mysqli_stmt::fetch -- mysqli_stmt_fetch — Fetch results from a prepared statement into the bound variables

### Beschreibung

Objektorientierter Stil

bool mysqli_stmt::fetch ( void )

Prozeduraler Stil

bool mysqli_stmt_fetch ( mysqli_stmt `$stmt` )

Fetch the result from a prepared statement into the variables bound by mysqli_stmt_bind_result().

> Hinweis:

> Note that all columns must be bound by the application before calling mysqli_stmt_fetch().

> Hinweis:

> Data are transferred unbuffered without calling mysqli_stmt_store_result() which can decrease performance (but reduces memory cost).

### Parameter-Liste

`stmt`

  Nur bei prozeduralem Aufruf: ein von mysqli_stmt_init() zurückgegebenes Statementobjekt.

### Rückgabewerte

Rückgabewerte
Value | Description
--- | ---
`TRUE` | Success. Data has been fetched
`FALSE` | Error occurred
`NULL` | No more rows/data exists or data truncation occurred

### Beispiele

Beispiel #1 Objektorientierter Stil

`<?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();
}
$query = "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 150,5";
if ($stmt = $mysqli->prepare($query)) {
/* execute statement */
$stmt->execute();
/* bind result variables */
$stmt->bind_result($name, $code);
/* fetch values */
while ($stmt->fetch()) {
printf ("%s (%s)\n", $name, $code);
}
/* close statement */
$stmt->close();
}
/* close connection */
$mysqli->close();
?>`

Beispiel #2 Prozeduraler Stil

`<?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();
}
$query = "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 150,5";
if ($stmt = mysqli_prepare($link, $query)) {
/* execute statement */
mysqli_stmt_execute($stmt);
/* bind result variables */
mysqli_stmt_bind_result($stmt, $name, $code);
/* fetch values */
while (mysqli_stmt_fetch($stmt)) {
printf ("%s (%s)\n", $name, $code);
}
/* close statement */
mysqli_stmt_close($stmt);
}
/* close connection */
mysqli_close($link);
?>`
