Hello All,

I am writing some php code where I have a string that I want to be evaluated by php. This is a very simplified example of what I am trying to do on a larger scale, I am just wondering if this is possible:


function getSomeNum()
{
return "23";
}

$funkvar = "getSomeNum()";

echo $funkvar;

Instead of it literally echoing the string: getSomeNum()

I would like it to echo the result of the actual function getSomeNum() or 23.

Is there a way to tell php to evaluate a string,like echo eval($funkvar) and have it give me the result of getSomeNum() which is 23 instead of the literal string "getSomeNum()"?

Some way to make: echo $funkvar and echo getSomeNum() both result in 23;

Instead of echo getSomeNum() = 23
and echo $funkvar = getSomeNum()

Thanks!

Did you try without the double quotes?

That solution will work if I wish to store the value of the result of getSomeNum() into $funkvar. I am looking to store the actual function name as a string getSomeNum() and then be able to have that string be evaluated later on.

I ended up solving the problem with this solution:

<?php

function getSomeNum()
{
return "23";
}


$funkvar = "return getSomeNum();";

echo eval($funkvar);

?>

Putting the return statement before the function name string, allows eval to evaluate that function and return the result.
