下载一个zip文件 怎么用php实现

wnload.php 文件部分, 根据自己的需要修改一下 //---------------------- 中间的部分即可

?php

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 = gz......一帆风顺吉星到 万事如意福临门 财源广进

使用方式如下：

<?php

$zip = new ZipArchive()

$filename = "./test112.zip"

if ($zip->open($filename, ZIPARCHIVE::CREATE)!==TRUE) {

exit("cannot open <$filename>")

}

$zip->addFromString("testfilephp.txt" . time(), "#1 This is a test string added as testfilephp.txt. ")

$zip->addFromString("testfilephp2.txt" . time(), "#2 This is a test string added as testfilephp2.txt. ")

$zip->addFile($thisdir . "/too.php","/testfromfile.php")

echo "numfiles: " . $zip->numFiles . " "

echo "status:" . $zip->status . " "

$zip->close()

?>
