How to read that and store into different array and print them out

Answer 1

your code should work as expected. I assume you're bit confused with echo "$userName"; output as it displays Array word. try var_dump($userName) instead

Answer 2

Do exactly as you've done, but change
$userName[] = array(fgets($fh));//Save first line content
$tutorial[] = array(fgets($fh));//Save second line content
to
$userName[] = fgets($fh);//Save first line content
$tutorial[] = fgets($fh);//Save second line content
(no need to keep the subitems in their own seperate array)
and print them out by either using print_r, or iterate through them:
for ($i = 0; $i < count($userName); $i++) {
echo $userName[$i] . " - " . $tutorial[$i];
}

Answer 3

$text = file_get_contents('students.txt');
$text = explode("\n",$text);
$output = array();
foreach($text as $line)
{
$output[] = $line;
}

Answer 4

Use function file() in PHP
file — Reads entire file into an array
$array_lines = file('students.txt');
$count = count($array_lines);
$first_arr = array();
$sec_arr = array();
foreach ($array_lines as $i => $line){
if($i%2) $first_arr[] = $line;
else $sec_arr[] = $line;
}
print_r($first_arr);
print_r($sec_arr);
With file() function every line is read as element in array. You can check it with:
print_r($first_arr);
