How do I save a file read by curl ?

habbardone

Hi,

Simple Question ...

After I have used curl to get a file, I end up with
a variable $page_html which I can echo to display the page.

$page_html =  cURL("http://www.example.com,null,$cookie,null);

echo  "$page_html";

How would I now write this info to a file that I can later
display on screen ?

I guess it needs to be a binary file.

And is this a "snapshot" ?

I mean if the page I am viewing is showing images to other websites,
and those images later change, will my saved file display how it was with the images or with missing images ?

Do I need to save it as a pdf file ?

Thanks.

I guess it needs to be a binary file.

All files are 'binary' in some sense -- meaning that they are encoded using zeroes and ones.

My guess is that if you use cURL to grab a response from a remote webserver, that it's probably going to be HTML that you get back. This will be text and will not contain images. The HTML might refer to fully qualified urls for its images (e.g. http://example.com/image.jpg) or it might use a local file reference (e.g., /image.jpg) in which case your browser determines a baseref for the html document and evaluates all relative image references in relation to that baseref. Baserefs by default are determined by the URL of the page requested (http://example.com in your example) but can be altered in the HTML using the BASE tag:

<BASE href="http://www.example.com/index.html">

In either case, your cURL request is not going to fetch the images when it fetches the primary URL. You'll have to fetch those yourself.

Do I need to save it as a pdf file ?

I don't know. Do you?
