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, ....

Nota: 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.

Valori restituiti

Restituisce TRUE in caso di successo, FALSE in caso di fallimento.

Esempio 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();

?>

Esempio 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);
?>
