reading from a file and sorting it into an array

[minneapolis]

Cheers Everyone of you,

I just started using this beautiful language and i am already in pain.
I setup a php form where i can ask users to enter:
name
ssn(fake ones)
donations
email address
message

i am able to view the displayed information entered into a PHP form.
and from that form, i write it to a file using a button.
However, i want to read from that file and at the same time sort the information by SSN.
I don't know how to sort and at the same time read.
arraysort will do it.
Can anyone help please, thanks.

Post some code.

Could you not write the information to a mysql database?

It would probably work better than just writing to a file and you can apply sort to your query.

Hope this helps.

Hello all of you and Thanks for the prompt reply,

abc123, I don't think i know how because i wnat to keep it simple(assign requirements). The use of an array is required.
Here is the code that i jot down for the last php file:

<.........

<h1>Data captured:</h1><br>

<?php

//create short variable names
$name = $_POST['name'];
$ssn=$_POST['ssn'];
$email = $_POST['email'];
$subject = $_POST['subject'];
$message = $_POST['message'];


?>

<?php

//$narray[0]="name"; wrong def of my array
//$narray[1]="ssn";
//$narray[2]="email";
//$narray[3]="subject";
//$narray[4]="message";

$myFile = "testFile.txt";
$fh = fopen($myFile, 'r');
$theData = fread($fh, filesize($myFile));
fclose($fh);
echo $theData;
?>


<form method="post" action='p2.html' name="goBack">
	<input type="submit" name="view" value="GoBack">
</form>

</body>
</html>

I am kind of confused of how i can assign an array to a variable and sort the array by one of the variables.?
GOAL: when the user clicks on the display button, the data read from the file(testfile) is sorted by SSN...

Thanks for the help.

I still need some help
<?php

$err_cnt = 0; 
$read_ctr = 1; 

$lines = array(); 

@ $fp = fopen("testfile.txt", 'r');    //Open file for reading 

if ($fp) 
{ 

 while (true) 
	{ 

    $line = fgets($fp,200); 

    if (feof($fp)) 
    { 
        break; 
    } 

        $fields  = explode('*', $line); 
        $name_read = $fields[0]; 
        $ssn_read = $fields[1]; 
        $email_read = $fields[2];
    $subject_read = $fields[3];
    $message_read = $message[4];					 

    $new_line = "$ssn_read.$name_read.$email_read.$subject_read.$message_read\n"; 


        array_push($lines, $new_line); 

    $read_ctr++; 

    }
