RESOLVED Can global variables be used?

[Maple]

I have the following test PFP snippet. The output from the echo statement shows that the variable has a value of 1. The output from the function says NUL. I realize I could pass the variable as a function argument. This is just a simple test case to see if global variables are supported. I have a larger project that I'm attempting to move into Woody Ad Snippets that relies on global variables. It'll be a bit of work to modify the code to pass these variables as arguments if that's what I need to do.

$testvar = 1;​

​

function testfunc() {​

global $testvar;​

var_dump ($testvar);​

}​

​

echo "testvar is [$testvar]<br>\n";​

​

testfunc();​

Hello.

You must declare the variable global.

global $testvar;
$testvar = 1;

function testfunc() {
    global $testvar;
    var_dump ($testvar);
}

echo "testvar is [$testvar]<br>\n";

testfunc();
