centos 6 安裝 zip 模組

用PECL的方式安裝
步驟1.
yum -y install pcre-devel gcc zlib zlib-devel
步驟2.
pecl install zip
快好了~~步驟3.
請在php.ini中加上
extension_dir = /usr/lib64/php/modules/
extension=zip.so;

最後：
service httpd restart

成功以後phpinfo()會多出這個：

使用 php zip 函數將文件打包成 zip 檔


<?php 
$str = "test...test..."; //檔案內容
$filename = "testfile"; //檔案名稱
$filename_txt = $filename . ".txt";
$filename_zip = $filename . ".zip";
$dir = "/var/www/html"; //暫存檔目錄
$pwd_txt = $dir . "/" . $filename_txt;
$pwd_zip = $dir . "/" . $filename_zip;
$res_file = file_put_contents($pwd_txt, $str);
unset($str);
if(FALSE === $res_file){
    die("產生檔案失敗");
}else{
    $zip = new ZipArchive;
    $res_zip = $zip->open($pwd_zip, ZipArchive::CREATE);
    if (TRUE === $res_zip) {
        $zip->addFile($pwd_txt, $filename_txt);
        $zip->close();
        unlink($pwd_txt);
    }else{
        unlink($pwd_txt);
        die("產生壓縮檔失敗");
    }
}

if (file_exists($pwd_zip)) {
    header('Content-Description: File Transfer');
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename='.basename($pwd_zip));
    header('Expires: 0');
    header('Cache-Control: must-revalidate');
    header('Pragma: public');
    header('Content-Length: ' . filesize($pwd_zip));
    readfile($pwd_zip);
    exit;
}

另外也能將文件加入到 zip 檔中
<?php
$zip=new ZipArchive;
    $res=$zip->open('test.zip',ZipArchive::CREATE);
    if($res===TRUE){
        $zip->addFromString('image.txt','file content goes here');
        $zip->close();
        echo 'ok';
    }else{
        echo 'failed';
    }
header('Content-type: application/octet-stream');
header('Content-Transfer-Encoding: Binary');
header('Content-disposition: attachment; filename=test.zip');
 
readfile(test.zip);
unlink(test.zip); 
exit;

執行時可以利用 shell php指令來執行 php 檔，就可以在目錄底下發現到 xxx.zip 檔案
