Beschreibung
Procedural style:
Object oriented style (property)
The maxdb_error() function is identical to the corresponding maxdb_errno() function in every way, except instead of returning an integer error code the maxdb_error() function will return a string representation of the last error to occur for the database connection represented by the link parameter. If no error has occured, this function will return an empty string.
Rückgabewerte
A string that describes the error. An empty string if no error occurred.

Beispiel #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 (!
$maxdb->query("SELECT xxx FROM hotel.city")) {
printf("Errormessage: %s\n", $maxdb->error);
}/* close connection */
$maxdb->close();
?>Beispiel #2 Procedural style
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}if (!
maxdb_query($link, "SELECT xxx FROM hotel.city")) {
printf("Errormessgae: %s\n", maxdb_error($link));
}/* close connection */
maxdb_close($link);
