How can you check if a string is unserializeable in PHP?

To check if a string is unserializeable in PHP, you can use the `unserialize()` function and check if it returns `false`, which indicates that the string is not unserializeable. This can help prevent potential security vulnerabilities that may arise from attempting to unserialize malicious or corrupted data. 

$string = "a:1:{i:0;s:5:\"hello\";}"; // Example string to check
$unserialized_data = unserialize($string);

if ($unserialized_data === false) {
    echo "String is not unserializeable.";
} else {
    echo "String is unserializeable.";
}
