How can PHP developers avoid using the LIKE operator in SQL queries to improve performance?

Using the LIKE operator in SQL queries can lead to performance issues, especially when dealing with large datasets. One way to avoid using LIKE is to use full-text search indexes or implement filtering on the PHP side before querying the database. 

// Example of implementing filtering on the PHP side before querying the database
$searchTerm = 'example';
$filteredSearchTerm = '%' . $searchTerm . '%'; // Add wildcards to mimic LIKE behavior

// Perform additional validation or sanitization on $filteredSearchTerm if needed

// Execute SQL query with the filtered search term
$query = "SELECT * FROM table WHERE column LIKE :searchTerm";
$stmt = $pdo->prepare($query);
$stmt->bindParam(':searchTerm', $filteredSearchTerm);
$stmt->execute();
$results = $stmt->fetchAll();
