html - How to Run PHP coding dynamically -

i want type php coding in textarea, after submit should run php coding , produce result. possible ?

to upload changes in live, need 2 level approve, if errors occur could't fix quickly, if above thing possible can enable error log, dynamically print array , on...

yes, can post value of textarea , evaluate content php code using eval function, make sure restrict access feature, because it's dangerous if allow random people use it. can simulate online php compiler using ajax calls.
