(PECL maxdb >= 1.0)

maxdb_field_tell -- maxdb_result::current_field — Get current field offset of a result pointer

### Description

Procedural style

int maxdb_field_tell ( resource `$result` )

Object oriented style

int $maxdb_result->current_field;

Returns the position of the field cursor used for the last maxdb_fetch_field() call. This value can be used as an argument to maxdb_field_seek().

### Return Values

Returns current offset of field cursor.

### 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();
}
$query = "SELECT name, cno from hotel.customer ORDER BY cno";
if ($result = $maxdb->query($query)) {
/* Get field information for all columns */
while ($finfo = $result->fetch_field()) {
/* get fieldpointer offset */
$currentfield = $result->current_field;
printf("Column %d:\n", $currentfield);
printf("Name: %s\n", $finfo->name);
printf("Table: %s\n", $finfo->table);
printf("max. Len: %d\n", $finfo->max_length);
printf("Flags: %d\n", $finfo->flags);
printf("Type: %d\n\n", $finfo->type);
}
$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();
}
$query = "SELECT name, cno from hotel.customer ORDER BY cno";
if ($result = maxdb_query($link, $query)) {
/* Get field information for all fields */
while ($finfo = maxdb_fetch_field($result)) {
/* get fieldpointer offset */
$currentfield = maxdb_field_tell($result);
printf("Column %d:\n", $currentfield);
printf("Name: %s\n", $finfo->name);
printf("Table: %s\n", $finfo->table);
printf("max. Len: %d\n", $finfo->max_length);
printf("Flags: %d\n", $finfo->flags);
printf("Type: %d\n\n", $finfo->type);
}
maxdb_free_result($result);
}
/* close connection */
maxdb_close($link);
?>`

The above example will output something similar to:

    Column    1:
    Name:     NAME
    Table:
    max. Len: 10
    Flags:    -1
    Type:     2

    Column    2:
    Name:     CNO
    Table:
    max. Len: 4
    Flags:    -1
    Type:     0
