SimpleXmlElement – save indented tree
As everyone should be aware, SimpleXmlElement class is not capable to preserve the indents in xml output.
To achieve that the DOMDocument class comes in handy.
//Format XML to save indented tree rather than one line and save
$dom = new DOMDocument('1.0');
$dom->preserveWhiteSpace = false;
$dom->formatOutput = true;
$dom->loadXML($xml->asXML());
$dom->save('fileName.xml');

How to set div to center of the screen
<div id='div_id'> Blah! Blah! </div>
To set the div above to the center we can use next JQuery code.
jQuery.fn.center = function () {
var w = $(window);
this.css("position","fixed");
this.css("top",w.height()/2-this.height()/2 + "px");
this.css("left",w.width()/2-this.width()/2 + "px");
return this;
}
$("#div_id").center();

We have the html code below:
<select name="sel" id="sel"> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> <option value="4">4</option> </select>
Code below set the current value
document.getElementById("sel").value = 3
or
function setSelectedIndex(s, v) {
for ( var i = 0; i < s.options.length; i++ ) {
if ( s.options[i].value == v ) {
s.options[i].selected = true;
return;
}
}
}
To extract the selected value the code below will help
