    if you're writing

    require 'something';
    if (!defined ('something');
         require 'something';

    it'll happened twice not once, it's a mistake.

    Observation: Even in below case the output comes just once.

    common.ini.php
    <h1> Tanuj's Page</h1>

    index.php
    <?php
    require_once 'common.inc.php';
    include_once 'common.inc.php';
    ?>

    Output
    Tanuj's Page   ( Just once)

    include_once may be used in cases where the same file might be included and evaluated more than once during a particular execution of a script, so in this case it may help avoid problems such as function redefinitions, variable value reassignments, etc.

    I think that the reason is that if you include a function twice it will produce an error

    If you write lots of codes, it's a good idea to use it 🙂

    hi im sorry if i'm a bit slow, but can u give a quick explanation (no need for a video, just a text response is fine) of a time where you'd rather use "include" instead of "include_once" or require/require_once? Thanks a lot!!!

    Still dont understand. Is it for if you accidentally include something twice?

    It is so definable that people who dont value the worth of PHP are not COMPUTER PROGRAMMERS 🙂

    @thesickbeat WTF do you think wordpress runs on and thus requires knowledge of to "pimp" out. It runs on php.

    @mosle123 There are 200 videos mate, not every one have the patient. Some noob went to 5 or 6 just give up.

    I am wondering why your tutorials have so low views? It should have about 100k views. 1k = 1000
