How to Copy a Variable From One PHP File to Another

Use PHP to pass variables from one file to another.

PHP (Hypertext Preprocessor), a versatile language commonly used for web development, can be used to transfer variables between files. Many programs written in PHP for the Web, such as a blog platform, typically store variables in a master file and then pull those variables from other files. When this happens, the data pulled from other files can be used in any way desired.

Things You'll Need

• Programming tool (such as Notepad or Dreamweaver)

Instructions

1. Open a program to write PHP code into, such as Notepad or Dreamweaver. Create a new file called "variables.php" and copy the following code into the file:

   <?

   //make 2 variables

   $variableOne = "My info.";

   $variableTwo = "Some other info.";

   ?>

   Save the "variables.php" file and put it on your website.

2. Create another file and call it "seevariables.php" and copy the following code into it:

   <?

   //include the other file so you can use its variables

   include ("variables.php");

   //next, print out the two variables from the file

   echo $variableOne;

   echo "<BR><BR>";

   echo $variableTwo;

   ?>

   Save the "seevariables.php" file and put it on your website.

3. Go to the "viewvariables.php" file on your website in a web browser and you'll see the variables being passed from "viewvariables.php" to "seevariables.php."
