Writing results to a file

[jamesloi]

Hi,

Does anyone know how i can write to a file using php code...? I want to be able to write data into an .xml file from php code.

many thanks

You will want to read up on these functions:
fopen()
fwrite()
fread()
fclose()

<?php
$filename = 'test.xml';
$somecontent = "<tag>Add this to the file</tag>\n";

// Let's make sure the file exists and is writable first.
if (is_writable($filename)) {

// In our example we're opening $filename in append mode.
// The file pointer is at the bottom of the file hence 
// that's where $somecontent will go when we fwrite() it.
if (!$handle = fopen($filename, 'a')) {
     print "Cannot open file ($filename)";
     exit;
}

// Write $somecontent to our opened file.
if (!fwrite($handle, $somecontent)) {
    print "Cannot write to file ($filename)";
    exit;
}

print "Success, wrote ($somecontent) to file ($filename)";

fclose($handle);

} else {
    print "The file $filename is not writable";
}
?>

Here is a link to all of PHP's filesystem functions, some of which you may find useful, which I have not mentioned above

Hi,

i am using this code

$variable_file = "order";
		$handle = fopen($variable_file.".xml" , "w"); // The "w" opens the file for writing

		$string = "hello		
	fwrite($handle, $string);

	fclose($handle);

but it gives me the error
Warning: fwrite(): supplied argument is not a valid File-Handle resource in /home/lj917/public_html/checkout2.php on line 92

Warning: fclose(): supplied argument is not a valid File-Handle resource in /home/lj917/public_html/checkout2.php on line 94

Looks as though you have a syntax error:

$string = "hello        

        fwrite($handle, $string);

//should be:
$string = "hello";
//take note of "; at the end        

        fwrite($handle, $string);

Yeh i fixed that syntax error but i am gettin these warnings

Warning: fopen("order.xml", "w") - Permission denied in /home/lj917/public_html/checkout2.php on line 84

Warning: fwrite(): supplied argument is not a valid File-Handle resource in /home/lj917/public_html/checkout2.php on line 92

Warning: fclose(): supplied argument is not a valid File-Handle resource in /home/lj917/public_html/checkout2.php on line 94

I have changed the permissions of order.xml to 755 so why is it still giving me these errors....?

[JDcrack]

If you are running the script from your browser,
ie http://domain.com/script.php

The script is being ran as:
user Nobody
Group Nobody

So permissions set at 755 are not good enough,
for testing purposes try setting permissions at 777,
see if it works, this way you know it is a permissions error, and not a syntax error.

Of course it is not safe to leave permsions set at 777.
