Answer 1

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.

Answer 2

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 3

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'
    )
);
