Show all Number with exclude number in php

Question

How can I display all numbers with the exception of number 3? I am still learning to use PHP, and it's been around 2 days I can't finish it.

I have made the code listed below, however, I do not know how I can make it not show number 3.

I want to display all content A, B, C, D, E, F, G. except the letter C. in Url like this www.example.com/code.php?id=1 1 for var id 1 show all text with except 3 or C

<?php
  if(isset($_GET['id'])){
  if(is_numeric($_GET['id']))
  {
    $id = $_GET['id'];

     if($id=='1') 
    {
      while( in_array(($var = range(1,7)), array(3)));
    }
    $id = $_GET['id'];

     if($id=='2') 
    {
      while( in_array(($var = range(1,7)), array(3)));
    }

//---------------------------- Content to show ---------------
if ($var == 1) {
    print 'content A';
}

if ($var == 2) {
    print 'content B';
}

if ($var == 3) {
    print 'content C';
}

if ($var == 4) {
    print 'content D';
}

if ($var == 5) {
    print 'content E';
}

if ($var == 6) {
    print 'content F';
}

if ($var == 7) {
    print 'content G';
}
}
}
?>

and show with enter like this

content A
content B
content D
content E
content F
content G

What does that code do? According to your output, it does not display any number — Nico Haase, Jan 15 '19 at 13:22

<?php

if (isset($_GET['id'])){

    $var = range(1,7);

    $arrContent = array(
        'content A', 
        'content B', 
        'content C', 
        'content D', 
        'content E', 
        'content F', 
        'content G'
    );

    $id = (int) $_GET['id']; // Convert id to integer

    if ($_GET['id']) { // If 1
        foreach($var as $key => $value) { // Loop from 1 to 7
            if ($key == 2) { // Skip number 3 which has index 2
                continue; 
            } else{
                echo nl2br($arrContent[$key]."\n"); // Use index in $var to get content with same index
            }
        }
    }
}

I have edited the question. so it will appear more clearly – H-ndi Santoso Jan 15 '19 at 11:57
You mean when you run your script it should display all the content at once from A to G except content C? – bastien Jan 15 '19 at 12:50
Or on enter it should display a random content from A to G except C? Because this what your code is doing actually. You can check the updated answer, don't know if that is what you are looking for, your question still unclear to me. – bastien Jan 15 '19 at 12:56
please check my post again sir – H-ndi Santoso Jan 15 '19 at 13:20
Check the updated answer. It will list all content from A to G except C if `id=1`. – bastien Jan 15 '19 at 14:33

Why not use a array_filter ?

array_filter(range(1,7), function($item) { return $item !== 3; } );

I use print for content. so I want to display everything but with an exception. – H-ndi Santoso Jan 15 '19 at 11:54
