POST_VARS & fwrite

[Anon]

Hi, I posted some vars from a form to following code which rewrites my entire .php file. Problem is that is also removes the PHP tags <? ?> and I can no longer read the vars in config.php back into the form.
Is there a way to keep the <? ?> and to write only some of the vars.
$fp, "\$$MyEmail=\"$MyEmail\";\n" );
$fp, "\$$Myaddr=\"$Myaddr\";\n" );

/ rewrites to the entire file /
$fp = @fopen ( "config.php", "w" );
while ( list ( $varname, $varvalue ) = each ( $HTTP_POST_VARS ) )
{
fwrite ( $fp, "\$$varname=\"$varvalue\";\n" );
}
fclose ( $fp );

Thanks !

the code-sample is too short, what are you doing to read the file in the first place?

I actually wasn't trying to read the file but see what you mean.

So I've just tried this code without success, it removed the opening php tag"<?" and writes <$[e-mail]=""; to the top of the file:

$fp=fopen("config.php","r+");
fseek($fp,$StorePhone);
$content=fread($fp,filesize("$filename"));
fwrite ( $fp, "\$$MyEmail=\"$MyEmail\";\n" );
fclose($fp);
