Examples

Example 1240. 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();
?>


Example 1241. 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 examples would produce the following output:

Error: 42000
1 Row inserted.
