Who said it's wrong? What problem you get?

I add this to demo.php
then it show this "PHP Parse error: syntax error, unexpected T_ECHO, expecting ',' or ';' in /home/lingdecong/php_project/demo.php on line 21
". And the line 21 is echo (true?'true':'t');.

This should evaluate to 'true' of course.

Solution 2

It should (and does) print the string "true".
If you expect it to do otherwise, then you need to look at the PHP ternary operator[^] in more detail.

Solution 3

The error message in your comment suggests that the line before the echo is missing a semi-colon (;) at the end of it.

The ; is not optional in PHP.
