05-31-2009, 04:33 AM
Hello. I am programming a game. When game is over the user enters his first and last name. But i have no clue how to do this. It must be done like this : user enters his first and last name and score is automatical. Im not strong in php. Php should write node with information just given and only with the score that is higher than the lowest score.

I have script that shows usernames and score points. But the main problem is that i want to write 10 top scores in xml file. The ordering is not important. Can anyone help me please?

<?xml version="1.0" ?>
<name first="James" last="Johnson" gpa="1222" />
<name first="John" last="Smith" gpa="1111" />
<name first="Serena" last="Williams" gpa="1000" />
<name first="Indiana" last="Jones" gpa="999" />
<name first="Linda" last="Brown" gpa="888" />
<name first="Robert" last="Davis" gpa="777" />
<name first="Seno" last="Cular" gpa="666" />
<name first="Mike" last="Wilson" gpa="555" />
<name first="Mary" last="Moore" gpa="444" />
<name first="Will" last="Taylor" gpa="333" />

First read the file to a string:

$xml = file_get_contents('/path/to/file.xml');

Then you can manipulate the XML using either string functions, regular expressions or PHP's xml parsers (DOM, SimpleXML etc).

I think the easiest is the DOM if you're familiar with it.

simple xml if also fairly easy to use:

You'll just need to retrieve all the "name" xml nodes and their attribute values into an array. Then sort the array with "sort" or "usort".

Make sure the new entry is higher then the lowest. Create an XML node for it and insert it into the XML Object.

Write this back to the file.

Hi. Thank You. You are very kind for answering. I have this kind of php code:

$file_handle = fopen('toplist.xml','a');
$content = '<?xml version="1.0"?>
foreach ($result as $row)
$content.="\n<name first='".$row->mark."' last='".$row->mark."' gpa='".$row->mark."' />\n";
How do i send information to php file? and how do i calculate witch is the lowest score? I have to do it fast. I have no time to learn. Maybe someone or you can help me with the code?

The flash variables are firstname lastname and score
