Concatenate Strings

❮ Previous

Next ❯

String concatenation is used to join two or more strings together into a single string. PHP provides the dot operator (.) for this purpose.

Example

<!DOCTYPE html>

<html>

<body>

<?php

$firstName = "John";

$lastName = "Doe";

// Concatenate strings using the . operator

$fullName = $firstName . " " . $lastName;

echo $fullName; // Outputs: John Doe

</body>

</html>

Try it yourself

An easier and better way is by using the power of double quotes.

By surrounding the two variables in double quotes with a white space between them, the white space will also be present in the result:

Example

<!DOCTYPE html>

<html>

<body>

<?php

$x = "Hello";

$y = "World";

$z = "$x $y";

echo $z;

</body>

</html>

Try it yourself
