Getting HTML Content as a variable

Hi, I've been directed to use file() or implode() to get the html content of a web page, like this: $html = implode ('', file ('http://192.168.1.100/PHP/index.php')); 1 ) How do I pass authentication to websites that require username & password? In Cold Fusion the CFHTTP tag allows you to pass USERNAME="myusername" PASSWORD="mypassword", there must be an equivalent parameter in PHP. 2) When I output the content of $html, which is the web page stored as a variable, the images are not there. Again, in Cold Fusion the CFHTTP tag takes care of this when you specify RESOLVEURL="YES", and I'm guessing there is a way in PHP to store the web page WITH images intact? thanks! ph_Greg
