In my opinion, concatenation reduces code readability because unlike java(that uses + operator), php uses dot(.) for concatenation consider the following codes: //java String mystr="hello"+"world"; is more readable from: //php $mystr="hello"."world"; if you only need echoing something to output(which is not usually the case in MVC and/or other effective methods), the fastest way is using comma: echo 'hello',$mystr,"blah","blah" ;
