unsupported operand types: string * int" occurs when trying to perform a multiplication operation between a string and an integer in PHP. To resolve this issue, you need to ensure that both operands are of the same data type before performing the multiplication operation. You can achieve this by explicitly converting the string to an integer using the `intval()` function. 

$string = "10";
$int = 5;

// Convert the string to an integer before performing the multiplication
$result = intval($string) * $int;

echo $result; // Output: 50
