Reading a file into a string in PHP

If you'd like to get the entire content of a file into a string then follow the way

// have your filename with path
$file_name = "yourfilename.ext";   
$content_string = file_get_contents($file_name);
echo $content_string;   // will display the content

want to display total chars in the file?

echo strlen($content_string);

To read file into array.

// have your filename with path
$file_name = "yourfilename.ext";  
$content = file($filename);         
foreach($content as $content_row) 
  echo $content_row;
