Get contents of zip file php

ZipArchive::getFromName

The length to be read from the entry. If 0 , then the entire entry is read.

• ZipArchive::FL_UNCHANGED
• ZipArchive::FL_COMPRESSED
• ZipArchive::FL_NOCASE

Return Values

Returns the contents of the entry on success or false on failure.

Examples

Example #1 Get the file contents

$zip = new ZipArchive ;
if ( $zip -> open ( ‘test1.zip’ ) === TRUE ) echo $zip -> getFromName ( ‘testfromfile.php’ );
$zip -> close ();
> else echo ‘failed’ ;
>
?>

Example #2 Convert an image from a zip entry

$z = new ZipArchive ();
if ( $z -> open ( dirname ( __FILE__ ) . ‘/test_im.zip’ )) $im_string = $z -> getFromName ( «pear_item.gif» );
$im = imagecreatefromstring ( $im_string );
imagepng ( $im , ‘b.png’ );
>
?>

The handling of file names containing non-ASCII characters is undocumented. It seems that this function calls and therefore expects DOS encoding in the zipfile but UTF-8 encoding for the name. If the zipfile uses UTF-8 names (Pkzip 4.5 / Winzip 11.2), this function fails. Use getFromIndex instead as a workaround.

When passing to the method explicit string which contains a relative path (inside the ZIP archive), e.g. ‘path/to/file.php/’ please make sure you used single quotation mark (‘) not the double one («). Double quotation mark produce FALSE (at least at Windows machine) giving no further hints what gone wrong.
Also, please make sure that the path delimiters used inside your ZIP file is backslash or forward slash since it’s make a difference in this place too.
I hope I saved you a headache while working with this (so far) unmentioned «feature» 🙂

  ZipArchive::getStream

  Get a file handler to the entry defined by its name. For now, it only supports read operations.

  Parameters

  The name of the entry to use.

  Return Values

  Returns a file pointer (resource) on success or false on failure.

  Examples

  Example #1 Get the entry contents with fread() and store it

  $contents = » ;
  $z = new ZipArchive ();
  if ( $z -> open ( ‘test.zip’ )) $fp = $z -> getStream ( ‘test’ );
  if(! $fp ) exit( «failed\n» );

  while (! feof ( $fp )) $contents .= fread ( $fp , 2 );
  >

  fclose ( $fp );
  file_put_contents ( ‘t’ , $contents );
  echo «done.\n» ;
  >
  ?>

  Example #2 Same as the previous example but with fopen() and the zip stream wrapper

  $contents = » ;
  $fp = fopen ( ‘zip://’ . dirname ( __FILE__ ) . ‘/test.zip#test’ , ‘r’ );
  if (! $fp ) exit( «cannot open\n» );
  >
  while (! feof ( $fp )) $contents .= fread ( $fp , 2 );
  >
  echo » $contents \n» ;
  fclose ( $fp );
  echo «done.\n» ;
  ?>

  Example #3 Stream wrapper and image, can be used with the xml function as well

  $im = imagecreatefromgif ( ‘zip://’ . dirname ( __FILE__ ) . ‘/test_im.zip#pear_item.gif’ );
  imagepng ( $im , ‘a.png’ );
  ?>

  Here a way to handle specific files from a zip archive without full extract :

  $zip_file = ‘/path/to/file.zip’ ; // I wan to get stream a CSV files

  $zip = new ZipArchive ();
  $zip -> open ( $zip_file );
  for ( $i = 0 ; $i < $zip ->numFiles ; $i ++) < // Check file by file
  $name = $zip -> getNameIndex ( $i ); // Retrieve entry name
  $extension = pathinfo ( $name , PATHINFO_EXTENSION );
  if ( $extension === ‘csv’ ) < // I want to handle csv files
  $stream = $zip -> getStream ( $name ); // No stream index access before PHP 8.2
  // Starting PHP 8.2 $zip->getStreamIndex() or $zip->getStreamName()
  // Do stuff with $stream
  // .

  How To Read Zip Files In PHP (Simple Examples)

  Welcome to a quick tutorial on how to read zip files in PHP. So the old zip functions are deprecated in PHP 8, how do we read files using Zip Archive then? This has caused some confusion, but it is actually very straightforward.

  To read zip files in PHP, we can use statIndex() to get the file statistics, and getFromName() to directly read a file.

  • $zip = new ZipArchive;
  • $zip->open(«FILE.ZIP», ZipArchive::RDONLY);
  • $entries = $zip->count();
  • for ($i=0; $istatIndex($i); >
  • $content = $zip->getFromName(«FILE-IN-ZIP.TXT»);
  • $zip->close();

  That should cover the basics, but if you need more concrete examples – Read on!

  TLDR – QUICK SLIDES

  

  TABLE OF CONTENTS

  PHP READ ZIP FILE

  All right, let us now get into the examples of how to read a zip file in PHP.

  1) READ FILE LIST OR INFORMATION

  open($file, ZipArchive::RDONLY) !== true) < exit("Failed to open $file"); >// (B) LOOP THROUGH EVERY FILE & FOLDER - DISPLAY INFORMATION $total = $zip->count(); for ($i=0; $istatIndex($i)); > // (C) CLOSE ZIP $zip->close();

  This should be pretty self-explanatory, and how Zip Archive works is actually somewhat like an array – Each file or folder inside the zip archive will have an index number. To get a whole list of files/folders inside the archive, we can simply use a for loop to run through them and statIndex() to fetch the information.

  2) READ FILE IN ZIP ARCHIVE

  open($file, ZipArchive::RDONLY) !== true) < exit("Failed to open $file"); >// (B) DIRECTLY READ FILE USING INDEX $content = $zip->getFromIndex(0); echo "$content
  "; // (C) OR USE GET FROM FILE NAME $content = $zip->getFromName("second.txt"); echo "$content
  "; // (D) CLOSE ZIP $zip->close();

  To read the contents of a file inside a zip archive, we can either use getFromIndex() or getFromName() . But there will be a problem dealing with large files in this one. While both functions accept a second parameter to restrict the number of bytes read, there is just no way to open it as a file stream – The best way to deal with large files is still to unzip it and use fgets() instead.

  3) LEGACY ZIP READ

   // (B) READ FILES while ($entry = zip_read($zip)) < // (B1) GET FILE NAME & SIZE $name = zip_entry_name($entry); $size = zip_entry_filesize($entry); echo "$name - $size bytes
  "; // (B2) READ FILE DIRECTLY if ($name == "first.txt") < if (zip_entry_open($zip, $entry)) < $contents = zip_entry_read($entry); echo "$contents
  "; zip_entry_close($entry); > else < echo "Cannot open first.txt"; >> > zip_close($zip);

  Yes, the old zip functions are deprecated in PHP 8 (they still work but will eventually disappear). I shall not explain too much on this example but leave it here as “legacy support”… Do not use this method anymore, unless you have to support the older PHP versions.

  EXTRA) HOW TO UNZIP FILE

  open("TEST.ZIP") === TRUE) < $zip->extractTo("DESTINATION/FOLDER/"); $zip->close(); >
