PHP - Output and String Handling

You want to output a list of names stored in an array using echo. Which approach correctly outputs all names separated by commas?

Aecho join($names);

Becho implode(", ", $names);

Cecho $names;

Decho array_to_string($names);

Step-by-Step Solution

Solution:

Step 1: Understand how to convert array to string
PHP's implode function joins array elements into a string with a separator.
Step 2: Check each option
echo implode(", ", $names); uses implode correctly with comma and space separator. echo join($names); uses join incorrectly without separator. echo $names; tries to echo array directly (error). echo array_to_string($names); uses a non-existent function.
Final Answer:
echo implode(", ", $names); -> Option B
Quick Check:
Use implode to join array elements [OK]
