fwrite(): supplied argument is not a valid File-Handle resource

[webmeister]

Hmmmm..... maybe I am drinking too much 😃 but I don't see why this would happen... $fp=fopen("filename","w") succeeds... but fwrite($fp,"content") fails with "fwrite(): supplied argument is not a valid File-Handle resource..." if a write is not permitted then shouldn't it fail on fopen() and never get to fwrite()?

code is:

$filename = $dir . "filename.txt";
$content="testing";
if (! $fp = fopen($filename,"w")) { die("Couldn't open page for writing...<br>"); }
else {
echo $fp . "<br>";
fwrite($fp,$content);
fclose($fp);
}

Do you want to REPLACE the contents of the file or just modify them?

Hi,

I got the same message and I was trying to debug this problem.

Originally, if I opened a file, I used the following code:

$fp = ($filename, "w+") || die ("Could not open file!");

This will produce the error as mentioned in this thread.

I just took out the die statement and it works:

$fp = ($filename, "w+");

you should probably code an if and else statement to capture the open error. Hope this helps!
