How to update a text file using fopen functions...

To Whom It May Concern

Using fopen(), fsockopen(), fputs(), fclose() how to update a sample text file which is already residing in the Apache server.

I'm working in an exchange server ( both Internet and Intranet ) and I have my apache installed, I want to test the files locally.

So, I have uploaded my php3 file and a sample text file.

<?php
$fp = fopen ("http://valinux-system/raj/sample.txt", "r+");
if ($fp)
{
print "The file exists";
$str = "there";
fwrite ($fp, $str);
echo "$str";
}
else
{
print "The file does not exist";
}
?>

The keyword 'there' is not getting updated on to the sample.txt file.

What could be wrong??? I would be glad if you illustrate me with examples.

Please help me out!!!

With Thanks & Regards,
Raj.

The "r+" statement never worked for me...
🙁

To check the file do something like a
if(file_exists("filename")){
fopen("filename", "a");

and then write to the file....

Hope that helped,

Works fine for me. If you really wanted to append you want to seek to the end of the file first.

It's never going to work if you use http to get the file!
If the file is <i>local</i> then don't use http, just open
it using the absolute (or relative) path. If it's remote,
you won't be able to update it via http.

Also, Ken is absolutely right about "r+". When you first
open the file, the current position is at the beginning
of the file; so if the write had succeeded it would have
overwritten the beginning of the file.
