php - remove_before() -


Is there a better way to do the down? (Without the possibility of a fatal error) 

  Before removing the function ($ needle, $ hansstack) {return substr (strstr ($ haystack, $ needle), strlen ($ needle)); }

such as strstr ($ haystack, $ needle) but without the needle in the returned string, and I can also ask if it can also be improved ...

Note that after the last incident of the needle remove the wire after the strips, and before the first appearance of the needle remove before the wire strips.

edit: Example: 

  $ needle = '@@'; $ Haystack = 'one @@ two @@ three' ;; ($ Needle, $ hansstack); // a return @ @ two before removing ($ needle, $ hansstack): // return two @@ three

edit: I will leave for reference.

There are two things about the function Written:

They have an error handling For example, in remove_before: due to the green color in the dry drain is due to passing the false as the first argument of substr i do it Have not tried, but I'm pretty sure this would be a runtime error.

Therefore: 

  Before removing the function ($ needle, $ harestack) {$ pos = strpos ($ haystack, $ needle)); // No needle is found (wrong === $ pos) $ green stack; Return substrate ($ histoc, $ position + strollon ($ needle)); }

and so on, after remove_after :

function deleted ($ Needle, $ Harestack) {$ pos = Strrpos ($ yesstack, $ needle); // No needle is found (wrong === $ pos) $ green stack; Return substrate ($ haystack, 0, $ pos); }

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
