PHP SQLite display records using parameters to Query

We will create the database and connection object.

$my_conn = new PDO('sqlite:my_student.sqlite3');

We will use $my_conn to execute our query.

By using WHERE condition we will display records of class 'Four'.

<?php 
   try {
     
    // Create (connect to) SQLite database in file
    $my_conn = new PDO('sqlite:my_student.sqlite3');
    // Set errormode to exceptions
    $my_conn->setAttribute(PDO::ATTR_ERRMODE, 
                            PDO::ERRMODE_EXCEPTION);
 
    // prepare Query 
    //  $sql="select *  from student";  // All students
	$sql="SELECT * FROM student WHERE class='Four'";
		
    echo "<table>";
	foreach ($my_conn->query($sql) as $row) {
		echo "<tr ><td>$row[id]</td><td>$row[name]</td></tr>";
	}
	echo "</table>";
	}
  catch(PDOException $e) 
  {
    // Print PDOException message
    echo $e->getMessage();
  }    
 $my_conn = null;
?>

In above code we have used foreach loop to get each row of records and displayed the same. We may have to collect the value of class from external source so it is better to use parameter query so we can Binds a parameter to a statement variable.

<?php 
    // Create (connect to) SQLite database in file
    $my_conn = new PDO('sqlite:my_student.sqlite3');
    // Set errormode to exceptions
    $my_conn->setAttribute(PDO::ATTR_ERRMODE, 
                            PDO::ERRMODE_EXCEPTION);
	$class='Four'; // Parameter, value  can be changed.
	$sql="SELECT * FROM student WHERE class=:class";
	$step = $my_conn->prepare($sql);
	$step->bindParam(':class', $class,PDO::PARAM_STR,10);
	$step->execute();
	$step = $step->fetchAll();
	echo "<table>";
	foreach ($step as $row) {
		echo "<tr ><td>$row[id]</td><td>$row[name]</td></tr>";
	}
	echo "</table>";
	

 $my_conn = null;
?>
