Question

I’m so new in php. I want to ask for decbin function in PHP
let say I have this code :

 <?php
    $input= 8;
    for($i=0;$i<$input ; $i++){  
     echo decbin($i)."<br>";
    }
 ?>

then the output will be like this:

0 
1
10
11
100
101
110
111

But I want to make the output like this

000
100
100
110
100
101
110
111

Any suggested for this?

Answer 1

You use str_pad

echo str_pad(decbin($i), 3, '0') . '<br/>';

Your complete code should look like:

 <?php
    $input= 8;
    for($i=0;$i<$input ; $i++){  
     echo str_pad(decbin($i), 3, '0') . '<br/>';
    }
 ?>
