How important is it for PHP developers to familiarize themselves with the LIKE operator and wildcard characters when working with MySQL databases?

It is essential for PHP developers to familiarize themselves with the LIKE operator and wildcard characters when working with MySQL databases as they allow for more flexible and powerful search queries. The LIKE operator is used to search for a specified pattern in a column, while wildcard characters such as '%' and '_' can be used to represent any sequence of characters or a single character, respectively. Understanding how to use these tools effectively can greatly improve the efficiency and accuracy of database queries. 

$search_term = "example";
$query = "SELECT * FROM table_name WHERE column_name LIKE '%$search_term%'";
// Execute the query and fetch results
