PHP Strings
Here we play with strings.$myName="My Name is Rocky.";
$myLoc=" I live in jungle";
To concatenate two variables together, use the dot (.) or (,) operator:
<?php
$myName="My Name is Rocky.";
$myLoc="I live in jungle";
echo $myName,' ',$myLoc;
?>
$myName="My Name is Rocky.";
$myLoc="I live in jungle";
echo $myName,' ',$myLoc;
?>
My Name is Rocky. I live in jungle
Note: (,) operator is fast to (.) operator.
