Is there another way to call this function besides using php's eval?
So there's a php function in a database field. Here's what it looks like:
'$put_fname_fn = function($filename) {
return $filename.'.Z';
};'
I'm executing it like this:
$code = fetchFromDatabase(); // Get the function string
eval($code);
$put_fname_fn('MYFILE.TX开发者_JAVA技巧T'); // Convert it to MYFILE.TXT.Z
Is there a more graceful way to call the user function? I try to avoid using eval but I don't another way to do this.
There is no other way to evaluate code in PHP. (You could write the code to a file and include
it, but that's just a hidden eval
.)
Still you should probably reconsider your application design. Evaluating code from the database is a VERY BIG SECURITY RISK: If your database is compromised (using a simple and common SQL injection attack) you at the same time give the attacker arbitrary PHP code execution.
