read file using php
/*
In php to read file first you have to use 'fopen' method to open the file after that you perform different operation on it.
Like Reading file, Writing file etc.
TO read file data we have to use 'fread' method.
*/
<?php
$myfile = fopen("read_text_file.txt", "r") or die("Unable to open file!");
echo fread($myfile,filesize("read_text_file.txt"));
fclose($myfile);
?>
