$sql = 'SELECT * FROM Table WHERE Column = ?';
$stmt = $mysqli->stmt_init();
if ($stmt->prepare($sql)) {
$stmt->bind_param('s', $ColumnValue);
$stmt->execute();
$stmt->bind_result($Col1, $Col2);
$stmt->fetch();
$stmt->close();
}
// or
if ($stmt = $mysqli->prepare($sql)) {
$stmt->bind_param('s', $ColumnValue);
$stmt->execute();
$stmt->bind_result($Col1, $Col2);
$stmt->fetch();
$stmt->close();
}
在处理准备好的陈述时,区别是什么?哪个应该用?
