Hi Julien.
What about the following example?
try {
$foo = $bar->getObject();
$foo->doSomething()
} catch(Exception $e) {
continue // Or whatever shall be used
}
When $bar->getObject throws an Exception no $foo is set. So the next
line will result in a "PHP Fatal error: Call to a member function
doSomething() on a non-object".
So where shall the "continue" actually continue? In the line after the
exception was thrown? In the line following the last line $foo was
accessed in?
Or would something like
CreateTryCatchBlockForEverySingleLine {
$bar->doOne();
$bar->doNext();
$bar->doSomethingElse();
} catch(Exception $e) {
doSomethingWithTheException($e);
}
resulting in
try {
$bar->doOne();
} catch(Exception $e) {
doSomethingWithTheException($e);
}
try {
$bar->doNext();
} catch(Exception $e) {
doSomethingWithTheException($e);
}
try {
$bar->doSomethingElse();
} catch(Exception $e) {
doSomethingWithTheException($e);
}
be more what you are talking about?
Regards
Andreas
