如何使用PHP获取用户的pc时间

Question

I am working on an application in which I need to get date & time of local pc of user. Basically php have date and time functions and it returns server time as it is server side scripting language.

I am getting correct time using javascript Date function but when i use strtotime function in php it doesn't work, i need a way to get local time in php.

<script type="text/javascript">

function getDate() 
{ 
        var d = new Date();
    var c_day = d.getDate();
    var c_month = d.getMonth() + 1;
    var c_year = d.getFullYear();
    var c_hour = d.getHours(); 
    var c_min = d.getMinutes(); 
    var t = c_day+"-"+c_month+"-"+c_year+" "+c_hour+":"+c_min;
    return t;
}
if (window.XMLHttpRequest)
{
    xmlhttp=new XMLHttpRequest();
}
else
{
    xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
    if (xmlhttp.readyState==4 && xmlhttp.status==200)
    { 
        alert(xmlhttp.responseText);        
    }
}    
xmlhttp.open("GET","setdate.php?sdate="+encodeURIComponent(getDate()),false);
xmlhttp.send();
</script>

The file 'setdate.php' stores sdate value in the session and i am getting it as an output of ajax.

<?php
$sdate = $_SESSION['sdate'];
$date = date( "d/m/Y", strtotime( $sdate ) );
?>

This works after refreshing the page, but not when the page loads first time.

Any one can help me on this ?

You can not get Client Side Date using php alone.

For client side, you would need Javascript, something like the following should do the trick.

var currentTime = new Date();

You can use AJAX to send this to server.

var currentTime = new Date();
$.ajax({
    url : url,
    data : {date : currentTime}
});
