Commas in echo
This might be the first time you are seeing this. you can echo something like

PHP Code:


			
$str = 'sentence.';

echo 'This ','is ','a ',$str;

it'll print This is a senetence.. Yes, it works like concatenation but it does not concate strings, it just print everything to buffer.

and if you do

PHP Code:


			
$str = 'sentence.';

echo 'This '.'is '.'a '.$str;

while using periods, it'll first concatenate strings and then print them out.

So, using commas is more faster than using periods.

Note: it only works in echo.
YOU CANNOT DO THIS::
$str = 'This ','is ','a ','sentence.';//THIS IS WRONG SYNTAX
