How can indexing be utilized to improve the speed of MySQL queries in PHP?

Indexing can be utilized to improve the speed of MySQL queries in PHP by creating indexes on columns frequently used in WHERE clauses or JOIN conditions. This allows MySQL to quickly locate the rows that match the conditions specified in the query, resulting in faster query execution. 

// Example code snippet demonstrating how to create an index on a column in MySQL using PHP

// Connect to MySQL database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Create an index on the 'email' column in the 'users' table
$index_query = "CREATE INDEX email_index ON users(email)";
$mysqli->query($index_query);

// Run your MySQL query with the indexed column
$query = "SELECT * FROM users WHERE email = 'example@email.com'";
$result = $mysqli->query($query);

// Process the query result
while ($row = $result->fetch_assoc()) {
    // Do something with the data
}

// Close the database connection
$mysqli->close();
