write variables string to another file

[echoCarlos]

Hi guys, I have a php file called install.php and the user submits there host details, the thing is i also want to write those details to these define functions in includes/config.php with the content

 

define('DB_HOST', 'change1');
define('DB_USER', 'change2');
define('DB_PASS', 'change3');

 

and overwrite change1 with host and user and pass

 

how could this be done

 

thanks

you could use file write functions to achieve this, and rewrite the config.php file when the user submits the form.

if you have the 'blank' file saved already, use the file object to read the file into a variable, and use str_replace() to change it.

$filetext = str_replace('change1','localhost',$filetext);

 

assume i have read the file contents of the example you gave, into $filetext, I then ask it to look for 'change1' in that string and replace that with 'localhost', and pass it back to the $filetext. i would then write that variable to the file and save file .

Thanks for the help but i managed to find something which did the trick on Google will post here incase anyone needs it.

 

<?php



$string = '<?php 

$dbhost = "'. $_POST["dbhost"]. '";

$dbuname = "'. $_POST["dbuname"]. '";

$dbpass = "'. $_POST["dbpass"]. '";

$dbname = "'. $_POST["dbname"]. '";

$prefix = "'. $_POST["prefix"]. '";

$user_prefix = "'. $_POST["user_prefix"]. '";

$dbtype = "'. $_POST["dbtype"]. '";

?>';



$fp = fopen("config.php", "w");

fwrite($fp, $string);

fclose($fp);



?>
