What are the advantages and disadvantages of using MySQL functions versus PHP functions for database searches?

When performing database searches, using MySQL functions can be more efficient as the queries are executed directly on the database server. On the other hand, using PHP functions for database searches can provide more flexibility and control over the data manipulation process. It is important to consider the specific requirements of the project and choose the appropriate approach based on performance and functionality needs.

// Using MySQL functions for database search
$query = "SELECT * FROM table_name WHERE column_name = 'search_term'";
$result = mysqli_query($connection, $query);

// Using PHP functions for database search
$query = "SELECT * FROM table_name";
$result = mysqli_query($connection, $query);

while ($row = mysqli_fetch_assoc($result)) {
    if ($row['column_name'] == 'search_term') {
        // Perform desired action
    }
}
