To get a column with duplicate records using PHP and MySQL, you can use the following steps:

  1. Connect to the MySQL database: $conn = mysqli_connect("localhost", "username", "password", "database");
  2. Execute a MySQL query to select the column with duplicate records. In this example, we assume the table name is "your_table" and the column name is "your_column": $sql = "SELECT your_column FROM your_table GROUP BY your_column HAVING COUNT(*) > 1"; $result = mysqli_query($conn, $sql);
  3. Iterate through the result set and print the duplicate column values: if (mysqli_num_rows($result) > 0) { while ($row = mysqli_fetch_assoc($result)) { echo $row['your_column'] . ""; } } else { echo "No duplicate records found."; }
  4. Close the database connection: mysqli_close($conn);


Make sure to replace "localhost", "username", "password", "database", "your_table", and "your_column" with the appropriate values for your database setup.
