## Example

Exemplo 1. Object oriented style
`<?php $mysqli = new mysqli("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } $mysqli->query("CREATE TABLE myCity LIKE City"); /* a remarkable city in Wales */ $query = "INSERT INTO myCity (CountryCode, Name) VALUES('GBR', 'Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch')"; $mysqli->query($query); if ($mysqli->warning_count) { if ($result = $mysqli->query("SHOW WARNINGS")) { $row = $result->fetch_row(); printf("%s (%d): %s\n", $row[0], $row[1], $row[2]); $result->close(); } } /* close connection */ $mysqli->close(); ?>`

Exemplo 2. Procedural style
`<?php $link = mysqli_connect("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } mysqli_query($link, "CREATE TABLE myCity LIKE City"); /* a remarkable long city name in Wales */ $query = "INSERT INTO myCity (CountryCode, Name) VALUES('GBR', 'Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch')"; mysqli_query($link, $query); if (mysqli_warning_count($link)) { if ($result = mysqli_query($link, "SHOW WARNINGS")) { $row = mysqli_fetch_row($result); printf("%s (%d): %s\n", $row[0], $row[1], $row[2]); mysqli_free_result($result); } } /* close connection */ mysqli_close($link); ?>`

The above examples would produce the following output:

    Warning (1264): Data truncated for column 'Name' at row 1
