PHP Writing to a file help

[adammc]

Hi folks,

I am trying to create a script that will take the MYSQl DB details that have been sent from a form and store it in a file for usage at a later stage.

Am I doing this correctly?

$File = "db-settings.php"; 
$Handle = fopen($File, 'w');

$Data = "$dbuser = $_POST['dbuser'];\n"; 
fwrite($Handle, $Data); 

$Data = "$dbpass = $_POST['dbpass'];\n"; 
fwrite($Handle, $Data); 

$Data = "$db = $_POST['db'];\n"; 
fwrite($Handle, $Data); 

$Data = "$host = $_POST['host'];\n"; 
fwrite($Handle, $Data); 

print "Data Written"; 
fclose($Handle); 

Any advice would be greatly appreciated

You need to escape $dbuser and $dbpass and so forth. Otherwise you'll end up with:

= username
= password
= db
= host

see below.

$File = "db-settings.php"; 
$Handle = fopen($File, 'w');

$Data = "\$dbuser = {$_POST['dbuser']};\n"; 
fwrite($Handle, $Data); 

$Data = "\$dbpass = {$_POST['dbpass']};\n"; 
fwrite($Handle, $Data); 

$Data = "\$db = {$_POST['db']};\n"; 
fwrite($Handle, $Data); 

$Data = "\$host = {$_POST['host']};\n"; 
fwrite($Handle, $Data); 

print "Data Written"; 
fclose($Handle);

I prefer using an ini-file (not very Unix but still), protected by htaccess.
To read/write from and to ini-files I wrote a simple PHP class.
For example an ini-file would contain:

setting = value; #Comments

ZareMedia,
Thanks for the great tip

I have added this for error checking:

if(!$Handle) {
    echo 'Error, the file could not be opened or there was an error creating it.';
    exit;
} 

Should I be checking anytinhg else?

[adammc]

Is there a way to check that data was written?
