1. 设置数据

$data = [
    [
        ‘xubin,123321‘,
        ‘feifei,332234‘,
        ‘tengfei‘,
        ‘323423434343324323423432423432434324234324324324332‘
    ],
    [
        ‘xubi123n‘,
        ‘feife321i‘,
        ‘ten321gfei‘
    ]
];

2. 处理数据

foreach ($data as $k => $vs) {
    foreach ($vs as $vk => $v) {
        //如果是数字则增加制表符 防止科学计数法
        if (is_numeric($v)) {
            $v = "\t" . $v;
        }
        //去除字符中的,号
        $v = str_replace(‘,‘, ‘，‘, $v);
        //转义防止乱码
        $v = iconv(‘utf-8‘, ‘gbk//TRANSLIT//IGNORE‘, $v);

        $vs[$vk] = $v;
    }
    $data[$k] = implode(‘,‘, $vs);
}

3. 生成csv文件

$data = implode("\n", $data);
//保存数据
$name = uniqid() . ‘.csv‘;
file_put_contents($path . ‘/‘ . $name, $data);
$url = request()->domain() . ‘/cache/excel/‘ . $name;
$url = str_replace(‘\\‘, ‘/‘, $url);

php 使用file_put_content将 数据 push 到csv文件中
