mysqli_stmt_bind_result

(PHP 5)

mysqli_stmt_bind_result

(no version information, might be only in CVS)

stmt->bind_result -- Binds variables to a prepared statement for result storage

Inhaltsverzeichnis

Description

Procedural style:

bool mysqli_stnt_bind_result ( object stmt, mixed var1 [, mixed var2, ...])
</BR >

Object oriented style (method):

class stmt {
</BR >bool bind_result ( mixed var1 [, mixed var2, ...])
</BR >}

mysqli_stmt_bind_result() is used to associate (bind) columns in the result set to variables. When function.mysqli-stmt-fetch is called to fetch data, the MySQL client/server protocol places the data for the bound columns into the specified variables var1, ....

Anmerkung: Note that all columns must be bound prior to calling function.mysqli-stmt-fetch. Depending on column types bound variables can silently change to the corresponding PHP type.

A column can be bound or rebound at any time, even after a result set has been partially retrieved. The new binding takes effect the next time function.mysqli-stmt-fetch is called.


Return values

Gibt bei Erfolg TRUE zurück, im Fehlerfall FALSE.

Example


Beispiel 1. Object oriented style

<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");

if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

/* prepare statement */
if ($stmt = $mysqli->prepare("SELECT Code, Name FROM Country ORDER BY Name LIMIT 5")) {
    $stmt->execute();

    /* bind variables to prepared statement */
    $stmt->bind_result($col1, $col2);

    /* fetch values */
    while ($stmt->fetch()) {
        printf("%s %s\n", $col1, $col2);
    }

    /* close statement */
    $stmt->close();
}
/* close connection */
$mysqli->close();

?>

Beispiel 2. Procedural style

<?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");

/* check connection */
if (!$link) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

/* prepare statement */
if ($stmt = mysqli_prepare($link, "SELECT Code, Name FROM Country ORDER BY Name LIMIT 5")) {
    mysqli_stmt_execute($stmt);

    /* bind variables to prepared statement */
    mysqli_stmt_bind_result($stmt, $col1, $col2);

    /* fetch values */
    while (mysqli_stmt_fetch($stmt)) {
       printf("%s %s\n", $col1, $col2);
    }

    /* close statement */
    mysqli_stmt_close($stmt);
}

/* close connection */
mysqli_close($link);
?>
