Re: [PHP] best function to use ~ file_get_contents or ?
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..

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.

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, file_get_contents could return false positives cause the fact we are asking for an image does not mean an image will be returned. I would go for a curl call, where you can have both headers and content so in one call you can handle every case. A bit slower than a HEAD request, surely faster than a HEAD request plus the REQUEST. One more thing, I hope you have rights to grab these images, usually there are APIs or webservices when a website would like to share images in this way but it does not seem the case here ...

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.

RE: [PHP] best function to use ~ file_get_contents or ?
This is what I said, except if you want to grab the content you need to request HEAD first and eventually GET, and this is slower than just GET parsing headers. In any case, curl is the answer, imho.

[PHP] 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'.
