Question

I’m trying to parse a large csv file and perform some operations on that data before saving it into the DB. However, I get a fatal error denoting that the memory limit has been reached. Is there any way I can run a function to save the current row number/pointer of the csv file so that the next time I run the script I can resume from that point?

Answer 1

No, there isn’t. You should (for example) process the file line-by-line

$f = fopen($csv, 'rb');
while ($row = fgetcsv($f)) {
  // Do something with line
  // for example push it into a db 
}
fclose($f);

This way you only have in memory, what you currently need.
