How can one efficiently search and retrieve data from a database in PHP for content matching a specific query?

To efficiently search and retrieve data from a database in PHP for content matching a specific query, you can use SQL SELECT statements with prepared statements to prevent SQL injection attacks. You can also use LIKE or full-text search queries to search for partial matches or specific keywords in the database. 

<?php
// Establish a connection to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Prepare a SQL query to search for content matching a specific query
$search_query = "SELECT * FROM table_name WHERE column_name LIKE ?";
$stmt = $conn->prepare($search_query);

// Bind the parameter and execute the query
$search_term = "%specific_query%";
$stmt->bind_param("s", $search_term);
$stmt->execute();

// Retrieve the results
$result = $stmt->get_result();

// Loop through the results and output the data
while ($row = $result->fetch_assoc()) {
    echo "Column Name: " . $row['column_name'] . "<br>";
}

// Close the connection
$stmt->close();
$conn->close();
?>
