SYNOPSIS
array maxdb_fetch_lengths (resource $result)
DESCRIPTION
Object oriented style
array$maxdb_result->lengths ()
The maxdb_fetch_lengths(3) function returns an array containing the lengths of every column of the current row within the result set rep-
resented by the $result parameter. If successful, a numerically indexed array representing the lengths of each column is returned or FALSE
on failure.
RETURN VALUES
An array of integers representing the size of each column (not including any terminating null characters). FALSE if an error occurred.
maxdb_fetch_lengths(3) is valid only for the current row of the result set. It returns FALSE if you call it before calling
maxdb_fetch_row/array/resource or after retrieving all rows in the result.
EXAMPLES
Example #1
Object oriented style
<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s
", maxdb_connect_error());
exit();
}
$query = "SELECT * from hotel.customer WHERE cno = 3000";
if ($result = $maxdb->query($query)) {
$row = $result->fetch_row();
/* display column lengths */
foreach ($result->lengths as $i => $val) {
printf("Field %2d has Length %2d
", $i+1, $val);
}
$result->close();
}
/* close connection */
$maxdb->close();
?>
Example #2
Procedural style
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s
", maxdb_connect_error());
exit();
}
$query = "SELECT * from hotel.customer WHERE cno = 3000";
if ($result = maxdb_query($link, $query)) {
$row = maxdb_fetch_row($result);
/* display column lengths */
foreach (maxdb_fetch_lengths($result) as $i => $val) {
printf("Field %2d has Length %2d
", $i+1, $val);
}
maxdb_free_result($result);
}
/* close connection */
maxdb_close($link);
?>
The above example will output something similar to:
Field 1 has Length 4
Field 2 has Length 3
Field 3 has Length 5
Field 4 has Length 6
Field 5 has Length 5
Field 6 has Length 21
