Eksempel #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();
}

$maxdb->query("CREATE TABLE temp.mycity LIKE hotel.city");

$city "'s Hertogenbosch";

/* this query will fail, cause we didn't escape $city */
if (!$maxdb->query("INSERT into temp.mycity VALUES ('11111','$city','NY')")) {
   
printf("Error: %s\n"$maxdb->sqlstate);
}

$city $maxdb->real_escape_string($city);

/* this query with escaped $city will work */
if ($maxdb->query("INSERT into temp.mycity VALUES ('22222','$city','NY')")) {
   
printf("%d Row inserted.\n"$maxdb->affected_rows);
}

$maxdb->close();
?>

Eksempel #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();
}

maxdb_query($link"CREATE TABLE temp.mycity LIKE hotel.city");

$city "'s Hertogenbosch";

/* this query will fail, cause we didn't escape $city */
if (!maxdb_query($link"INSERT into temp.mycity VALUES ('11111','$city','NY')")) {
   
printf("Error: %s\n"maxdb_sqlstate($link));
}

$city maxdb_real_escape_string($link$city);

/* this query with escaped $city will work */
if (maxdb_query($link"INSERT into temp.mycity VALUES ('22222','$city','NY')")) {
   
printf("%d Row inserted.\n"maxdb_affected_rows($link));
}

maxdb_close($link);
?>

The above example will output something similar to:

Warning: maxdb_query(): -5016 POS(43) Missing delimiter: ) <...>
Error: 42000
