# 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

## Description

Procedural style:

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

Object oriented style (method):

class mysqli_stmt {
bool bind_result ( mixed &var1 [, mixed &...] )
}

mysqli_stmt_bind_result() is used to associate (bind) 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, ....

> Megjegyzés: Note that all columns must be bound 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.

## Visszatérési értékek

## Példák

Példa 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(); ?>`

Példa 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); ?>`
