# mysqli_bind_result

(PHP 5 CVS only)

mysqli_bind_result

(no version information, might be only in CVS)

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

## Description

Procedural style:

bool mysqli_bind_result ( object stmt, mixed var1 [, mixed var2, ...])

Object oriented style (method):

class stmt {
bool bind_result ( mixed var1 [, mixed var2, ...])
}

mysqli_bind_result() is used to associate (bind) columns in the result set to variables. When mysqli_fetch() is called to fetch data, the MySQL client/server protocol places the data for the bound columns into the specified variables `var1, ...`.

> Notatka: Note that all columns must be bound prior to calling mysqli_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_fetch() is called.

## Return values

Zwraca `TRUE` w przypadku sukcesu, `FALSE` w przypadku porażki.

## Example

Przykład 1. Object oriented style
`<?php $mysqli = new mysqli("localhost", "my_user", "my_password", "test"); if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } /* create table and insert some data */ $mysqli->query("DROP TABLE IF EXISTS bind_result"); $mysqli->query("CREATE TABLE bind_result (id int, extension varchar(20))"); $mysqli->query("INSERT INTO bind_result VALUES (1, 'ldap')"); $mysqli->query("INSERT INTO bind_result VALUES (2, 'mysql')"); $mysqli->query("INSERT INTO bind_result VALUES (3, 'pcre')"); /* prepare statement */ if ($stmt = $mysqli->prepare("SELECT id, extension FROM bind_result")) { $stmt->execute(); /* bind variables to prepared statement */ $stmt->bind_result($col1, $col2); /* fetch values */ while ($stmt->fetch()) { printf("Id: %d Extension: %s\n", $col1, $col2); } /* close statement */ $stmt->close(); } /* close connection */ $mysqli->close(); ?>`

Przykład 2. Procedural style
`<?php $link = mysqli_connect("localhost", "my_user", "my_password", "test") or die("Can't connect to MySQL server on localhost"); /* create table and insert some data */ mysqli_query($link, "DROP TABLE IF EXISTS bind_result"); mysqli_query($link, "CREATE TABLE bind_result (id int, extension varchar(20))"); mysqli_query($link, "INSERT INTO bind_result VALUES (1, 'ldap')"); mysqli_query($link, "INSERT INTO bind_result VALUES (2, 'mysql')"); mysqli_query($link, "INSERT INTO bind_result VALUES (3, 'pcre')"); /* prepare statement */ if ($stmt = mysqli_prepare($link, "SELECT id, extension FROM bind_result")) { mysqli_execute($stmt); /* bind variables to prepared statement */ mysqli_bind_result($stmt, $col1, $col2); /* fetch values */ while (mysqli_fetch($stmt)) { printf("Id: %d Extension: %s\n", $col1, $col2); } /* close statement */ mysqli_stmt_close($stmt); } /* close connection */ mysqli_close($link); ?>`
