Question

I have a simple question (i guess).
I’m getting the name of the function inside a variable from database. After that, i want to run the specific function. How can i echo the function’s name inside the php file?
The code is something like this:

$variable= get_specific_option;
//execute function
$variable_somesuffix();

The “somesuffix” will be a simple text. I tried all the things i had in mind but nothing worked.

You want variable variables.

Here’s some sample code to show you how it works, and the errors produced:

function get_specific_option() {
    return 'fakeFunctionName';
}

$variable = get_specific_option();

$variable();
// Fatal error: Call to undefined function fakeFunctionName()

$test = $variable . '_somesuffix';

$test();
// Fatal error: Call to undefined function fakeFunctionName_somesuffix()
