Another Problem

Jul 22nd, 2008

I can't seem to get the fopen thing to work, or otherwise, I'm just stupid if it is but I don't know it.

Here is the code:

 Help with Code Tags 
 php Syntax (Toggle Plain Text) 
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<HEAD>
<title>Open the file</title>
</HEAD>
 
<body>
 
<?php
 
$fp = fopen("http://www.mydomain.org/order.txt", "a+");
fclose($fp);
 
?>
 
</body>
 
</html>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<HEAD>
<title>Open the file</title>
</HEAD>

<body>
 
<?php

$fp = fopen("http://www.mydomain.org/order.txt", "a+");
fclose($fp);

?>

</body>

</html>

If that should work, how would I be able to tell, or should I add something to see if it works.

Thanks

Alright, your idea (buddylee) worked, by telling me that the file did not open, but how can I get the file to open? This is the big problem that I have been having.

Do you have access to the server? Your host may have the functions disabled. If you are not sure, place the following into a new php file and name it phpinfo.php:

 Help with Code Tags 
 php Syntax (Toggle Plain Text) 
<?php
phpinfo();
?>
<?php
phpinfo();
?>

This page will output all of apaches settings. What you should look for is under PHP Core. The directive is named disable_functions. If fopen is disabled, it will be listed here. Just a thought.

Do you mean this?

Directive Local Value Master Value
allow_url_fopen On On

Or this one:

disable_functions no value no value

And since I own that website, and since I can save other files to that folder, I'm pretty sure that I have access, or does it have to do with the folder permissions thing? The permissions code for the folder that I want to open the file in is "drwxr-xr-x".

Would you want to see the actual phpinfo file?

No, it was just a hunch. Can you test a local file? Create a text file, type a couple of words in it to give it some testable content and save it as testFile.txt in the same directory as your current script. Now run the following:

 Help with Code Tags 
 php Syntax (Toggle Plain Text) 
<?php
$file="testFile.txt";
$fp = fopen($file, "a+");
if($fp){
echo "file opened ";
}
else{
echo "file did not open ";
}
if(filesize($file)!=0)
	{
	$contents = fread($fp, filesize($file));
	echo $contents;
	}
	else
	{
	echo "The file is empty";
	}
	fclose($fp);
?>
<?php
$file="testFile.txt";
$fp = fopen($file, "a+");
if($fp){
echo "file opened ";
}
else{
echo "file did not open ";
}
if(filesize($file)!=0)
	{
	$contents = fread($fp, filesize($file));
	echo $contents;
	}
	else
	{
	echo "The file is empty";
	}
	fclose($fp);
?>

Note that the script checks filesize before attempting fread. You'll get an error attempting fread if the file is 0.

I believe you can only use a write mode such as 'a+' with fopen on a remote file if using ftp:// as the protocol...even so, you would have to have appropriate ftp permissions to write/append. More about that here:

It worked, and inside the text file I put in the words Hi, and this is what was outputted:

file opened Hi

So opening files work if it's already there, but I can't create new ones for some reason
