Updated php for ammending existing posts

Hi all,

I downloaded CSV importer but was having issues with it creating new posts for every one of my uploads, when what I wanted it to do was to update existing posts that were already uploaded on the system.

I recently updated the CSV importer as per the instructions in this thread https://wordpress.org/support/topic/plugin-csv-importer-overwrite-posts?replies=9

However when i upload the plugin, I get the following error:
Parse error: syntax error, unexpected ‘=>’ (T_DOUBLE_ARROW) in /home/rocomag/public_html/wp-content/plugins/csv-importer/csv_importer.php on line 255

Does any know the cause of this and can you offer any soloutions? I checked the instructions and I followed them as they were described.

Also, if you have any other suggestions about the original problem, which is that I need to upload new meta data to 100’s of my existing posts and pages. I was hoping for some kind of uploader that would help me achieve this without spending too much time on it.
