Download the contents of a URL in PHP even if it r

Question

I want to download the contents of a URL using PHP, even if the HTTP response code is 404. file_get_contents will error out, and I wasn't able to find an answer using Google. How can I do this?

Answer 1

You have to configure the stream wrapper to ignore errors:

ignore_errors boolean Fetch the content even on failure status codes. Defaults to FALSE

In other words, do

echo file_get_contents(
    'http://stackoverflow.com/foo/bar',
    false,
    stream_context_create(
        array(
            'http' => array(
                'ignore_errors' => true
            )
        )
    )
);

and you will get the 404 page.

If you want this to be the default behavior for HTTP streams, use

stream_context_set_default(
    array('http' => array(
        'ignore_errors' => true)
    )
);

Any calls using the HTTP stream wrapper will use these settings then, e.g. you can simply do

echo file_get_contents('http://stackoverflow.com/foo/bar');

If you also want to get the response header, just do

print_r($http_response_header);

after the call. The variable is (re-)populated after each call with a http stream wrapper.

Answer 2

By default file_get_contents only returns the content of HTTP 200 responses.

With curl you get the headers and the content separately.

As of PHP 5.0, you can also specify a context for file_get_contents, allowing you to do it without relying on url (See Gordon's answer).

Answer 3

Step 1: check the return code: $content = file_get_contents("websitelink"); if($content === FALSE) { // handle error here... }

Step 2: suppress the warning by putting an error control operator (i.e. @) in front of the call to file_get_contents(): $content = @file_get_contents($site);

Answer 4

Use cURL instead. It allows much greater control, and will let you read any content retrieved and the status code.
