I have huge problem.
I have a task to put in database information about products. All information's except price are in XML file that is big 100mb .
In another file there are information's about price of that product. That is CSV file with size about 200mb
In simple logic
But i Cannot do that. Problem is in SIZE .
I manage to parse XML and put it in array, but I cannot handle CSV file. If there is 1000 products, for each product he need to parse CSV file (that CSV file have more than 30.000.000 lines). I cannot parse that CSV one, much less 1000.
I need suggestion how to solve this problem
Looks like a job for a database to me. Load both files into a database and then do a simple join.
Use XMLReader for the XML , SplFileObject for the CSV .
Do not keep the information in memory. Write it directly into a database like MySQL or SQlite. After all the data is imported you can use SQL to aggregate it.
