Why does the comma operator behave differently in PHP echo statements compared to other contexts in the language?

The comma operator in PHP echo statements behaves differently because it concatenates the expressions instead of evaluating them as separate expressions. To solve this issue, you can use the concatenation operator (.) instead of the comma operator when you want to concatenate multiple values in an echo statement.

// Using concatenation operator (.) instead of comma operator
echo "Hello, " . "World!";
