Question

I have a bunch of HTML and PHP code and in the template file it works fine but I’m trying to put it in a PHP function and now when I run the page I get the error Undefined variable: variableName

Here’s some code:

function testFunction()
{
    foreach ($variableName as $variable):
        echo 'tasf';
    endforeach;
}

Inside that function $variableName cannot be found but if I move it outside the function it can be found just fine. I’m doing this within a symfony php template file if it matters.

Answer 1

Simple issue of variable scope. If that variable is defined outside the function then either you need to pass it there or declare it global
