How can dynamic values be called under MySQL in PHP?

Dynamic values in MySQL can be called in PHP by executing SQL queries using PHP's built-in functions like mysqli_query or PDO. These functions allow you to pass dynamic values as parameters in the query to prevent SQL injection attacks. By using prepared statements, you can safely execute queries with dynamic values in MySQL from PHP. 

// Example of calling dynamic values under MySQL in PHP using PDO

// Establish a connection to the database
$pdo = new PDO('mysql:host=localhost;dbname=my_database', 'username', 'password');

// Prepare a SQL query with a placeholder for the dynamic value
$stmt = $pdo->prepare("SELECT * FROM my_table WHERE column_name = :dynamic_value");

// Bind the dynamic value to the placeholder
$dynamic_value = 'some_value';
$stmt->bindParam(':dynamic_value', $dynamic_value);

// Execute the query
$stmt->execute();

// Fetch the results
$results = $stmt->fetchAll();

// Loop through the results
foreach ($results as $row) {
    // Do something with the data
}
