浅析PHP数据导出知识点

<?php

$list = array (
  array('aaa', 'bbb', 'c', 'dddd'),
  array('123', '456', '789'),
  array('"aaa"', '"bbb"')
);

$fp = fopen('file.csv', 'w');

foreach ($list as $fields) {
  fputcsv($fp, $fields);
}

fclose($fp);
?>

<?php

$name = 'test';
header ( "Content-type:application/vnd.ms-excel" );
header ( "Content-Disposition:filename=".$name.".csv" );
header ('Cache-Control: max-age=0');

//打开PHP文件句柄，php://output 表示直接输出到浏览器
$fp = fopen('php://output', 'a');  

// 写入BOM头，防止乱码
fwrite($fp, chr(0xEF).chr(0xBB).chr(0xBF)); 

// 生成的测试数据
function test()
{
  for ($i=0; $i < 150000; $i++) {
    yield ['name', $i, '男'];
  }
}

// 表头
$headers = ['名字', '年龄', '性别'];

fputcsv($fp, $headers);

foreach (test() as $value) {
  fputcsv($fp, $value);
}

fclose($fp);
?>
