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

Описание

Procedural style:

bool mysqli_stmt_bind_result ( mysqli_stmt $stmt , mixed &$var1 [, mixed &$... ] )

Object oriented style (method):

mysqli_stmt
bool bind_result ( mixed &$var1 [, mixed &$... ] )

Binds columns in the result set to variables.

When 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, ... .

Note: Note that all columns must be bound after mysqli_stmt_execute() and prior to calling 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 mysqli_stmt_fetch() is called.

Список параметров

stmt

Procedural style only: A statement identifier returned by mysqli_stmt_init().

var1

The variable to be bound.

Возвращаемые значения

Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.

Примеры

Example#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();

?>

Example#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);
?>
