In what ways can the use of LIKE versus the equality operator in SQL queries impact the results and performance of a PHP application?

Using the LIKE operator in SQL queries can impact the results and performance of a PHP application because it allows for pattern matching, which can be less efficient than using the equality operator for exact matches. To improve performance, it is recommended to use the equality operator when searching for exact matches in SQL queries. 

// Using the equality operator in SQL query for exact match
$query = "SELECT * FROM table_name WHERE column_name = :value";
$stmt = $pdo->prepare($query);
$stmt->bindParam(':value', $search_value);
$stmt->execute();
$results = $stmt->fetchAll();
