How can a PHP server know in which table column to insert data?

To insert data into a specific table column, the PHP server needs to include the column name in the SQL query along with the values to be inserted. This can be achieved by constructing the SQL query dynamically based on the column name provided by the user or determined by the application logic. 

<?php
// Assume $columnName and $columnValue are provided or determined dynamically
$columnName = 'column_name';
$columnValue = 'column_value';

// Connect to the database
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

// Prepare the SQL query with placeholders for column name and value
$sql = "INSERT INTO mytable ($columnName) VALUES (:value)";

// Prepare and execute the query with the column value bound to the placeholder
$stmt = $pdo->prepare($sql);
$stmt->bindParam(':value', $columnValue);
$stmt->execute();
?>
