Answer 1

If i read the code correctly you are writing the string seperated by \t but try to explode with spaces, use:
explode("\t", $string);

Answer 2

You could use fgetcsv, since you're just doing a standard tab-delimited input file. Given your sample file of:
no [tab] username [tab] password
1 [tab] srinivas [tab] malayappa
then
$lines = array();
$fh = fopen('testfile.txt', 'rb') or die ("can't open testfile.txt");
while($lines[] = fgetcsv($fh, 0, "\t") { // no line length limit, tab delimiter)
...
}
will give you
$lines = Array(
0 => Array(
0 => 'no ',
1 => 'username ',
2 => 'password '
),
1 => Array(
0 => 1,
1 => 'srinivas ',
2 => 'malayappa'
)
);

Answer 3

You're exploding on whitespace. Unless there is whitespace in the string your exploding then no, it won't work.
Try using the code markup to make your code a little more readable in order to get better quality responses from people.
