Using URLs as file names in PHP
PHP can use URLs as file names for reading and writing
Reading from a URL connects to a remote resource and downloads its contents
Downloaded contents may be HTML, XML, or JSON data
Writing to a URL can post data to a web page and receive a response
Example: downloading a webpage from http://cse.unl.edu
Open the webpage URL for reading with fopen
Initialize an empty string to store the downloaded contents
Read and append lines until the end of the file is reached
Alternatively, download the complete webpage with file_get_contents

"44.2.1. Using URLs A nice feature of PHP is that you can use URLs as file names to read and write to a URL. “Reading” from a URL mean connecting to a remote resource, such as a webservice and downloading its contents (which may be HTML, XML or JSON data). Writing to a URL may be used to post data to a web page in order to receive a response. As an example, we can download a webpage in PHP as follows.\n\n1 $h = fopen(\"http://cse.unl.edu\", \"r\");\n\n2 $contents = \"\";\n\n3 while(!feof($h)) {\n\n4 $contents .= fgets($h);\n\n5 }\n\n6\n\n7 //or just:\n\n8 $contents = file_get_contents(\"http://cse.unl.edu\");"
