mysqli_result::field_seek -- mysqli_field_seek — Set result pointer to a specified field offset

### Description

Object oriented style

public mysqli_result::field_seek ( int `$fieldnr` ) : bool

Procedural style

mysqli_field_seek ( mysqli_result `$result` , int `$fieldnr` ) : bool

Sets the field cursor to the given offset. The next call to mysqli_fetch_field() will retrieve the field definition of the column associated with that offset.

> Note:

> To seek to the beginning of a row, pass an offset value of zero.

### Parameters

`result`

  Procedural style only: A result set identifier returned by mysqli_query(), mysqli_store_result() or mysqli_use_result().

`fieldnr`

  The field number. This value must be in the range from `0` to `number of fields - 1`.

### Return Values

Returns `TRUE` on success or `FALSE` on failure.

### Examples

Example #1 Object oriented style

`<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
$query = "SELECT Name, SurfaceArea from Country ORDER BY Code LIMIT 5";
if ($result = $mysqli->query($query)) {
/* Get field information for 2nd column */
$result->field_seek(1);
$finfo = $result->fetch_field();
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 */
$mysqli->close();
?>`

Example #2 Procedural style

`<?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
$query = "SELECT Name, SurfaceArea from Country ORDER BY Code LIMIT 5";
if ($result = mysqli_query($link, $query)) {
/* Get field information for 2nd column */
mysqli_field_seek($result, 1);
$finfo = mysqli_fetch_field($result);
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", $finfo->type);
mysqli_free_result($result);
}
/* close connection */
mysqli_close($link);
?>`

The above examples will output:

    Name:     SurfaceArea
    Table:    Country
    max. Len: 10
    Flags:    32769
    Type:     4
