Answered: What are the different types of PHP variables?

Fri, 29 Oct 2021 10:06:08 +0000

There are 8 data types in PHP which are used to construct the variables:

Integers − are whole numbers, without a decimal point, like 4195.
Doubles − are floating-point numbers, like 3.14159 or 49.1.
Booleans − have only two possible values either true or false.
NULL − is a special type that only has one value: NULL.
Strings − are sequences of characters, like ‘PHP supports string operations.’
Arrays − are named and indexed collections of other values.
Objects − are instances of programmer-defined classes, which can package up both other kinds of values and functions that are specific to the class.
Resources − are special variables that hold references to resources external to PHP.

Answered: Google ReCaptcha is active but not preventing spam

Wed, 02 Jun 2021 11:32:46 +0000

You can add a honeypot on you form. A honeypot is a field added to the form that the users can’t see due to CSS or JavaScript (which hides the field). When a spam bot comes to a form, it fills out EVERY input field, but it ignores the CSS code. This is the behavior we can exploit. You would create a regular form input field with HTML (this will be the honeypot field). The spam bot will see the field, but you’ll use JavaScript to hide the field from users. If the honeypot field is empty, the Javascript code would submit the form. On the other hand, if the honeypot field has data, you know it could only have been filled out by a spam bot.

Answered: Why no site links listed on google search?

Fri, 13 Dec 2019 03:49:05 +0000

Google does not show sitelinks for all websites. The fact that it may decide to show sitelinks when users search for your domain name or for particular queries, it’s a signal of google trust.

You cannot directly specify which pages Google should use as sitelinks. They are chosen automatically by the Google algorithm based on the user query.

Answered: Scan QR code using a samsung phone

Thu, 14 Nov 2019 06:25:03 +0000

You can do it using Bixby Vision on your phone (if its after the s7 series)

OR

If your Galaxy device doesn't support Bixby Vision, you are still able to scan QR Codes however this will be directly through Samsung Internet or Samsung Internet (Beta). Usually the Samsung Internet application is pre-installed on later Galaxy devices however if you have uninstalled this app or you are unable to locate this app within your apps tray, you can easily download it from the Google PlayStore.

Samsung Internet makes separate QR code reader apps totally irrelevant. Samsung's browser includes a QR code reader directly in-app, which makes scanning website QR codes a breeze. Just enable "QR code reader" in the Extensions menu, then tap the three dots to access "Scan QR Code" at any time.

You will need to enable the QR code scanner from the extensions of the internet browser.

Answered: Mailchimp automatic feed mailing with custom design

Wed, 13 Nov 2019 06:40:52 +0000

Solution for your issue is to make a custom feed with the whole HTML needed for your newsletter and pass it as a feed to the mailchimp. Note that the mailchimp processor will strip the html tags if not instructed not to do so. Passing contents through feed within a CDATA tag would do the trick, which will bypass the mailchimp processor. See below example data that should be passed in the description section of a feed.

Answered: Strange “1” displayed at the end of a php print_r ?

Mon, 19 Nov 2018 22:29:07 +0000

Remove the echo before print_r

the print_r is supposed to return true/false which is displayed as 1 with the echo.

So you only need the following.

        echo '<pre>'
        print_r($validation->getErrorFields());
        echo '</pre>'

All older pages should be caught under this rule.

Answered: What is difference between abstract class and interface classes?

Tue, 02 Jan 2018 04:28:23 +0000

Google and you will find it. This is not a question to answer, but to learn yourself as all others do.

Interface : An interface does not contain any code,it contain only declaration of    methods,properties,events. Interfaces allow us to code which specifies which methods a class must have implement . Interfaces defines with the word interface . All methods in interfaces must be public
   e.g :     interface myItem

                    {

                        void Id();
                       string description();
string Runtest(int testnumber);

                    }

Abstract class : Abstract classes are look like interfaces.Abstract classes may contain code although it may also have abstract method that do not have code. Abstract classes defines only signature of the method ,not implementation. The child class which inherit the abstarct class must define all the abstarct methods of its parent class .

         e.g        abstract class myItem

                    {

                        abstract protected function gettheitem();
abstract protected function settheitem();

                    }

The variable is set, but it is blank. So you need to check if it is blank also.

if (isset($_POST["mailid"]) && !empty($_POST["mailid"])) {
    echo "Yes, mailid was submitted";
}else{  
    echo "No, mailid was not submitted";

Simply extend the SoapHeader to create a Wsse compilant authentication:

class WsseAuthHeader extends SoapHeader {

private $wss_ns = 'http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd';

function __construct($user, $pass, $ns = null) {
    if ($ns) {
        $this->wss_ns = $ns;
    }

    $auth = new stdClass();
    $auth->Username = new SoapVar($user, XSD_STRING, NULL, $this->wss_ns, NULL, $this->wss_ns); 
    $auth->Password = new SoapVar($pass, XSD_STRING, NULL, $this->wss_ns, NULL, $this->wss_ns);

    $username_token = new stdClass();
    $username_token->UsernameToken = new SoapVar($auth, SOAP_ENC_OBJECT, NULL, $this->wss_ns, 'UsernameToken', $this->wss_ns); 

    $security_sv = new SoapVar(
        new SoapVar($username_token, SOAP_ENC_OBJECT, NULL, $this->wss_ns, 'UsernameToken', $this->wss_ns),
        SOAP_ENC_OBJECT, NULL, $this->wss_ns, 'Security', $this->wss_ns);
    parent::__construct($this->wss_ns, 'Security', $security_sv, true);
}
}



$wsse_header = new WsseAuthHeader($username, $password);
$x = new SoapClient('{...}', array("trace" => 1, "exception" => 0));
$x->__setSoapHeaders(array($wsse_header));

If you need to use ws-security with a nonce and a timestamp, Peter has posted an update version on http://php.net/manual/en/soapclient.soapclient.php#114976 of which he wrote that it did work for him:

    private $wsu_ns = 'http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd';

    function __construct($user, $pass)
    {
        $created    = gmdate('Y-m-d\TH:i:s\Z');
        $nonce      = mt_rand();
        $passdigest = base64_encode(pack('H*', sha1(pack('H*', $nonce) . pack('a*', $created) . pack('a*', $pass))));

        $auth           = new stdClass();
        $auth->Username = new SoapVar($user, XSD_STRING, NULL, $this->wss_ns, NULL, $this->wss_ns);
        $auth->Password = new SoapVar($pass, XSD_STRING, NULL, $this->wss_ns, NULL, $this->wss_ns);
        $auth->Nonce    = new SoapVar($passdigest, XSD_STRING, NULL, $this->wss_ns, NULL, $this->wss_ns);
        $auth->Created  = new SoapVar($created, XSD_STRING, NULL, $this->wss_ns, NULL, $this->wsu_ns);

        $username_token                = new stdClass();

Deactivating Zopim Live Chat on Mobile Devices

Tue, 06 Sep 2016 06:29:27 +0000

How about deactivating Zopim Live Chat on Mobile Devices?

The problem is that, on mobile phones with really small screens, even the minimized chat bubble can take up a significant portion of valuable screen real estate. If you happen to tap it, the minimize button may actually end up beyond the top of the screen disabling people from accessing your site. To make matters worse, a cookie will keep re-opening the window each time you reload the page.
