mysqli_result->current_field -- mysqli_field_tell — Get current field offset of a result pointer
Object oriented style (property):
Procedural style:
Returns the position of the field cursor used for the last mysqli_fetch_field() call. This value can be used as an argument to mysqli_field_seek().
Nur bei prozeduralem Aufruf: Ein von mysqli_query(), mysqli_store_result() oder mysqli_use_result() zurückgegebenes Ergebnisobjekt.
Returns current offset of field cursor.
Beispiel #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 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 */
$mysqli->close();
?>
Beispiel #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, $query)) {
/* Get field information for all fields */
while ($finfo = mysqli_fetch_field($result)) {
/* get fieldpointer offset */
$currentfield = mysqli_field_tell($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", $finfo->type);
}
mysqli_free_result($result);
}
/* close connection */
mysqli_close($link);
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
Column 1: Name: Name Table: Country max. Len: 11 Flags: 1 Type: 254 Column 2: Name: SurfaceArea Table: Country max. Len: 10 Flags: 32769 Type: 4
