How do I read and write to file?

[IChaps]

Hello.

 

I'd just like to enquire how I would read and write to a file using php please?

I'm looking to write a database's, Host, Username, Password, and database Name to a file name on the server, then at a later date. When I load the site, read this information back.

 

 

At present I'm using the following to write to the file:-

// Write to file.
$fp = fopen( dirname(__FILE__).'/dbinfo.txt', 'w' ) or die("Couldn't open file:- ");
fwrite($fp, $hostname);
fwrite($fp, $database);
fwrite($fp, $username);
fwrite($fp, $password);
fclose( $fp );

 

and to read back:-

 

$fp = fopen( dirname(__FILE__).'/dbinfo.txt', 'r' ) or die("Couldn't open file:- ");
$db_host = fread($fp, $hostname); // $db_host
$db_user = fread($fp, $username); // $db_user
$db_pass = fread($fp, $password); // $db_pass
$db_databasename = fread($fp, $database);
fclose( $fp );

 

However, it reads it all in one long string, instead of it been on separate lines.

 

Would anyone know the correct way of writing this code, please?

 

Thank You.

You have to specifically write line breaks in the file. If you don't put a line break there, there won't be a line break.

fwrite($fp, $hostname . "\n");
