MaxMind GeoIP2 City csv file is too large and Excel cannot open it and it crashes all editors.
So using shell, is it possible to cound how many rows/records this have? I know “cat” command but how to count the lines of csv? or how possible to know the lines with a separate php code?
what file size are we talking about?
around 180 Mb!
Does your system have a version of the “wc” command that will count words, lines etc?
You could explode by \n and then foreach and cont the loops.
I would recommend you not do this on a live host server, but for localhost it could work.
I recently wrote a script to work with a largish CSV file and had problems.
My work-around was to use ini_set() to throw more memory and time at it.
The CSV was 32 MB not 180 MB and I only tweaked up the value until it worked.
You will likely need “no limit” (and some patience while waiting for it to finish)
ini_set('memory_limit', '512M'); // 4x default
//ini_set('memory_limit', -1); // no limit
I think for a 180 MB file I would add a conditional to the while() to break out of the read() and write() new CSV files of smaller size
