Dealing with file_get_contents errors?

[python72]

I am using file_get_contents to get file off the internet for  further processing but somtetimes there is error fetching that file off the web in which case it would be nice to try to reload it again but I am not sure what would be best way to do it? How can I jump back on error? I guess there would have to be some jump to label condition, but how do I implement this?

"jump to label"? No. Just no.

 

If you're thinking about timeouts and 500 errors and such, cURL is easier to use than a similar built-in solution using stream contexts.

Otherwise a simple for or while loop is what you want.

[python72]

If I have the following:

$Page = file_get_contents('http://www.google.com/');

The $Page variable would be null till the page loads completely?

Now using the while would I have the following?

$Page=Null;
while($Page == Null){
$Page = file_get_contents('http://www.google.com/');
}

file_get_contents returns false on failure, not null.
