Question

This is my scenario:

• I upload a zip file
• Check each file in zip file
• If file != image, then move file to destination
• if file == image, resize image and move to destination

I googled around and seen different solutions, but none where one can process files before saving them at the final destination.

This is the function I got so far:

  // Extract zip file and return files in an array. 
  private function processZip() {
    $zip = new ZipArchive;    
    $tmp_dir = FB_PLUGIN_DIR.'tmp/';

    // Extract files to tmp dir
    if ($zip->open($this->file['tmp_name']) === TRUE) {
      //Check if temp dir exists. If not, create one.
      if (!is_dir($tmp_dir)) {
        mkdir($tmp_dir, 0700);
      }

      $zip->extractTo($tmp_dir);
      $zip->close();

    /* Process extracted files */ 

    foreach(glob($tmp_dir.'*.*') as $filename) {

        // Somehow get MIME type here without using 'finfo' and 'mime_content_type'
        // I haven't installed PEAR and 'mime_content_type' is decapricated.
    }      

      return '1'; // success
    } else {
      return "0"; // fail
    } 
  } 

I’m not sure if I’m going in the right direction here. Somehow I think I should be able to process the files while in the “ZIP loop”.

Is there a way I can read the files in the ZIP file, determin the MIME type and then process file?

I found this example: http://www.java-samples.com/showtutorial.php?tutorialid=985
I think it’s close to what I need. But not sure what to modify.

Answer 1

Decouple your processes. Extract everything from the ZIP file first, then scan the files for image files and process them.

It’s a simpler process, and can be more easily decomposed for dealing with larger zipfiles.
