php代码逻辑版本

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?

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();
}
