php - How to convert an array (with TRUE and FALSE values) to binary string to ASCII characters?

Get the solution ↓↓↓

Solution:

This should work for you:

First I go through each element with and replaceTRUE ->1,FALSE ->0. Then I it into a string.

After this I simply your string into an array of 8 bits (1 byte). Then I loop through each array element with{-code-1}, convert the binary to dec with , and then get the ASCII character of it with . (Also note, that I used to make sure each element has 8 bits, otherwise I would fill it up with 0's).

Code:

<?php

    //Equivalent to: 011001000110111101100111
    $permissions = [FALSE, TRUE, TRUE, FALSE, FALSE, TRUE, FALSE, FALSE, FALSE, TRUE, TRUE, FALSE, TRUE, TRUE, TRUE, TRUE, FALSE, TRUE, TRUE, FALSE, FALSE, TRUE, TRUE, TRUE];

    $binaryPermissionsString = implode("", array_map(function($v){
        return $v == TRUE ? 1 : 0;
    }, $permissions));


    $binaryCharacterArray = str_split($binaryPermissionsString, 8);
    $text = implode("", array_map(function($v){
        return chr(bindec(sprintf("%08d", $v)));
    }, $binaryCharacterArray));

    echo $text;

?>
