php - Why multiple inserts do not work? -


I try to populate my mongodb collection with large data for testing performance I am I first tried to do it in a loop like this: 

  while ($ i <= 1000000) {$ collection-> Insert ($ _ POST); }

And then I tried this way: 

  $ collection-> Insert ($ _ POST); $ COLLECTION- & gt; Insert ($ _ post); ... $ collection-> Insert ($ _ POST);

But only one row was added in both cases. Why is it like this?
