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

### Description

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.

### Parameters

`stmt`

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

`var1`

  The variable to be bound.

### Return Values

Returns `TRUE` on success or `FALSE` on failure.

### Examples

Example#1 Object oriented style

`<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
/* prepare statement */
if ($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);
?>`

The above example will output:

    AFG Afghanistan
    ALB Albania
    DZA Algeria
    ASM American Samoa
    AND Andorra
