php code logic by version

Question

I want a solution something like: Imagine I have try catch block, it works in any php 5.?.? version but with finally block not in any. my code must be like this:

try {

    // some logic

} catch (Exception $ex) {
    // some logic
} finally {
    // other logic
}

but, how can I make so that finally block worked only if php version supports it else ignore? For example:

try {
    // some logic
} catch (Exception $ex) {
    // some logic
}
#if version=5.?.?
finally {
    // other logic
}
#endif

Is there any solution?

If you can make without finally block -- why use finally block? — Deep, Dec 29 '15 at 20:17
if I will throw exception in catch block there always will be executed code inside `finally` nevertheless of `throw` — Arkadi, Dec 29 '15 at 20:34

You can get php version by phpversion method. The only option you have is to write an if statement to check it; if it supports write the whole try-catch-finally block. If it does not, write only try-catch. You can use inline functions to prevent duplicate code. I have no idea why somebody needs this, but for example;

function fncTry(){...}
function fncCatch($exception){...}
function fncFinally(){...}

if($phpVersion == '5.5'){
   try { fncTry(); }
   catch(Exception $ex) { fncCatch($ex); }
   finally { fncFinally(); }
}else{
   try { fncTry(); }
   catch(Exception $ex) { fncCatch($ex); }

   fncFinally();
}

Yes.

phpversion() will return a string of the php version. (Example: "5.6.14")

You can use that to set up your conditional statement.

Question is not about checking php version – u_mulder Dec 29 '15 at 20:16
Since "finally" is only supported in php 5.5 or later, yes, technically, it is a question of which version of php is being used. – P. Gearman Dec 29 '15 at 20:23

i am sorry i'm confused :)

check this

and you could check about phpversion before you make the try catch

if (php version == 5.5 or greater)

you make it with finally

else you make it without finally

sorry i didn't recognize – Alaa M. Jaddou Dec 29 '15 at 20:18
And what function should be checked - `finally`? `finally` is not a function. – u_mulder Dec 29 '15 at 20:18
