  Dear all,

  My brother and I spent 12 hours working on uploading a 60 MB WML XML file from an old hosted WordPress site to WordPress.com. Here we post the solution

  The problem: A 60 MB WML, and wordpress.com upload limit is 3 MB!.

  We needed to chunk our WML, so we created a nifty PHP script that makes this happen. We share the love. It will create a bunch of files called chunk_*.xml that you will need to manually upload to wordpress.com under Manage… Import.

  The PHP script is pasted below our signature.

  Because of memory and CPU limitations (to avoid 500-errors) run it locally either by using XAMPP on your Windows machine (Daniel’s favorite), or just instaling php-cli on your beautiful Ubuntu box (Alan’s favorite), and doing php index.php

  Of course, you have to name your exported xml file to: XMLFINAL.xml

  Daniel and Alan, your saviours.

  <?php

  //Strings

  $header = “<?xml version=”1.0” encoding=”utf-8”?>” .
  “<rss version=”2.0”
  xmlns:content=”http://purl.org/rss/1.0/modules/content/”
  xmlns:wfw=”http://wellformedweb.org/CommentAPI/”
  xmlns:dc=”http://purl.org/dc/elements/1.1/”
  xmlns:wp=”http://wordpress.org/export/1.0/”>

  $stringXML = $header . $stringXML . $footer;

  $fh = fopen(“chunk_” . $files_chunk . “.xml”, ‘w’);
  fwrite($fh, $stringXML);
  fclose($fh);

  //$chunkXML = undefined ;
  $i = 0;

  $files_chunk++;
  }

  $i++;
