Suppressing errors in PHP

I'm running a PHP script every night using a cron service. Everything it outputs will be printed to an log file for debug prepossess. The file I use will retrieve xml's from a different site using the function 'file_get_contents()'. But the function can return an error which I really don't want to see as I am already showing a custom error.

Quick example of my piece of code:

$buffer = @file_get_contents('http://xx:xx@xx/xml/xx?offset=2') or print('retry in 5 seconds');

if($buffer === false) {
  sleep(5);
  $buffer = @file_get_contents('http://xx:xx@xx/xml/xx?offset=2') or print('error notice');
}

The problem is the first one will trigger an error and print it'll retry in 5 seconds. How can I correctly suppress the thrown error?

I have an error handler, but I prefer not to catch this error separately.

Edited: My solution wasn't to change the error_reporting, but to catch the error message. If it starts with 'file_get_contents()', no error will be thrown. This is not the best way, but will do the job for me.

You can try inserting this at the start:

error_reporting(0);

Then after the code with the error/warning:

error_reporting(E_ALL ^ E_WARNING);

Okay, never ever use the @-operator.

In PHP you have two options available: either use a custom error handler or use try/catch.

Since file_get_contents doesn't throw an exception, you can only use the first approach.

You can set an error handler like this: http://php.net/set-error-handler and then act correctly (log something or return a custom error code).

If you just want to turn of all errors use error_reporting(0) or if you just want to turn off a specific category use error_reporting(E_ALL ^ E_WARNING) (all but warnings) or specifcy them explicitely error_reporting(E_WARNING | E_NOTICE) (warnings and notices).

I prefer the first approach, since when you just disable it you have no idea of what's going on in your code.

Add @ before command or use try catch.
