I can't quite tell what you're asking for here, but I assume you mean concatenation. In that case, either of the following would work:

echo "<text>" . $var;

or

echo "<text>{$var}";

Replace

<text>

with the text you want added.

Something like this:

$var = "test";
echo "Value: {$var}";

or:

$var = "test";
echo "Value: " . $var;

would both return:

Value: test

Edit because I saw your comment: Using the escape in a double-quoted string creates a new line. Use that if you want your data to be printed across multiple lines. I.E:

echo "<text>{$var}
";
echo "<text>{$var}
";

would return

(text)(value of $var)

(text((value of $var)

Note the new line that is created.
