## Example

Példa 1. Object oriented style
`<?php $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s\n", maxdb_connect_error()); exit(); } if ($stmt = $maxdb->prepare("SELECT name FROM hotel.city WHERE name=? OR state=?")) { $marker = $stmt->param_count; printf("Statement has %d markers.\n", $marker); /* close statement */ $stmt->close(); } /* close connection */ $maxdb->close(); ?>`

Példa 2. Procedural style
`<?php $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s\n", maxdb_connect_error()); exit(); } if ($stmt = maxdb_prepare($link, "SELECT name FROM hotel.city WHERE name=? OR state=?")) { $marker = maxdb_stmt_param_count($stmt); printf("Statement has %d markers.\n", $marker); /* close statement */ maxdb_stmt_close($stmt); } /* close connection */ maxdb_close($link); ?>`

The above examples would produce the following output:

    Statement has 2 markers.
