Concat Strings

Two strings can be concatenated by using the operator dot (.). Let's see this with an example:

<?php
$str1="Learn";
$str2="PHP";
echo $str1.$str2;
?>

The result for the above echo statement will be:

LearnPHP

Now look at the script given below:

<?php
$str1="Learn";
$str2="PHP";
echo $str1." ".$str2;
?>

The result of this script will be:

Learn PHP

Here, we used the concatenation operator twice to include another string i.e. a blank.
