Dammit. I see you guys talking about the server specs, but I can't find the link to the doc. Can you throw it up again?

I'm still not 100% on what the server does. Just logs identifiers and sends them to an Apple gateway for push notifications?

I posted the relevant php like 45 minutes ago, I'm just compiling a feed of deviceTokens that I will use in a desktop app to send updates to phones.

Are you trying to remove duplicates in the $dev variable or duplicate lines in the file? If it's duplicate lines in the file, this should do it:

$lines = file($filename);
if (!in_array($front.$deviceToken.$back,$lines))
{
    //append to file code in here
}

Also, you probably want to add a newline character "\n" to the end of each token when you write it to the file.

I'll give this a try, thanks.

Ok questions.

First, can you just stick /n in the middle of a string like

$back1 = '</device>\n';

because it seems to break things.

Second I'm trying to generate a feed that looks like this

<?xml version="1.0" encoding="utf-8"?>
<root>
<device><deviceToken>c32f8b7c e8d02a51 ce296c62 d3da4cb3 84fed78d b24545db fd949a73 132f2b50</deviceToken></device>
<device><deviceToken>c32f8b7c e8d02a51 ce296c62 d3da4cb3 84fed78d b24545db fd949a73 132f2b50</deviceToken></device>
</root>

right now the php code looks like this

<?php
	$deviceTokenUF = $_GET['dev'];
	$deviceToken = substr($deviceTokenUF, 1, -1);
	
	$filename = 'tokenLog';
	$front1 = '<device>';
	$front2 = '<deviceToken>';
	$back2 = '</deviceToken>';
	$back1 = '</device>';
	// Let's make sure the file exists and is writable first.
	if (is_writable($filename)) {
	    // In our example we're opening $filename in append mode.
	    // The file pointer is at the bottom of the file hence
	    // that's where $clientMessage will go when we fwrite() it.
	    if (!$handle = fopen($filename, 'a')) {
	         echo "Cannot open file ($filename)";
	         exit;
	    }
	    // Write $clientMessage to our opened file.
	    if (fwrite($handle, $front1.$front2.$deviceToken.$back2.$back1) === FALSE) {
	        echo "Cannot write to file ($filename)";
	        exit;
	    }
	    echo "Success, wrote ($clientMessage) to file ($filename)";
	    fclose($handle);
	} else {
	    echo "The file $filename is not writable";
	}
?>

I need to integrate in the duplicate checking and change it so that instead of inserting the line at the end of the file it sticks it in one up (above the </root>.

I'm a php dummy dumb, so any help would be useful. Also bear in mind that this might eventually become a hightraffic piece of code so tight and fast is important.

Ok so here's where I am now, the line duplication doesn't seem to be detected.

<?php
	$deviceTokenUF = $_GET['dev'];
	$deviceToken = substr($deviceTokenUF, 1, -1);
	
	$filename = 'tokenLog';
	$front1 = '<device>';
	$front2 = '<deviceToken>';
	$back2 = '</deviceToken>';
	$back1 = '</device>';
	// Let's make sure the file exists and is writable first.
	if (is_writable($filename)) {
	    // In our example we're opening $filename in append mode.
	    // The file pointer is at the bottom of the file hence
	    // that's where $clientMessage will go when we fwrite() it.
	    if (!$handle = fopen($filename, 'r+')) {
	         echo "Cannot open file ($filename)";
	         exit;
	    }
		
		$lines = file($filename);
		$numElements = count($lines);
		for($i = 0; $i < $numElements - 1; $i++)
			{
				print $lines[$i];
				print '
				';
			}
		if (!in_array($front1.$front2.$deviceToken.$back2.$back1, $lines))
		{
			print 'Not In Array
			';
			for($i = 0; $i < $numElements - 1; $i++)
			{
				fwrite($handle, $lines[$i]);
			}
    		fwrite($handle, $front1.$front2.$deviceToken.$back2.$back1.'
    		');
    		fwrite($handle, $lines[$numElements - 1]);
		} else {
			print 'In Array
			';
			for($i = 0; $i < $numElements; $i++)
			{
				fwrite($handle, $lines[$i]);
			}
		}
	    
	    echo "Success, wrote ($clientMessage) to file ($filename)";
	    fclose($handle);
	} else {
	    echo "The file $filename is not writable";
	}
?>

Is there a decent PHP debugger so I can step through and see the variables I'm trying to work on. I've tried some debuggers in the past and always found them confusing.

try dreamweaver, should work with php

if you dont have it, download it. its fuckin expensive

First, create the file with no entries that starts like this:

<?xml version="1.0" encoding="utf-8"?>
<root>
</root>

Then try this:

<?php
    $deviceTokenUF = $_GET['dev'];
    $deviceToken = substr($deviceTokenUF, 1, -1);

    $filename = 'tokenLog';

    $line_to_add = "<device><devicetoken>$deviceToken</deviceToken></device>";
    
    //see if this line exists
    $lines = file($filename);
    if (!in_array($line_to_add,$lines))
    {
        //doesn't exist

        //first pop off last </root> element and add it back later
        array_pop($lines);
            
        //now add new device token line
        array_push($lines,$line_to_add);
            
        //now add </root> line
        array_push($lines,"</root>");
            
        //now combine into one string separated by newlines
         $new_lines = implode("\n",$lines);

        // Let's make sure the file exists and is writable first.
        if (is_writable($filename)) {
            if (!$handle = fopen($filename, 'w')) {
                 echo "Cannot open file ($filename)";
                 exit;
            }

            //lock the file for writing
            flock($fp, LOCK_EX);

            //write string to file
            fwrite($handle,$new_lines);

            // release the lock
            flock($fp, LOCK_UN);

            echo "Success, wrote ($clientMessage) to file ($filename)";
            fclose($handle);
        } else {
            echo "The file $filename is not writable";
        }
    }

?>
