How can indexing be utilized in PHP MySQL queries to enhance performance in database operations?

Indexing can be utilized in PHP MySQL queries to enhance performance in database operations by creating indexes on columns frequently used in WHERE clauses or JOIN conditions. This allows MySQL to quickly locate the rows that satisfy the query conditions, resulting in faster query execution. 

// Create an index on a column in a MySQL table
$query = "CREATE INDEX index_name ON table_name(column_name)";
$result = mysqli_query($connection, $query);

// Use the indexed column in a SELECT query
$query = "SELECT * FROM table_name WHERE indexed_column = 'value'";
$result = mysqli_query($connection, $query);
