从数组中创建编号列表

Question

Here is what im using for test purposes to simplify what im asking for. What im trying to achieve is:

1. Firstnameinarray, 2. Secondnameinarray, 3. Thirdnameinarray

Right now I am getting this:

Firstnameinarray, Secondnameinarray, Thirdnameinarray

this is the code:

$list = file("pready.txt", FILE_SKIP_EMPTY_LINES | FILE_IGNORE_NEW_LINES);
        $num = 0;

        $listn = implode(", ", $list );
        $get = explode(",", $listn);

        echo "$listn";
        echo "<br>";
        echo "$get[0]"; //this is for my testing of another part of the script

Thank you in advance!

This should do the trick. I'm not aware of a native function that will do exactly what you want, so this is kind of a roundabout way to do it.

$list = file("pready.txt", FILE_SKIP_EMPTY_LINES | FILE_IGNORE_NEW_LINES);
$resultString = "";

foreach($list as $index => $entry)
{
    $resultString .= $index . ". " . $entry . ", ";
}

$resultString = substr($resultString, 0 , -2);

echo $resultString;
