$overtime=40

Missing ending semicolon (;)

<?php
$passScore = 210;
$studentName = 'Mike';
$studentScore = 190;
if ($studentScore > $passScore) {
echo 'Congratulations' . $studentName . 'You passed the exam with' . $studentMark . 'mark.';

echo 'Sorry You did not pass the exam. Good luck and Cheers next time. ';
}

echo 'Congratulations' . $studentName . 'You passed the exam with' . $studentMark . 'mark.';

On this line, you have $studentMark, this variable is not defined (created/used) in that program.. It should be replaced with $studentScore.

Use tab for indent code inside { and }, refer my code. Code inside { and } is called code block, must be indented (press TAB key).

Try this code

<?php
$overtime=40;
if ($overtime<=60)
{
$pay_amount=1500;
$medicine=1000;
echo 'Pay Amount ' . $pay_amount .' Medicine ' . $medicine;
}
else
{
$pay_amount=2000;
$medicine=1700;
echo 'pay Amount ' . $pay_amount . ' Medicine ' . $medicine;
}

<?php
$day='Sunday';
if ($day="Sunday") {
    echo 'Have a nice Sunday';
}

else {
    echo 'Have a nice day';
}

In this code when i use == on line no:3

if ($day=="Sunday") {

i am getting the result as FALSE. Why ?

Doubt 2

Is it possible to get the day by using PHP date and time function ?
