PHP ones are wrong. Hello world in PHP is this:
Hello world!
Hello world!
ECHO 'Hello+World%0A'
RETURN 1
$ echo -n "<?php echo 'Hello World'; ?>" > hello.php
$ php -d vld.active=1 -d vld.execute=0 -f hello.php
line # * op fetch ext return operands
---------------------------------------------------------------------------------
1 0 > ECHO 'Hello+World'
1 > RETURN 1
$ echo -n "Hello World" > hello.php
$ php -d vld.active=1 -d vld.execute=0 -f hello.php
1 0 > ECHO 'Hello+World'
1 > RETURN 1
$ echo "<?php echo 'Hello World'; ?>" > hello.php
$ php -d vld.active=1 -d vld.execute=0 -f hello.php
1 0 > ECHO 'Hello+World'
2 1 > RETURN 1
$ echo "Hello World" > hello.php
$ php -d vld.active=1 -d vld.execute=0 -f hello.php
2 0 > ECHO 'Hello+World%0A'
1 > RETURN 1
