I want to create a cookie using php,an also i need to read it using javascript.ie, by using setcookie('mycookie','hello',time()+34000) in php i am creating a cookie in my system.Now,i need to read it using javascript.Is it possible?If anybody knows please give me some idea.Please....help me.I am using javscript as follows `

function Get_Cookie( check_name ) { // first we'll split this cookie up into name/value pairs // note: document.cookie only returns name=value, not the other components var a_all_cookies = document.cookie.split( ';' ); var a_temp_cookie = ''; var cookie_name = ''; var cookie_value = ''; var b_cookie_found = false; // set boolean t/f default f

for ( i = 0; i < a_all_cookies.length; i++ )
{
    // now we'll split apart each name=value pair
    a_temp_cookie = a_all_cookies[i].split( '=' );


    // and trim left/right whitespace while we're at it
    cookie_name = a_temp_cookie[0].replace(/^\s+|\s+$/g, '');

    // if the extracted name matches passed check_name
    if ( cookie_name == check_name )
    {
        b_cookie_found = true;
        // we need to handle case where cookie has no value but exists (no = sign, that is):
        if ( a_temp_cookie.length > 1 )
        {
            cookie_value = unescape( a_temp_cookie[1].replace(/^\s+|\s+$/g, '') );
        }
        // note that in cases where cookie is initialized but no value, null is returned
        return cookie_value;
        break;
    }
    a_temp_cookie = null;
    cookie_name = '';
}
if ( !b_cookie_found )
{
    return null;
}

} if (Get_Cookie('__gsb')) { alert('Found'); } `
