splitting text file contents into seperate arrays.

I need help splitting the contents of a text file into an array. I tried using the split() function. However, that would not work because the file is already an array...
Each line of the text file is: name,phonenumber,email,website

I need to split each of the words between the commas into arrays. I don’t know how you would split the file contents if the contents is already in an array. For example I’ve got so far:

$selectedfile = "./courses/".$_GET['course'].".txt";
$openfile = file($selectedfile); //this works
$splitfile = split(",",$openfile); //this doesn’t. $openfile is already an array.

Also, after I get each word of each line split into an array, how would I put the array contents into an HTML table. Would it be as simple as just doing:

echo “<table>”;
foreach($arrayname as $tablearray)
{
echo “<tr><td>$tablearray</td></tr>”

}
echo “</table>”

Thanks

You can do it like this:

$selectedfile = "./courses/".$_GET['course'].".txt";
$openfile = file($selectedfile); //this works

foreach ($openfile AS $line)
{
	// name,phonenumber,email,website
	list($name, $phone, $email, $website) = explode(',', $line);

	echo "<tr><td>Name: {$name}</td></tr>\n";
	// Etc...
}

text manipulation is server intensive
