I`ve got a big Problem with the "zip_entry_read" function, and I don`t unterstand what I did wrong.

I tried to write a function, wicht reads all zip Entries of a file into an Array. It worked, I can read alle Methadata from this array.

But when i try to read the content, I always get nothing.



This is an example whre you can see whats the problem:



when I read 10 Bytes content IN the funktion, it works, but when I try the same with the returnvalue (or with the refference of the entries), it won`t work.



With the result of the function, I can also read all the methadata (filename, size ...) but only the Content, seems to be emty after the function.



<?php

  require("zip_funct.inc.php");



  function test(&$zip_entry = null)

  {

    $zip = zip_open("test.zip");

    while( $tmp[] = zip_read($zip) );

    array_pop($tmp);

    $zip_entry = $tmp;



    $n = 2;

    var_dump($zip_entry);



    $buf = zip_entry_read($zip_entry[$n], 10);

    echo "CONTENT:\n------------------\n".$buf."\n";

    echo "------------------\n";

    echo "Name:               " . zip_entry_name($zip_entry[$n]) . "\n";

    echo "Actual Filesize:    " . zip_entry_filesize($zip_entry[$n]) . "\n";

    echo "Compressed Size:    " . zip_entry_compressedsize($zip_entry[$n]) . "\n";

    echo "Compression Method: " . zip_entry_compressionmethod($zip_entry[$n]) . "\n";



//    echo fread($result, 50);

    return $zip_entry;

}



// ##################################################



//  test($zip_entry);  // try to get the zip_entries via Refference

    $zip_entry = test();  // try to get zip_entries s return value



    $n = 2;

    var_dump($zip_entry);



    $buf = zip_entry_read($zip_entry[$n], 10);

    echo "CONTENT:\n------------------\n".$buf."\n";

    echo "------------------\n";

    echo "Name:               " . zip_entry_name($zip_entry[$n]) . "\n";

    echo "Actual Filesize:    " . zip_entry_filesize($zip_entry[$n]) . "\n";

    echo "Compressed Size:    " . zip_entry_compressedsize($zip_entry[$n]) . "\n";

    echo "Compression Method: " . zip_entry_compressionmethod($zip_entry[$n]) . "\n";

?>



The screenoutput looks like this:



array(8) {

  [0]=>

  resource(61) of type (Zip Entry)

  [1]=>

  resource(62) of type (Zip Entry)

// and a lot other entries

}

CONTENT:

------------------

<html>

<h

------------------

Name:               tmp.html

Actual Filesize:    1136

Compressed Size:    360

Compression Method: deflated

array(8) {

  [0]=>

  resource(61) of type (Zip Entry)

  [1]=>

  resource(62) of type (Zip Entry)

// and a lot other entries

}

CONTENT:

------------------



------------------

Name:               tmp.html

Actual Filesize:    1136

Compressed Size:    360

Compression Method: deflated



And this output shows, that the returnvalue of the function still as a valid ressource and still returns the correct methadata, but the content is empty.



I try to solve this problem since weeks and I realy need help. If anybody has an idea whats the Problem, please notice hear.

When reading from a zip file if the initial call to zip_entry_read() returns false it would be advisable to run mkdir with the file name since it it very likely that the zero length file was a directory and attempts to save the files within the directory will fail if you dont create it first
