How can PHP be used to query timestamps in a database for specific time ranges?

When querying timestamps in a database for specific time ranges, you can use SQL queries with PHP to fetch the desired data. You can specify the time range using SQL's `BETWEEN` clause or comparison operators like `>=` and `<=`. Make sure to properly format the timestamps in your PHP code before passing them to the SQL query to avoid any syntax errors. 

// Connect to the database
$servername = &quot;localhost&quot;;
$username = &quot;username&quot;;
$password = &quot;password&quot;;
$dbname = &quot;database&quot;;

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

// Define the time range
$start_time = &quot;2022-01-01 00:00:00&quot;;
$end_time = &quot;2022-01-31 23:59:59&quot;;

// Query to fetch timestamps within the specified time range
$sql = &quot;SELECT * FROM table_name WHERE timestamp_column BETWEEN &#039;$start_time&#039; AND &#039;$end_time&#039;&quot;;

$result = $conn-&gt;query($sql);

// Process the query results
if ($result-&gt;num_rows &gt; 0) {
    while($row = $result-&gt;fetch_assoc()) {
        // Process the data
    }
} else {
    echo &quot;No results found.&quot;;
}

// Close the database connection
$conn-&gt;close();
