JavaScript get input caret cursor position; getSelectionStart getSelectionEnd; char position

To get the input field character position using JavaScript, use the following:
Javascript
 
function getSelectionStart(o) {
    if (o.createTextRange) {
        var r = document.selection.createRange().duplicate();
        r.moveEnd("character", o.value.length);
        if (r.text == "") {
            return o.value.length;
        }
        else {
            return o.value.lastIndexOf(r.text);
        }
    }
    else {
        return o.selectionStart;
    }
}
 
function getSelectionEnd(o) {
    if (o.createTextRange) {
        var r = document.selection.createRange().duplicate();
        r.moveStart("character", -o.value.length);
        return r.text.length;
    }
    else {
        return o.selectionEnd;
    }
}

PHP Recursively list directories and files; recursive listing scan and traversal

PHP
 
error_reporting(E_ALL | E_STRICT);
ini_set('display_errors', 1);
 
header('Content-Type: text/plain');
 
$dir = dirname(__FILE__);
 
foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($dir)) as $item) {
    if ($item->isFile() || $item->isDir()) {
        echo $item . PHP_EOL;
    }
}
