PHP File open to read internal file

WE can open a file or a URL to read by using fopen() function of PHP. While opening we can give mode of file open ( read, write.. etc ). By using fopen we can read any external url also. We can write to a file by using fwrite function. Let us start with reading one internal file ( of the same site ). We have a file name as delete.htm. We will use the command fopen() to open the file in read mode.

We will be using fread() function to read the content by using a file pointer. Fread() reads up to lengthbytes from the file pointer referenced by fd. Reading stops when length bytes have been read or EOF is reached, whichever comes first.

We have also used the function filesize() to know the size of the file and used it in the fread function.
We will be using all these functions to read the content of another file and print the content as out put. Here is the code.

<?
$filename = "delete.htm"; // This is at root of the file using this script.
$fd = fopen ($filename, "r"); // opening the file in read mode
$contents = fread ($fd, filesize($filename)); // reading the content of the file
fclose ($fd); // Closing the file pointer
echo $contents; // printing the file content of the file
?>
