PHP echo, one of the common used PHP operators. Echo is used to output a string. You can combine echo with strings and variables, Here are some examples:
$age = 36; $name = 'Milos'; echo "Simple string output"; echo "$name is $age"; echo ''.$name.' is '.$age.''; echo '<h1 class="title">'.$name.' is '.$age.'</h1>'; echo $name,$age;//Milos36
There is no right or wrong method, it comes down to preference or what looks best to you.
