Just read the manual:

https://www.php.net/manual/en/function.hex2bin.php

hex2bin ( string $data ) : string

The function requires a string - did you give it a string? No, you gave it an array.

How do you get certain data from an array? Read the manual:

https://www.php.net/manual/en/language.types.array.php

Decoding of that hex is fine, you just have to use the entry behind the right key:

<?php

$hex = '31 30 2E 30 2E 32 36 42 2E 35 30 31 00 00 00 00';
$hey = strtr($hex, [' ' => '']);
$bin = hex2bin($hey);

var_dump($hex, $hey, $bin); // string(16) "10.0.26B.501"

And what did you find out while practicing the examples from the manual i posted a link to?

Well i change the code

$hex = ($ONUsoft[11]);
$hey = strtr($hex, [‘Hex-STRING:’ => ‘’, ’ ’ => ‘’]);
$bin = hex2bin($hey);

echo $bin ;

now it works the way i want. Тhank you again
