php利用ZipArchive类操作文件的实例
ZipArchive类是专门用于文件的压缩与解压操作的类，通过压缩文件可以达到节省磁盘空间的目的，并且压缩文件体积更小，便于网络传输。
function filestozip($fileList,$filename=''){
if(empty($fileList))return false;
if(empty($filename))$filename=time().'.zip';
$filename = "/uploads/temp/".$filename; // 压缩包所在的位置路径
if(file_exists($filename))return $filename;
$zip = new \ZipArchive();
$zip->open($filename,\ZipArchive::CREATE); //打开压缩包
foreach($fileList as $file){
if(substr($file,0,4)=='http'){
$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 0);
curl_setopt($ch,CURLOPT_URL,$file);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
$fileContent = curl_exec($ch);
curl_close($ch);
$zip->addFromString(basename($file), $fileContent);
}else{
$zip->addFile($file,basename($file)); //向压缩包中添加文件
}
}
$zip->close(); //关闭压缩包]
return $filename;
}有些接口还需要把压缩文件转为base64 便于传输
function ZipFileToBase64String($filename){
$base64 = null;
$fileinfo = fopen($filename,"r");
if($fileinfo){
$filesize = filesize($filename);
$content = fread($fileinfo,$filesize);
$base64 = chunk_split(base64_encode($content));
}
fclose($fileinfo);
return $base64;
}
