Question

file_get_contents($file) function must be executed in order to get html encoded file after that.

Function crashes returning

failed to open stream: Invalid argument

However, if I set a text string (containing path) instead of variable call, it works. If I check variable content seems that is properly set before crashing.

Answer 1

$filePath = '/complete/path/to/file.html';
if(is_file($filePath))
{
  $fileContents = file_get_contents($filePath);
  echo $fileContents; // echo out file contents
}
