How can SQL statements with conditions be used effectively in PHP scripts?

To use SQL statements with conditions effectively in PHP scripts, you can dynamically construct your SQL query based on certain conditions using PHP variables. This allows you to customize your query and retrieve specific data from your database based on the conditions you set. 

// Example of using SQL statements with conditions in PHP script

// Set condition based on user input
$condition = "WHERE age > 18";

// Construct SQL query with condition
$sql = "SELECT * FROM users " . $condition;

// Execute the query and fetch results
$result = mysqli_query($connection, $sql);

// Loop through results
while($row = mysqli_fetch_assoc($result)) {
    // Process and display data
    echo $row['name'] . " - " . $row['age'] . "<br>";
}
