File Write issues...

[TutorMe]

I have a code that I use to write a php file.  It is below.

 

<?php
$myFile = "test2.php";
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = "<?php
define('CONTIN', '1');
define('THEME', 'NullByt3');
define('TITLE','Test Null Byt3 Site');
define('FORUM_NAME', 'forums');
define('LOGOUT_TEXT', 'Log Out');
define('LOGIN_TEXT', 'Log In');
define('PROFILE_TEXT','Profile');
$db_user = 'g5gbocom_admin';
$db_host = 'localhost';
$db_pwd = '(Computer)';
$db_name = 'g5gbocom_null';
$db_prefix = 'xfrm_';
session_start();
?>";
fwrite($fh, $stringData);
fclose($fh);
?>

 

It works pretty well, exept for the last part of the file it's supposed to write.  Instead of looking like this:

 

<?php
define('CONTIN', '1');
define('THEME', 'NullByt3');
define('TITLE','Test Null Byt3 Site');
define('FORUM_NAME', 'forums');
define('LOGOUT_TEXT', 'Log Out');
define('LOGIN_TEXT', 'Log In');
define('PROFILE_TEXT','Profile');
$db_user = 'g5gbocom_admin';
$db_host = 'localhost';
$db_pwd = '(Computer)';
$db_name = 'g5gbocom_null';
$db_prefix = 'xfrm_';
session_start();
?>";

 

It writes the file like this:

<?php
define('CONTIN', '1');
define('THEME', 'NullByt3');
define('TITLE','Test Null Byt3 Site');
define('FORUM_NAME', 'forums');
define('LOGOUT_TEXT', 'Log Out');
define('LOGIN_TEXT', 'Log In');
define('PROFILE_TEXT','Profile');
= 'g5gbocom_admin';
= 'localhost';
= '(Computer)';
= 'g5gbocom_null';
= 'xfrm_';
session_start();
?>";

 

I'm sorry if this is confusing.  I'd appreciate any help.

because you're using double quotes, PHP is trying to interpolate those variable names as actual variables, which have no value and thus turn up blank in the string.  escape the $ with a backslash in order to tell PHP that you mean a literal dollar sign, not a variable indicator.

Swap all your speechmarks for single quotes AND single quotes for speechmarks

 

OR

 

Whever you have a variable in the string, break out of the string using this for example:

 

".$variablename."

".$variablename."

still won't help, as that will still attempt to interpolate the variable name as a variable, rather than simply as a string.

Oops, my bad!  :-X

Thanks to both of you, but akitchin's fix was what worked.  I appreciate the quick response.

I appologize for asking for more help so soon, but I'm stuck.

 

If I wanted to use the same script, but instead of:

define('TITLE','Test Null Byt3 Site');

use something like:

define('TITLE',$_REQUEST["title"]);

to write file data, how would I do that?  When I tried this code, it wouldn't even write the file.

 

Basically I have a form that a user fills out, and in the action, is the file with this code in it.  Any ideas?

[akitchin]

you'd write it the same way you do the other variables, except you'd need to escape the offending characters:

 

define('TITLE', \$_REQUEST['title'])

 

you're supposed to use single quotes to designate a string key of an array anyway.

[TutorMe]

you'd write it the same way you do the other variables, except you'd need to escape the offending characters:

 

define('TITLE', \$_REQUEST['title'])

 

Wouldn't this skip the "$REQUEST" part of the code?  That is code that I actually want to execute.

[akitchin]

ah, i figured you meant when the configuration script runs you need it to contain the title.  this is just a matter of interpolating the variable - you can enclose arrays in braces to have it evaluate as such:

 

define('TITLE', '{$_REQUEST['title']}')

 

you'll need to be careful about the variable's treatment of quotes in this.

Thanks sooo much.  That fixed it perfectly.

 

I really appreciate your quick response.  That is what helps make this site great.
