php: catch exception and continue execution, is it possible?

Question

Is it possible to catch exception and continue execution of script?

Answer 1

Sure, just catch the exception where you want to continue execution...

  try
  {
      SomeOperation();
  }
  catch (SomeException $e)
  {
      // do nothing... php will ignore and continue    
  }

Of course this has the problem of silently dropping what could be a very important error. SomeOperation() may fail causing other subtle, difficult to figure out problems, but you would never know if you silently drop the exception.

Answer 2

Sure:

try {
   throw new Exception('Something bad');
} catch (Exception $e) {
    // Do nothing
}

You might want to go have a read of the PHP documentation on Exceptions.

Answer 3

Yes.

try {
    Somecode();
catch (Exception e) {
    // handle or ignore exception here. 
}

however note that php also has error codes separate from exceptions, a legacy holdover from before php had oop primitives. Most library builtins still raise error codes, not exceptions. To ignore an error code call the function prefixed with @:

@myfunction();

Answer 4

Yes but it depends what you want to execute:

E.g.

try {
   a();
   b();
}
catch($e){}

c();

c() will always be executed. But if a() throws an exception, b() is not executed.

Only put the stuff in to the try block that is depended on each other. E.g. b depends on some result of a it makes no sense to put b after the try-catch block.
