How to receive HTTP cookies from a web server in PHP?

Question 1

Question 2

I'm assuming that you want to interact with cookies from a remote webserver using PHP, rather than simply manipulating cookies from a client browser.

In that case, take a look at the Zend_Http and related classes in the Zend Framework. These let you perform HTTP requests with cookie persistence and a whole lot more besides.

Question 3

Try using setcookie with a a path specified, this used to catch me out, as it assumes the current path by default. Using / will make the cookie work for the whole domain

setcookie("Username", $username, time()+3600*24*30, '/');

Question 4

<?php
$cookie_name = "test";
$cookie_value = "123";
setcookie($cookie_name, $cookie_value, time() + (86400 * 30), "/"); // 86400 = 1 day
?>

You need to write your php code like this

You can use this script If u can want particular cookie

<script>
function getCookie(cname) {
    var name = cname + "=";
    var ca = document.cookie.split(';');
    for(var i=0; i<ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') c = c.substring(1);
        if (c.indexOf(name) == 0) return c.substring(name.length,c.length);
    }
    return "";
}

console.log(getCookie('test'));
<script>

Question 5

Try this one it's Working code (Swift 4).

func NKPlaceholderImage(image:UIImage?, imageView:UIImageView?,imgUrl:String,compate:@escaping (UIImage?) -> Void){

    if image != nil && imageView != nil {
        imageView!.image = image!
    }

    var urlcatch = imgUrl.replacingOccurrences(of: "/", with: "#")
    let documentpath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0]
    urlcatch = documentpath + "/" + "(urlcatch)"

    let image = UIImage(contentsOfFile:urlcatch)
    if image != nil && imageView != nil
    {
        imageView!.image = image!
        compate(image)

    }else{

        if let url = URL(string: imgUrl){

            DispatchQueue.global(qos: .background).async {
                () -> Void in
                let imgdata = NSData(contentsOf: url)
                DispatchQueue.main.async {
                    () -> Void in
                    imgdata?.write(toFile: urlcatch, atomically: true)
                    let image = UIImage(contentsOfFile:urlcatch)
                    compate(image)
                    if image != nil  {
                        if imageView != nil  {
                            imageView!.image = image!
                        }
                    }
                }
            }
        }
    }
}

Use Like this :

// Here imgPicture = your imageView and UIImage(named: "placeholder") is Display image brfore download actual image.  
imgPicture.image = nil 
NKPlaceholderImage(image: UIImage(named: "placeholder"), imageView: imgPicture, imgUrl: "Put Here your server image Url Sting") { (image) in }

Question 6

You can pass arrays as parameters to str_replace(). Check the manual.

// Provides: You should eat pizza, beer, and ice cream every day
$phrase  = "You should eat fruits, vegetables, and fiber every day.";
$healthy = ["fruits", "vegetables", "fiber"];
$yummy   = ["pizza", "beer", "ice cream"];

$newPhrase = str_replace($healthy, $yummy, $phrase);
