best function to use ~ file_get_contents or ?

Hi All,
Not sure of the best approach, need your feedback. I have 4 images on a
website. These are used in navigation. When I load a reference webpage on my
local machine the local page calls 4 images from an external website, each
image will be on a different domain.

What I want to see is if the navigation images/buttons can be loaded/displayed
in my browser. If they can, then I will display the images on my local page.
If the images cannot be loaded, then this indicates some connection issue and
the result will be some text like 'Site Offline'. So just by glancing at my
local machine reference page I can tell if one or more of the different sites
is or is not available.

So what is the best function to use?

if ( @file_get_contents( DOMAIN_PATH . "images/navigation/nav_globalissa.png" )):

or ???

Please also cc info@globalissa.com

Thanks for any helpful suggestions.

Sincerely,

Shouldn't it be:

if ( @file_get_contents( DOMAIN_PATH .
"images/navigation/nav_globalissa.png", FILE_BINARY))

There is no best function as such. Everything depends upon your requirement.

You can also use fopen() to get the contents of the remote file and do some
error handling that if you get any content then display image else a message
etc..

The way I've always seen this approached before is by using the wget
command, which can be asked to just return the headers for a page. In
your case you'd be looking for all 200 codes, which means that all the
sites are up. This is faster than asking to return a full image each
time.

but slower 'cause for each image you need to requests

On the other hand=2C file_get_contents could return false positives cause t=
he fact we are asking for an image does not mean an image will be returned.

I would go for a curl call=2C where you can have both headers and content s=
o in one call you can handle every case. A bit slower than a HEAD request=
=2C surely faster than a HEAD request plus the REQUEST.

One more thing=2C I hope you have rights to grab these images=2C usually th=
ere are APIs or webservices when a website would like to share images in th=
is way but it does not seem the case here ...

Requesting only the headers is a lot faster than requesting the headers
AND the file itself. I'd also not look to grab an image anyway, try
grabbing just the HTML of a web-page. You get the headers, and the HTML
is likely to be very small in size. Not only that, you can perform other
tests on the returned HTML, for example to see if PHP is still running
on the remote site. All of this is very easy to accomplish with a single
line call to wget.

This is what I said=2C except if you want to grab the content you need to r=
equest HEAD first and eventually GET=2C and this is slower than just GET pa=
rsing headers.
In any case=2C curl is the answer=2C imho.
