How can you perform a SELECT query in PHP to search for data based on a partial match in a cell?

When performing a SELECT query in PHP to search for data based on a partial match in a cell, you can use the LIKE operator in your SQL query. The LIKE operator allows you to search for a specified pattern in a column. To search for a partial match, you can use the % wildcard character before, after, or both before and after the search term. 

<?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);
}

// Search for data based on a partial match in a cell
$search_term = "partial_match";
$sql = "SELECT * FROM table_name WHERE column_name LIKE '%$search_term%'";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Column value: " . $row["column_name"] . "<br>";
    }
} else {
    echo "0 results found";
}

$conn->close();
?>
