// Before we receive the relevant content, the Web server will process PHP
// (Because we are simulating a Web browser in essence ),
// So we will get a static HTML page.

// Specify that we will read 1 MB of data (exceeding this data volume usually means an error ).

// Close the connection to the source "file" after the work is completed.

// Open the temporary file (created in this process at the same time) for writing (note the usage of 'W ).
