What will be the output of the following PHP code?<?phpy = 20;if (y && 1||1) print "PHP MCQ TEST!" ;else print "Welcome to Marwadi University!";?>Group of answer choicesWelcome to Marwadi University!errorPHP MCQ TEST!no output
Solution
The output of the given PHP code will be "PHP MCQ TEST!".
Here's the step by step explanation:
- The variables y are assigned the values 10 and 20 respectively.
- The 'if' statement checks two conditions: whether y and whether 1 is truthy. The '&&' operator is a logical AND, meaning both conditions must be true for the entire statement to be true. However, in this case, y, so this part of the condition is false.
- The '||' operator is a logical OR, meaning only one of the conditions needs to be true for the entire statement to be true. In this case, the second part of the condition is just '1', which is always truthy in PHP.
- Therefore, even though the first part of the condition is false, the entire condition is still true because of the OR operator. So, the code within the 'if' statement is executed, printing "PHP MCQ TEST!".
- If the entire condition had been false, the code within the 'else' statement would have been executed, printing "Welcome to Marwadi University!". But in this case, that doesn't happen.
