WHY PHP NO WORK

DEAR PROG

WHY NO WORK?
SICP WAS NO HELP.

url_setopt($curl, CURLOPT_POSTFIELDS,"name_f="$_POST["username1"]");
url_setopt($curl, CURLOPT_POSTFIELDS,"name_l="$_POST["username2"]");
url_setopt($curl, CURLOPT_POSTFIELDS,"pass0=$_POST["pass"]");
url_setopt($curl, CURLOPT_POSTFIELDS,"pass1=$_POST["pass"]");
url_setopt($curl, CURLOPT_POSTFIELDS,"email=$_POST["email"]");

No, that's not faster.
That's buggier.

Slower:
if (streln($str) >= 5) // ...
Faster:
if (isset($str[5])) // ...

this is wrong if the length of the string is 5.

HOH GOD THE FUCKING FAIL I WANT TO FUCKING HIT YOU
I HATE YOU
