Question

This is about RAW php coding. I have a page – “config.php” and there are some declarations here.

//config.php

<?php
$myvalue = "This is a test";
include("functions.php");
?>

//functions.php

<?php
function testFunction()
{
   $dd = $myvalue;
   echo $dd;
}
?>

And when I call “testFunction()” from another page like “page.php” I want it to echo “This is a test”. How can I do this? “config.php” is included to “page.php”. Hope the scenario is understandable.

//page.php

<?php
include('config.php');
testFunction();
?>

Answer 1

In the first line of your function, add:

global $myvalue;

Your $myvalue-variable is transfered into functions.php when you include that php-file after declaring the variable, but you have to tell your function to use this global variable.

Your function would look like this:

function testFunction()
{
   global $myvalue;
   $dd = $myvalue;
   echo $dd;
}
