Convert a string to a variable

Recommended Posts

Hi, everyone. So, suppose I have a variable holding a string, like

$var = ln(x);

I wanna be able to numerically integrate that string - I wanna be able to, inside a for statement, calculate ln(x) for some values of x. How do I make PHP understand the value of the string as a statement? Thanks in advance!

Nevermind, achieved that using eval. Thanks again!

I have no idea what you're trying to do, but eval() is probably not the best way.

Use eval() only if you are sure there is no other solution, and only if you are 200% sure your data is safe.
