String Concatenation (Cross Ref > Data Structures)

By Mike Prestwood

ASP Classic versus PHP: A side by side comparison between ASP Classic and PHP.

Operators

A language symbol used for assignment, comparison, computational, or as a logical.

String Concatenation

[Other Languages]

ASP Classic: "String Concatenation" & or +

Although you can use either a & or a + to concatenate values, my preference is to use a + because more languages use it. However, if you use & then some type conversions are done for you. If you use + you will sometimes have to cast a value to concatenate it. For example, you will have to use CStr to cast a number to a string if you use the + operator as a concatenation operator.

Syntax Example:

Dim FirstName
Dim LastName

FirstName  = "Mike"
LastName  = "Prestwood"

Response.Write "Full name: " & FirstName & " " + LastName

Response.Write "2+2=" + CStr(2+2)

PHP: "String Concatenation" .

PHP uses a period (.) known as a dot to concatenate strings.

Syntax Example:

$fname = "Mike";
$lname = "Prestwood";

$fullname = $fname . $lname . "
";

echo "My name is " . "Mike.
";
