Bug description:Eval will crash script when function inside returns a string to
be eval'ed
Description:
------------
The code below shows the problem. Any return statement inside the function
that is supposed to create the code to be evaluated will crash PHP. Not
even Apache will send a header anymore. A white page appears.
If the returned string is stored i a variable first it will work fine. The
quickest fix is a (string) cast inside the eval function.
eval((string)foo());
Test script:
---------------
function foo() {
return 'echo time();';
}
eval(foo());
