PHP supports concatenation operator(. and .=), that is used to combine strings.

Here is an example for strings(here "welcome" and "to kolkata") combination using (.) operator:

<html>
<body>
<?php
$a="welcome";
$b="to kolkata";
$c=$a.$b;
echo $c;
?>
</body>
</html>

Output: welcometo kolkata

Below is an example for strings combination using (.=) operator:

<html>
<body>
<?php
$a="welcome";
$b="to kolkata";
$b.=$a;//here $b.=$a means $b=$b.$a
echo $b;
?>
</body>
</html>

Output: to kolkatawelcome

Here is a program to check where a string is a palindrome or not:

NB: A string is a palindrome if the string that reads the same backward as forwards, e.g., madam, using strcmp() function.

<html>
<body>
<?php
$a="madam";
$b=strrev($a);
if(strcmp($a,$b)==0)
{
echo "The string is a palindrome";
}
else
{
echo "The string is not a palindrome";
}

?>
</body>
</html>

Output: The string is a palindrome
