I have a index.php file, i include functions.php

functions.php

function myfunction($var1, &$array_work) {



  $array_work = array();

  global $array_work;



  array_push($array_work, "Test");

}





$var1 = 2;

myfunction($var1, $array_work);



print "<pre>";

print_r($array_work);

print "</pre>";

Everthing works, when i call the file direct (functions.php), but when i include this file into the index.php it doesnt work?

Warning: array_push() expects parameter 1 to be array, null given in

this works now for me:

function myfunction($var1, &$array_work) {

  array_push($array_work, "Test");

}





$var1 = 2;

$array_work = array();

myfunction($var1, $array_work);



print "<pre>";

print_r($array_work);

print "</pre>";

My Answer:
$var2) {
global $myGlobalVar;
$result = $var1 + $var2 + $myGlobalVar;
return $result;
}

$myGlobalVar = 10;
$var1 = 5;
$var2 = 3;

echo myfunction($var1, $var2);
?>

In this code, we have a function called myfunction that takes two parameters $var1 and $var2, and also uses a global variable $myGlobalVar. The function calculates the sum of $var1, $var2, and $myGlobalVar and returns the result.

Before calling the function, we set the value of $myGlobalVar to 10, $var1 to 5, and $var2 to 3. Then we call the myfunction with $var1 and $var2 as arguments.

When we run this code, it will output the result of the sum of $var1, $var2, and $myGlobalVar, which is 18.
