This article mainly introduces the implementation of batch compression, packaging and downloading of files in PHP. Interested friends can refer to it. I hope it will be helpful to everyone.

The code is as follows:

<?php 
$filename=&#39;test.zip&#39;; //最终生成的文件名（含路径） 
if(file_exists($filename)){ 
  unlink($filename); 
} 
//重新生成文件 
$zip=new ZipArchive(); 
if($zip->open($filename,ZIPARCHIVE::CREATE)!==TRUE){ 
  exit(&#39;无法打开文件，或者文件创建失败&#39;); 
} 
$datalist=array(&#39;try.php&#39;,&#39;zip_class.php&#39;); 
foreach($datalist as $val){ 
  if(file_exists($val)){ 
    $zip->addFile($val); 
  } 
} 
$zip->close();//关闭 
if(!file_exists($filename)){ 
  exit(&#39;无法找到文件&#39;); //即使创建，仍有可能失败 
}
