csv表格的一种，so ，看需求吧，有的需求指定用csv ```php $csv = ""; foreach ($data as $row) { //把数组元素组合为一个字符串： join() 函数是 implode() 函数的别名。 $csv .= join(",", $row) . "n"; } echo $csv; <?php function toCSV(array $data, array $colHeaders = array(), $asString = false) { $stream = ($asString) ? fopen("php://temp/maxmemory", "w+") : fopen("php://output", "w"); //头部 if (!empty($colHeaders)) { fputcsv($stream, $colHeaders); } //数据 foreach ($data as $record) { fputcsv($stream, $record); } //作为字符串 if ($asString) { rewind($stream); $returnVal = stream_get_contents($stream); fclose($stream); return $returnVal; } else { fclose($stream); } } ```
