Automatic Conversion To String in PHP
A similar conversion will occur with numbers on which we try to perform an operation allowed only for strings:
<?php
$a = 1;
$b = 2;
echo $a . $b; // outputs '12'
?>
Given three variables:
<?php
$a = 1;
$b = 2;
$c = 3;
?>
Add the values of these variables as strings.
