WHY PHP cURL HTTP CODE return 0 (zero)

If you try to connect with the server, then you can get a return code from it, otherwise it will fail and you get ZERO.
So if you try to connect to “www.yahoo.com/zxcv” you will get a return code of 400, if you go directly to yahoo.com, you will get 302 (and then 200 if you forward to the next page… , and if you go to “yahoocom” you will get a 0 (host no found), so with the last one, there is nobody to send a code back.

Tested using the code below.

Remove public from URL in Laravel

To remove public from URL in laravel you need to follow below steps.

Rename the server.php in the your Laravel root folder to index.php
Move all folder from public to root.
copy the .htaccess file from /public directory to your Laravel’s project root folder.

Note:- This is not a safe way. A safer way is place Laravel’s files outside your web server root and make the Laravel’s public directory your web server root. Route your website to public folder in place of public_html. You can do this with help of your server administrator.

What is self keyword in PHP

In PHP, you use the self keyword to access static properties and methods.

Below is the example to expalin self

Refer this code:

class ParentClass {
function test() {
self::demo();

}

function demo() {
echo ‘Example of self !’;
}
}

class ChildClass extends ParentClass {
function demo() {
echo ‘Return chlid class’;
}
}

$obj = new ChildClass();
$obj->test();

In this example, self::demo() will always output ‘Example of self !’.
Now we can see that self refers to the class in which it is called.
So, you should use self only when $this is not available, or when you don’t want to allow descendant classes to overwrite the current method.

If we use $this in test method it will return “Return chlid class”;
