mysqli_stmt::send_long_data -- mysqli_stmt_send_long_data — Send data in blocks
Object oriented style (method)
Procedural style:
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.
Procedural style only: A statement identifier returned by mysqli_stmt_init().
Indicates which parameter to associate the data with. Parameters are numbered beginning with 0.
A string containing data to be sent.
如果成功则返回 TRUE，失败则返回 FALSE。
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();
?>
