To concatenate two strings in PHP, the code is as follows −

Example

 Live Demo

<?php    $a = 1.967;    $b = 1.969;    $res = $a." and ".$b;    echo " $res 
";    if((round($a, 2)) == (round($b, 2))) {       echo "
Both the values are equal!";    } else {       echo "
Both the values aren\'t equal";    } ?>

Output

This will produce the following output−

1.967 and 1.969 Both the values are equal!

Example

Let us now see another example −

 Live Demo

<?php    $val1 = 'Jack';    $val2 = 'Sparrow';    echo "First Name = $val1 
";    echo "Second Name = $val2 
";    $res = $val1.$val2;    echo "Concatenation = $res 
"; ?>

Output

This will produce the following output−

First Name = Jack Second Name = Sparrow Concatenation = JackSparrow
