[Resolved] fread & fwrite.....

[bpat1434]

Hey guys. I'm working on an install script and kinda following what php.net funtion says. Here's what I have:

$fp = fopen('config.php', "r+");
		if(!$fp){
			echo 'Config.php is not writeable.  Please CHMOD it to 0777.<br>'.
				'<a href="'.$self.'?step=1">Go back And Try again!!</a>';
		}
		else{
			$filename = "config.php";
			$contents = fread($fp, filesize($filename));
			fclose($fp);
// Extra code I took out....
$fa = fopen($filename, "w+");
			fwrite($fa, $contents);
			fclose($fa);
			echo 'Config.php has been successfully updated.  Let us proceed tothe next step...<br>'.
				'<a href="'.$self.'?step=4">Continue ==></a>';

Basically, what I want to do is to read from config.php and extract its contents:
fread($fp, "config.php");

Then in the missing code I replace what I need, and then I want to write it back to the config.php file through fwrite...
fwrite($fa, $contents);

Unfortunately this doesn't work. It says that it has updated properly, but when I download the config.php file, nothing is changed. I'm think it's because I can't read the file, so the contents are null, and that voids the funciton. Not sure what's going on here. Any help would be appreciated.

I have narrowed it down a bit:
Upon calling back the value of $contents, it shows only the end of the document. It's not retaining all of the document. It's fairly large, but I don't know what's going on.

Thanks.

it sounds like the problem is with the part of your code you did not post.

either that, or your working on a config.php file in a different direcotry than you think.

ps-
to read the contents of a file into a string, take a look at file_get_contents()

its easier and faster.

also, when writing to the file, you dont need w+ mode unless you also want to read from it at the same time. so you could just use 'w'

take a look at the manual for fopen(), theres a chart describing what the diff modes do.

I would just use file_get/put_contents and make sure you use the full path name.

$file = 'C:/web/folder/config.php';

if (($contents = file_get_contents($file)) === false) {
    print('Could not GET the file contents.');
} else {
    // Make changes to $contents
    if (file_put_contents($file, $contents) === false) {
        print('Could not PUT the file contents');
    } else {
        print('File has been updated.');
    }
}

And if your using PHP 4 you'll need to get the file_put_contents function from my other post. Questions, let me know.

Okay guys. So I have it writing to the file... thanks for the help. Although I am getting the file written to, it's not doing as I want..... what a shock.

I pull all the information from the file, and then I want to search it for strings and replace it as it goes. Here's what I have for that function:

Well, that's what I had. After further looking on php.net I found that I should be able to do it through a loop using str_replace. Now I get some funky junk goin on with my file when it gets written. Variables come out of nowhere and are sporadically thrown throughout the entire thing. Weird.

Here's the funciton I have:

$site_name = $_REQUEST['site_name'];
			$site_url = $_REQUEST['site_url'];
			$allowreg = $_REQUEST['allowreg'];
			$db_name = $_REQUEST['db_name'];
			$db_user = $_REQUEST['db_user'];
			$db_pass = $_REQUEST['db_pass'];
			$db_host = $_REQUEST['db_host'];
			$sendmethod = $_REQUEST['sendmethod'];
			$socketfrom = $_REQUEST['socketfrom'];
			$namefrom = $_REQUEST['namefrom'];
			$sockethost = $_REQUEST['sockethost'];
			$smtpauth = $_REQUEST['smtpauth'];
			$smtpauthuser = $_REQUEST['smtpauthuser'];
			$smtpauthpass = $_REQUEST['smtpauthpass'];
			$emailclose = $_REQUEST['emailclose'];
			$emailuser = $_REQUEST['emailuser'];
			$dformat = $_REQUEST['dformat'];
			$dformatemail = $_REQUEST['dformatemail'];
			$allowattachments = $_REQUEST['allowattachments'];
			$maxfilesize = $_REQUEST['maxfilesize'];
			$uploadpath = $_REQUEST['uploadpath'];
			$ticket_display = $_REQUEST['ticketdisplay'];

		$replace = array(
			"$sitename = 'PHP Support Tickets'"=>"$sitename = '".$site_name."'", 
			"$siteurl  = 'http://www.phpsupporttickets.com'"=>"$siteurl  = '".$site_url."'", 
			"$allowreg = 'ON'"=>"$allowreg = '".$allowreg."'", 
			"$host = 'localhost'"=>"$host = '".$db_host."'", 
			"$user = 'root'"=>"$user = '".$db_user."'", 
			"$pass = ''"=>"$pass = '".$db_pass."'", 
			"$data = 'support_tickets'"=>"$data = '".$db_name."'", 
			"$sendmethod	= 'smtp'"=>"$sendmethod	= '".$sendmethod."'", 
			"$socketfrom	= '[e-mail]'"=>"$socketfrom	= '".$socketfrom."'",
			"$socketfromname	= 'From Name'"=>"$socketfromname	= '".$namefrom."'", 
			"$sockethost	= 'smtp server'", "$sockethost	= '".$sockethost."'", 
			"$smtpauth	= 'FALSE'", "$smtpauth = '".$smtpauth."'", 
			"$smtpauthuser	= 'USER'", "$smtpauthuser	= '".$smtpauthuser."'", 
			"$smtpauthpass	= 'PASSWORD'", "$smtpauthpass	= '".$smtpauthpass."'", 
			"$emailclose = 'TRUE'", "$emailclose = '".$emailclose."'", 
			"$emailuser  = 'TRUE'", "$emailuser  = '".$emailuser."'", 
			"$dformat	= 'd-m-Y'", "$dformat	= '".$dformat."'", 
			"$allowattachments = 'TRUE'", "$allowattachments = '".$allowattachments."'", 
			"$maxfilesize	  = '10240000'", "$maxfilesize	  = '".$maxfilesize."'", 
			"'/FOLDER/upload/'", "'/".$uploadpath."'", 
			"$ticket_display = '50'", "$ticket_display = '".$ticket_display."'");

		foreach($replace as $key=>$value){
			$contents = str_replace($key, $value, $contents);
		}

I'm gonna keep workin on it, and hopefully get it working.

I really think I'll have to go back to the eregi_replace() for each line that I want replaced. Or perhaps I should just edit my loop to only search teh document for the exact match as I think similar matches are being returned....

Help would be greatly appreciated.

I'm just an idiot

Thanks for the help guys in getting the file writing to work. Really helped. If you look at the code I posted, you'll see my n00bish mistake.... oh well... it's 3 am here. So I fixed it and it's working like a charm now....

Thanks again for the help.
