How is PHPMailer different from regular mail() functions??

Question

Iron

Why PHPMailer is needed if regular mail() works well

Answer 1

Forget the memory count, memory doesn't matter!
Get gtx! And here's why you should take it:
1) Process technology - 16nm, in amd - 14
2) GPU frequency - 1506 MHz versus 1284 MHz
3) Video memory frequency (which is much more important than its number) - 8k, versus 7k for AMD
And more Lots of other cool stuff from nvidia!

Answer 2

Take it with 6GB of memory - three gigabytes will not be enough for some modern games, for example: https://www.dns-shop.ru/product/9af2bfa66dbc3330/v...

Answer 3

In such a price range, I would look after myself bu 980. It will be in terms of performance like 1060 6GB, and the price is 12-15k. They have 4GB of memory.
But it should be borne in mind that these are additional troubles for carrying out any checks for the full performance of the card.

Answer 4

The function mail()in PHP essentially calls the mail program built into the system - by default, this is sendmailin linux (it is also possible to use qmail, postfix, but for this you must first configure PHP through the .ini file).

If you're a heavy user of a feature mail()in PHP development and haven't run into problems using it on hosts or on your own servers without a properly configured environment, then mail()it's perfect for you. And when you run into problems or want to have more features out of the box, the advantages of PHPMailer and other specialized libraries become obvious.
