Examples

Example 1228. 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 (
$result = $maxdb->query("SELECT * FROM hotel.city ORDER BY zip")) {

 
/* determine number of fields in result set */
 
$field_cnt = $result->field_count;

 
printf("Result set has %d fields.\n", $field_cnt);

 
/* close result set */
 
$result->close();
}

/* close connection */
$maxdb->close();
?>


Example 1229. 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 (
$result = maxdb_query($link, "SELECT * FROM hotel.city ORDER BY zip")) {

 
/* determine number of fields in result set */
 
$field_cnt = maxdb_num_fields($result);

 
printf("Result set has %d fields.\n", $field_cnt);

 
/* close result set */
 
maxdb_free_result($result);
}

/* close connection */
maxdb_close($link);
?>


The above examples would produce the following output:

Result set has 3 fields.
