Hi there,

I have an interesting problem, where it would be important to detect whether or not a particular string contains executable commands (ie. via eval).

For example, I'd need:

"echo a b c"

to return true

whereas

"a b c"

would not.

I'd guessed that I could compare highlight_string output, but this may introduce unnecessary complexity. Short of building a list of absolutely all PHP commands, I was wondering if anyone here had a quick trick I could use!

Always open to suggestions, and thanks!
Alex
