PHP – Append String

To append string to another, in PHP, use string concatenation assignment operator. The concatenation assignment operator which is .= appends the given string with a string.

$string1 .= $string2

<?php
$string1 = "apple";
$string2 = "banana";
$string1 .= $string2;
echo $string1;
?>
