(PHP 5, PHP 7, PHP 8)

mysqli_stmt::bind_result -- mysqli_stmt_bind_result — Binds variables to a prepared statement for result storage

### Description

Object-oriented style

public mysqli_stmt::bind_result(mixed `&$var`, mixed `&...$vars`): bool

Procedural style

mysqli_stmt_bind_result(mysqli_stmt `$statement`, mixed `&$var`, mixed `&...$vars`): bool

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 `var`/`vars`.

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.

> Note:

> All columns must be bound after mysqli_stmt_execute() and prior to calling mysqli_stmt_fetch().

> Note:

> Depending on column types bound variables can silently change to the corresponding PHP type.

Tip

This function is useful for simple results. To retrieve iterable result set, or fetch each row as an array or object, use mysqli_stmt_get_result().

### Parameters

`statement`

  Procedural style only: A mysqli_stmt object returned by mysqli_stmt_init().

`var`

  The first variable to be bound.

`vars`

  Further variables to be bound.

### Return Values

Returns `true` on success or `false` on failure.

### Examples

Example #1 Object-oriented style

`<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
/* prepare statement */
$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);
}`

Example #2 Procedural style

`<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
/* prepare statement */
$stmt = mysqli_prepare($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);
}`

The above examples will output something similar to:

    AFG Afghanistan
    ALB Albania
    DZA Algeria
    ASM American Samoa
    AND Andorra
