And what have you tried so far? We don't do free work here, this is a help board.

Does this have to be a physical file? Have you worked with MySQL before? Perhaps a database may also be an option for you?

Such a file might store connection details to a database, and you could achieve such output using var_export()

you might do something like:

PHP Code:


		
			
//



//build from user supplied input - remember to sanitise first!!!!!



$config = array(

     'username'=>'username',

     'password'=>'password',

     'host'=>'localhost',

     'dbname'=>'mydatabase'

);



//build string using var_export



$c = '<?php $config = '.var_export($config,1).";";



//write to file



file_put_contents("config.inc.php",$c);

which would write

Code:

<?php $config = array(
     'username'=>'username',
     'password'=>'password',
     'host'=>'localhost',
     'dbname'=>'mydatabase'
);

to the file "config.inc.php"

some other code would then include config.inc.php and $config would be available as expected

Also consider alternative file formats like JSON or XML. Both are very easy to read and write.

But for a php application I would always recommend storing such data as raw php - it will execute an awful lot quicker as there is no overhead in decoding the data (XML or json).

The caveat is always security and making sure that executable code which does something is not stored. So validate your data for type and sanitise for use.
