I have a web url http://www.mycompany.com/archive/myarchive.zip which if accessed will download the file.  There are no security issues or any passwords.  I would like to grab the file using PHP and enumerate through the contents to rename and save individually.

All that you need is in this tutorial:

http://net.tutsplus.com/articles/news/how-to-open-zip-files-with-php/

just start reading from step number 5.


For getting the .zip file from the website you can use the file_get_contents() funtion:

http://php.net/manual/en/function.file-get-contents.php

For save it in your own server use file_put_contents.

After this point you can use the code in the tutorial (from step 5), and just add the renaming routine.

Hope this helps!.

Ok, when I save it on my own server
Private function download_pics ($dl_link){
	$zip = new ZipArchive;
	$getFile = file_get_contents($dl_link);
	$tempFile = file_put_contents($getfile);
	$x = $zip->open($tempFile);
	if  ($x === true){
	  $zip->extractTo('IMG/');
	  $zip->close();
	  unlink($tempFile);
	  } ELSE {
  	  die("<br/>There was a problem unpacking the .ZIP archive.");
	  }
  }

Open in new window

It fails with the error, wondering if I need to save the files physically on my server before I can work with it?

Yes, that's why I suggest you to use a combination of file_get_contents() and file_put_contents().

With the firstone you read the file remotely, with the second one you save it in your server before start working over it.

Other way it will not work.

Well, I did use those two commands you suggested, although I obviously did something incorrectly.  The code I pasted above is the combination of your two suggestions.  You see anything in there I'm missing.

Yes, at line 4:

$tempFile = file_put_contents($getfile);

The file_put_contents function takes 2 arguments, the path to where you will save the file, and the data for the file itself:

http://php.net/manual/en/function.file-put-contents.php

so it should be something like:

$tempFile = file_put_contents("MyTempFile.zip", $getfile);

So, read carefully the tutorial and the Php manual pages for the functions...:

http://php.net/manual/en/function.file-put-contents.php
http://php.net/manual/en/function.file-get-contents.php

Cheers!
