PHP（Thinkphp框架）将数据表导出csv文件

CSV文件类似于excel文件，用逗号表示分隔符,换行符代表该行结束

访问方法

public function export_csv()
{
$csvModel = M('select_question');
$csvData = $csvModel->field('question,answer_A,answer_B,answer_C,answer_D,true_answer')->select();
$str = "题目,答案A,答案B,答案C,答案D,正确答案\n";
$str = iconv('utf-8', 'gb2312', $str);
foreach ($csvData as $item) {
$question = iconv('utf-8', 'gb2312', $item['question']);
$a = iconv('utf-8', 'gb2312', $item['answer_a']);
$b = iconv('utf-8', 'gb2312', $item['answer_b']);
$c = iconv('utf-8', 'gb2312', $item['answer_c']);
$d = iconv('utf-8', 'gb2312', $item['answer_d']);
$t = iconv('utf-8', 'gb2312', $item['true_answer']);
$str .= $question . "," . $a . "," . $b . "," . $c . "," . $d . "," . $t . "\n";
}
$filename = '选择题.csv';
$this->export_filename($filename, $str);
}
