php要實現壓縮功能,除了透過安裝perl外掛到server上之外，另一種簡單的方式就是透過include php的class,以下為下載連結
下載pclzip: http://www.phpconcept.net/pclzip/pclzip-downloads
下載後放置到您的php網站底下,然後透過include的方式把該class引用進php文件
include("pclzip.lib.php");
zip壓縮後下載到client端
$val = '要壓縮的文件名稱或資料夾名稱';
$zipDir_ignore = dirname(__FILE__)."/"; //忽略掉前面的資料夾結構
$zipDir = dirname(__FILE__)."/" .$val."/"; //建立來源資料夾結構
$filepath = dirname(__FILE__)."/" .$val."/"; //建立zip檔目的地
$filename = $val.".zip"; //建立zip檔檔名
//開始進行壓縮
$archive = new PclZip($filepath.$filename);
$v_dir = $zipDir;
$v_remove = $zipDir_ignore;
$v_list = $archive->create($v_dir, PCLZIP_OPT_REMOVE_PATH, $v_remove);
if ($v_list == 0) {
//如果有錯誤終止程式
die("Error : ".$archive->errorInfo(true));
}else{
// 成功的話下載檔案到client端
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename="".$filename.""");
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($filepath.$filename));
ob_end_flush();
readfile($filepath.$filename);
unlink($filepath.$filename); //下載完成後刪掉主機上的壓縮檔
}
zip上傳後解壓縮
表單
<form id="myform" method="post" action="接收程式.php" enctype = "multipart/form-data">
<input type="file" name="uploadTpl" />
<input id="uploadTmpBtn" type="button" value="上傳壓縮檔" />
</form>
接收程式
if (isset($_FILES['uploadTpl'])) {
$uploadDir = dirname(__FILE__)."/"; //上傳目標資料夾
if ($_FILES['uploadTpl']['size']> 0){
$filename = $_FILES["uploadTpl"]["name"];
if(strrchr($_FILES['uploadTpl']['name'],".") == ".zip") {
copy($_FILES["uploadTpl"]["tmp_name"], $uploadDir.$_FILES['uploadTpl']['name']);
//上船後解壓縮到目前的路徑下
$archive = new PclZip($uploadDir.$_FILES['uploadTpl']['name']);
$v_list = $archive->extract(PCLZIP_OPT_PATH, $uploadDir); /*換成其他路徑即可*/
//解壓完後把zip檔刪掉
unlink($uploadDir.$_FILES['uploadTpl']['name']);
if ($v_list == 0) {
//如果有錯誤終止程式
die("Error : ".$archive->errorInfo(true));
}else{
$optionvalue = str_replace(".zip","",$_FILES['uploadTpl']['name']);
echo '0||<option value="'.$optionvalue.'" selected>'.$optionvalue.'</option>';
}
}else{
echo '只允許zip檔案格式!';
}
}
}else{
echo "無任何資料上傳!";
}
另外,如果要透過jquery的ajax來進行post動作,ajax要有一些設定
<script>
$(function(){
$("#uploadTmpBtn").on("click",function(){
var fdata = new FormData(document.getElementById("myform"));
$.ajax({
type: 'POST',
url: '接收程式.php',
cache: false,
enctype: 'multipart/form-data',
processData: false, // tell jQuery not to process the data
contentType: false, // tell jQuery not to set contentType
data: fdata
}).done(function( data ) {
//成功後的動作
console.log(data );
}).fail(function( textStatus ) {
//失敗後的動作
console.log(textStatus);
});
})
})
</script>
