Using PHP Output Buffering Control…
There’s a function in PHP called readfile which will read a file and send its contents to stdout. That can be handy, but it’s not much good to you if you want to read the content of the file into a string.
There’s a neat trick using PHP’s output buffering that enables you to read the content of a file into a string without printing anything on stdout, and it goes like this:
// start an output buffer ob_start(); // print the file to the output buffer readfile( $file_path ); // get the contents of the output buffer $content = ob_get_contents(); // cancel the output buffer ob_end_clean();
