In the legacy codebase that I am working on, there is a condition evaluator which accepts user input to build a condition. This condition is then evaluated at run-time using php eval(). What is the best way to resolve this without using eval.
For e.g. I have a condition “1>0” entered by the user in the UI. This has to evaluated and the result (true in this case) returned. Any suggestions?
Let know if the problem seems vague, I would try and explain better.
The evalMath parser over on PHPClasses provides a safe framework for evaluating this type of expression.
