Can't write to .txt file.

arkum

Hi there.

So I recently installed/activated PHP5 and my SQL on my laptpop (macbook pro) and everything seemed to be working fine.

However, when I try to use it to write to a .txt file ( using fopen/ fwrite) I recieve the following Error:

"failed to open stream😛ermission denied"

I have tried:

1/Using relative and absolute URLs to target the file.
2/Checking PHP is not running in Safe Mode.
3/Checked permissions on the .txt file and all other folders right up to my Sites folder.
4/Slamming my hand on the desk and throwing a biro at the wall.

But I am still stuck. I've done exhaustive searches for a solution, but all the posts which mention this Error message seem to either fail to resolve it, or resolve it by changing the chmods.

Please help me.

Can u add your code, but please encapsulate your code between php tags (

...

)

Before adding your code, try this one is from php manual modified a little by me ...

<?php 
	$filename = 'test.txt'; 
	$somecontent = "Write this to the file\n"; 

   if (!$handle = fopen($filename, 'w')) { 
        print "Cannot open (create) file ($filename)"; 
        exit; 
   } else {
	   if (!fwrite($handle, $somecontent)) { 
	       print "Cannot write to file ($filename)"; 
	       exit; 
	   } else {
		   print "Success, wrote ($somecontent) to file ($filename)"; 
	   }
   }

   fclose($handle); 
?>

Hi bogu, here you go:

foreach ($_POST as $key=>$value){
     $recieved .= "$key = $value\r\n";
}

$printout = fopen("variables.txt", "w");
fwrite($printout, $recieved);
fclose($printout);

bogu

Your script seems to be OK...

And u are running all this localy?

arkum

Yes.

Any ideas?

arkum

Just tried your code and got the same result. The full Error is as follows:

Warning:fopen(test.txt)[function.fopen]:failed to open stream😛ermission denied in /Users/myUserName/Sites/test.php on line 10 Cannot open (create) file (test.txt)

Thanks for helping.

bogu

As the error said, u dont have permision to create file, so is not about script ...

arkum

How do I give myself permission?

bogu

Didn't u restrict your access from your web server?

Houdini

I have seen this used for file permission, it is done before using fopen().

umask(0777);//add before using fopen in your script.
foreach ($_POST as $key=>$value){
     $recieved .= "$key = $value\r\n";
}

$printout = fopen("variables.txt", "w");
fwrite($printout, $recieved);
fclose($printout);

arkum

I haven't restricted my own access at all unless I did it accidentally somehow. How would I check?

Thanks for the code Houdini, but I think I need to sort this out rather than find a workaround.

Houdini

It is not a workaround what it does is sets the permission first then the fopen() should work with the file. Would you consider it a workaround to use session_start() before calling lets say $_SESSION['somevariable'] = $somevariable? No because it is required or the assignment will fail.

arkum

Sorry Houdini, but I am very new to PHP. Surely there is some way I can change permissions globally so that writing to/from all/any file is not an issue.

arkum

Tried using unmask and I get:

Fatal Error: call to undefined function unmask();

Houdini

it is umask() not unmask/B

arkum

Sorry about that.

Now I'm getting the original error message and:

Notice:Undefined variable: recieved in /Users/myUsername/Sites/etc /vartest.php on line 10

Warning: fclose():supplied argument is not a valid stream resource in /Users/myUsername/Sites/etc /vartest.php on line 11

This is because in foreach u try to concat a string to $recieved and u didnt declare it first.

This is because u couldnt open the file but u close it, u should call this function only if fopen return true ...

arkum

Ok, but that still doesn't solve the permissions problem.

bogu

No, it has nothing to do with the permission problem, I have never encounter a permission problem on a local computer, this occur only on hostings, what OS do u have?

arkum

Thanks for getting back to me bogo.

Intel macbook pro with OSX. Tried changing folder permissions all over the place to group aswell as user, but still no good.

Just out of interest, how should my code have read in relation to the undeclared var?
