try {
$pdo = new PDO ($DSN, $user, $pass); Initializes a PDO object, which is the creation of a database connection object $pdo
$query = "SELECT * from Tb_pdo_mysql"; Defining SQL statements
$result = $pdo->prepare ($query); Preparing query statements
$result->execute (); Executes a query statement and returns a result set
while ($res = $result->fetch (PDO::FETCH_ASSOC)) {//while loops out the query result set and sets the result set as the associated index
?>

<?php echo $res [' id '];? >
<?php echo $res [' Pdo_type '];? >
<?php echo $res [' database_name '];? >
<?php echo $res [' dates '];? >
) "> Delete

To delete a database record code:

$host = ' localhost '; Database host Name
$dbName = ' db_database19 '; The database used
$user = ' root '; Database connection user Name
$pass = ' root '; The corresponding password
$DSN = "$dbms: host= $host;d bname= $dbName";
try {
$pdo = new PDO ($DSN, $user, $pass); Initializes a PDO object, which is the creation of a database connection object $pdo
$pdo->setattribute (pdo::attr_errmode,pdo::errmode_exception);
$query = "Delete from tb_pdo_mysql where Id=:id";
$result = $pdo->prepare ($query); Pre-prepared statements
$result->bindparam (': Id ', $_get[' conn_id '); Binding the updated data
$result->execute ();
} catch (Pdoexception $e) {
Echo ' PDO Exception caught. ';
Echo ' Error with the database:
';
Echo ' SQL Query: '. $query;
Echo '

';
echo "Error:". $e->getmessage (). "
";
echo "Code:". $e->getcode (). "
";
echo "File:". $e->getfile (). "
";
echo "line:". $e->getline (). "
";
echo "Trace:". $e->gettraceasstring (). "
";
Echo '
