PHP - Loops

Which of the following PHP code snippets correctly demonstrates a do-while loop structure?

Ado { echo 'Hello'; } while (false);

Bwhile (true) { echo 'Hello'; } do;

Cdo echo 'Hello'; while;

Ddo { echo 'Hello' } while true;

Step-by-Step Solution

Solution:

Step 1: Identify correct syntax
The do-while loop must have the do block followed by a while condition ending with a semicolon.
Step 2: Analyze each option
do { echo 'Hello'; } while (false); correctly uses do { ... } while (condition); syntax.
while (true) { echo 'Hello'; } do; incorrectly places do; after a while loop.
do echo 'Hello'; while; misses braces and the condition.
do { echo 'Hello' } while true; misses semicolon after while and lacks parentheses around condition.
Final Answer:
do { echo 'Hello'; } while (false); is syntactically correct.
Quick Check:
Correct syntax requires do { ... } while (condition); [OK]

Quick Trick: Remember: do { } while (condition); ends with semicolon [OK]
