[function.file-get-contents]: failed to open stream: Invalid argument
<p>I have tried the solution for this problem and 
for this</p>

<pre><code>Warning: fopen() [function.fopen]: Filename cannot be empty
</code></pre>

<p>and for this also</p>

<pre><code>Warning: fclose() expects parameter 1 to be resource, 
</code></pre>

<p>Like Backslash and forward slash problem</p>

<p>But still facing problem
Please help me..
I am trying to change content of file on server with my file..</p>

<pre><code>$frserver =  file_get_contents("http:\\ip is here\\cdr\\settings.txt");
</code></pre>

<p>(i have tried with single slash and forward slash also) but same issue..
AFter getting this file, i cut a character</p>

<pre><code>$result = substr($frserver, 12, 1);
</code></pre>

<p>which returns me a integer value</p>

<p>Now I do same procedure with my local computer</p>

<pre><code>$frlocal =  file_get_contents("c:\\settings.txt", "r");
$result1 = substr($frlocal, 12, 1);
</code></pre>

<p>Now comparing both characters..if same no issue if not same...write in server file with my local file content.</p>

<pre><code>if($result == $result1){
    echo "No file to Update";
}
else{
$fh = fopen( $frserver, "w" );
fwrite( $fh, $frlocal );
    fclose( $fh );
    echo "file updated";
</code></pre>

<p>}</p>

<p>please have a look.</p>
