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

说明

Procedural style:

bool maxdb_stmt_bind_result ( resource $stmt , mixed &$var1 [, mixed &$... ] )

Object oriented style (method):

stmt

bool bind_result ( mixed &$var1 [, mixed &$... ] )

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

Note: Note that all columns must be bound prior to calling maxdb_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 maxdb_stmt_fetch() is called.

返回值

如果成功则返回 TRUE，失败则返回 FALSE。

范例

Example#1 Object oriented style


<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");

if (maxdb_connect_errno()) {
   printf("Connect failed: %s\n", maxdb_connect_error());
   exit();
}

/* prepare statement */
if ($stmt = $maxdb->prepare("SELECT zip, name FROM hotel.city ORDER BY name")) {
   $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 */
$maxdb->close();

?>

Example#2 Procedural style


<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");

/* check connection */
if (!$link) {
   printf("Connect failed: %s\n", maxdb_connect_error());
   exit();
}

/* prepare statement */
if ($stmt = maxdb_prepare($link, "SELECT zip, name FROM hotel.city ORDER BY name")) {
   maxdb_stmt_execute($stmt);

   /* bind variables to prepared statement */
   maxdb_stmt_bind_result($stmt, $col1, $col2);

   /* fetch values */
   while (maxdb_stmt_fetch($stmt)) {
       printf("%s %s\n", $col1, $col2);
   }

   /* close statement */
   maxdb_stmt_close($stmt);
}

/* close connection */
maxdb_close($link);
?>
