stmt->send_long_data() — Send data in blocks

说明

Procedural style:

bool mysqli_stmt_send_long_data ( mysqli_stmt $stmt , int $param_nr , string $data )

Object oriented style (method)

mysqli_stmt

bool send_long_data ( int $param_nr , string $data )

Allows to send parameter data to the server in pieces (or chunks), e.g. if the size of a blob exceeds the size of max_allowed_packet. This function can be called multiple times to send the parts of a character or binary data value for a column, which must be one of the TEXT or BLOB datatypes.

参数

stmt: Procedural style only: A statement identifier returned by mysqli_stmt_init().
param_nr: Indicates which parameter to associate the data with. Parameters are numbered beginning with 0.
data: A string containing data to be sent.

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
$stmt = $mysqli->prepare("INSERT INTO messages (message) VALUES (?)");
$null = NULL;
$stmt->bind_param("b", $null);
$fp = fopen("messages.txt", "r");
while (!feof($fp)) {
    $stmt->send_long_data(0, fread($fp, 8192));
}
fclose($fp);
$stmt->execute();
?>
