How can PHP be used to output matching entries from a MySQL database based on user input?

To output matching entries from a MySQL database based on user input, you can use PHP to create a query that searches for the input in the database and then display the results. You can use the $_POST or $_GET superglobals to capture user input and then use that input in a SQL query to fetch the matching records from the database. 

<?php
// Assuming you have already established a connection to your MySQL database

if(isset($_POST['search'])) {
    $search = $_POST['search'];
    
    $query = "SELECT * FROM your_table_name WHERE column_name LIKE '%$search%'";
    $result = mysqli_query($connection, $query);

    while($row = mysqli_fetch_assoc($result)) {
        echo $row['column_name_to_display'];
    }
}
?>

<form method="post" action="">
    <input type="text" name="search" placeholder="Search">
    <button type="submit">Search</button>
</form>
