How can PHP developers efficiently search for a specific string within another string in MySQL queries, and what functions or methods can be used for this purpose?

To efficiently search for a specific string within another string in MySQL queries, PHP developers can use the MySQL `LIKE` operator in their queries. This operator allows for pattern matching within string columns. Additionally, PHP developers can use the `strpos()` function to search for a specific substring within a string in PHP. 

$search_string = "specific_string";
$query = "SELECT * FROM table_name WHERE column_name LIKE '%".$search_string."%'";
$result = mysqli_query($connection, $query);

if($result) {
    while($row = mysqli_fetch_assoc($result)) {
        // Process the results
    }
} else {
    echo "Error executing query: " . mysqli_error($connection);
}
