# maxdb_fetch_lengths

(no version information, might be only in CVS)

maxdb_fetch_lengths -- Returns the lengths of the columns of the current row in the result set

## Description

Procedural style:

mixed maxdb_fetch_lengths ( resource result )

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.

## Example

Exemplo 1. Procedural style
`<?php $link = maxdb_connect("localhost", "MONA", "RED"); /* 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 */ $lengths = maxdb_fetch_lengths($result); for ($i=0; $i < count($lengths); $i++) { printf("Field %2d has Length %2d\n", $i+1, $lengths[$i]); } 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
