OR Code=?")) { $marker = $stmt->param_count; printf("Statement has %d markers.\n", $marker); /* close statement */ $stmt->close(); } /* close connection */ $mysqli->close(); ?>`

Exemplo 2. Procedural style
`<?php $link = mysqli_connect("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } if ($stmt = mysqli_prepare($link, "SELECT Name FROM Country WHERE Name=? OR Code=?")) { $marker = mysqli_stmt_param_count($stmt); printf("Statement has %d markers.\n", $marker); /* close statement */ mysqli_stmt_close($stmt); } /* close connection */ mysqli_close($link); ?>`
