I think the OP means why not how.

 

First, it is important to note that print is not a function so may cause confusion when called like one! The parentheses in the example code above are meaningless and only serve to give the false impression that the line of code will behave like normal function calls.

 

When PHP evaluates the following line:

 

echo print('3').'2'.print('4');

It might as well be:

 

echo print '3' . '2' . print '4';

Both are identical. If we were to use parentheses to represent what is evaluated together it would look like:

 

echo (print '3' . '2' . (print '4'));

 

Working through this as PHP does:

1. Concatenate "3" with "2" to get "32"

2. Print "4"

3. Concatenate "32" with the return value from the second print (integer 1) to get "321"

4. Print "321"

5. Echo the return value from the first print (integer 1) so echo "1"

Smells like homework to me. Read your book

[PFMaBiSmAd]

Based on the string of topics being started, several so hastily made they were not even in the correct forum section, it is probably an exam of some kind.

[mrneilrobinson]

many thanks for your help, homework indeed, however in the brief i was asked to use forums.

homework indeed

 

I feel so used. However, you'll have fun explaining things to whoever marks your homework. 

 

Don't forget to tell your teacher/tutor/professor how helpful and nice PHPFreaks people were.

It was an exam, for a job at my company. I found this by searching the answer text!

 

Just registered to say that's a great explanation salathe. Actually the best answer we've had so far
