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 DescriptionProcedural 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, ....
注:
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.
返回值
如果成功则返回 TRUE，失败则返回 FALSE。
例例子 1. Object oriented style |
<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
if ($stmt = $mysqli->prepare("SELECT Code, Name FROM Country ORDER BY Name LIMIT 5")) {
$stmt->execute();
$stmt->bind_result($col1, $col2);
while ($stmt->fetch()) {
printf("%s %s\n", $col1, $col2);
}
$stmt->close();
}
$mysqli->close();
?>

例子 2. Procedural style |
<?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
if (!$link) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
if ($stmt = mysqli_prepare($link, "SELECT Code, Name FROM Country ORDER BY Name LIMIT 5")) {
mysqli_stmt_execute($stmt);
mysqli_stmt_bind_result($stmt, $col1, $col2);
while (mysqli_stmt_fetch($stmt)) {
printf("%s %s\n", $col1, $col2);
}
mysqli_stmt_close($stmt);
}
mysqli_close($link);
?>
