Use PHP to package zip and download features

This article mainly introduces the PHP implementation package zip and download function, code simple and easy to understand, very good, with a certain reference value, need to refer to the friend

The specific code looks like this:

$file _template = fcpath. ' Canddata/cand_picture.zip ';//before this you must create a new empty zip package (must exist) in your project directory $downname = $card. Zip ';//the ZIP file name you are about to pack $file_name = fcpath. ' canddata/'. $card. Zip ';//pack your zip after the directory $result = copy ($file _template, $file _name);//The original project directory exists zip copy a new to another directory and rename (can be in the original directory) $zip = New Ziparchive ();//Create an object if ($zip->open ($file _name, ziparchive::create) = = = TRUE) {//Open the empty zip package after you copy $zip　　Addemptydir ($card);//Create an empty folder in the Zip package, return TRUE on success, or return FALSE on Failure//The following is my scene business processing, can be processed according to my own scene (I will pack all the pictures) $i = 1; foreach ($cand _photo as $key 3 = $value 3) {$file _ext = explode ('. ', $value 3[' cand_face '));//Gets the suffix of the picture $zip->ad Dfromstring ($card. ' /'. $card. ' _ '. $i. '.　　$file _ext[3], file_get_contents ($value 3[' cand_face '));//(Rename the image, get to the picture of the binary stream) $i + +;　　} $zip->close (); 　　$FP =fopen ($file _name, "R"); 　　$file _size=filesize ($file _name);//The Header ("Content-type:application/octet-stream") to get the file's byte//download file to use; 　　Header ("Accept-ranges:bytes");　　Header ("Accept-length:". $file _size); Header ("ConTent-disposition:attachment; 　　Filename= $downname "); $buffer = 1024; Sets the number of bytes read at a time, each time it is read, the output data (that is, returned to the browser) $file _count=0; Total bytes read//Return data to the browser if the download is complete, stop the output, if it is not downloaded, it will always be output.          Determine whether the download completed while (!feof ($fp) && $file _count< $file _size) {$file _con=fread ($fp, $buffer) based on the size of the file's bytes;          $file _count+= $buffer;      echo $file _con; 　　} fclose ($FP); 　　After the download is complete, delete the compressed package, the temporary folder if ($file _count >= $file _size) {unlink ($file _name); }}
