php 打包zip并下载（二进制流,不占用空间）

这里后端使用tp5 作为演示,话不多说直接上代码

1、创建zip工具类(网上找的实测好用)

<?php
namespace app\crm\traits;

class zipfile {
   
    var $datasec = array ();
    var $ctrl_dir = array ();
    var $eof_ctrl_dir = "\x50\x4b\x05\x06\x00\x00\x00\x00";
    var $old_offset = 0;

    function unix2_dostime($unixtime = 0){
   
        $timearray = ($unixtime == 0) ? getdate () : getdate($unixtime);
        if ($timearray ['year'] < 1980){
   
            $timearray ['year'] = 1980;
            $timearray ['mon'] = 1;
            $timearray ['mday'] = 1;
            $timearray ['hours'] = 0;
            $timearray ['minutes'] = 0;
            $timearray ['seconds'] = 0;
        }
        return (($timearray ['year'] - 1980) << 25) | ($timearray ['mon'] << 21) | ($timearray ['mday'] << 16) | ($timearray ['hours'] << 11) | ($timearray ['minutes'] << 5) | ($timearray ['seconds'] >> 1);
    }
    function add_file($data, $name, $time = 0){
   
        $name = str_replace('\\', '/', $name);

        $dtime = dechex($this->unix2_dostime($time));
        $hexdtime = '\x' . $dtime [6] . $dtime [7] . '\x' . $dtime [4] . $dtime [5] . '\x' . $dtime [2] . $dtime [3] . '\x' . $dtime [0] . $dtime [1];
        eval('$hexdtime = "' . $hexdtime . '";');

        $fr = "\x50\x4b\x03\x04";
        $fr .= "\x14\x00";
        $fr .= "\x00\x00";
        $fr .= "\x08\x00";
        $fr .= $hexdtime;

        $unc_len = strlen($data);
        $crc = crc32($data);
        $zdata = gzcompress($data);
        $zdata = substr(substr($zdata, 0, strlen($zdata)- 4), 2
