# maxdb_fetch_lengths

# result->lengths

(No version information available, might be only in CVS)

result->lengths — Returns the lengths of the columns of the current row in the result set

### Description

Procedural style:

array maxdb_fetch_lengths ( resource `$result` )

Object oriented style (property):

result
array$lengths;

The maxdb_fetch_lengths() function returns an array containing the lengths of every column of the current row within the result set represented 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() 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\n", 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\n", $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\n", 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\n", $i+1, $val);
}
maxdb_free_result($result);
}
/* close connection */
maxdb_close($link);
?>`

The above examples would produce the following output:

    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
