Object oriented style
SYNOPSIS
bool mysqli_result::field_seek (int $fieldnr)
DESCRIPTION
Procedural style
bool mysqli_field_seek (mysqli_result $result, int $fieldnr)
Sets the field cursor to the given offset. The next call to mysqli_fetch_field(3) will retrieve the field definition of the column associ-
ated with that offset.
Note
To seek to the beginning of a row, pass an offset value of zero.
PARAMETERS
o $
result -Procedural style only: A result set identifier returned by mysqli_query(3), mysqli_store_result(3) or
mysqli_use_result(3).
o $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
", 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
", $finfo->name);
printf("Table: %s
", $finfo->table);
printf("max. Len: %d
", $finfo->max_length);
printf("Flags: %d
", $finfo->flags);
printf("Type: %d
", $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
", 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
", $finfo->name);
printf("Table: %s
", $finfo->table);
printf("max. Len: %d
", $finfo->max_length);
printf("Flags: %d
", $finfo->flags);
printf("Type: %d
", $finfo->type);
mysqli_free_result($result);
}
/* close connection */
mysqli_close($link);
?>
The above examples will output:
Name: SurfaceArea
Table: Country
max. Len: 10
Flags: 32769
Type: 4
