Thanks a lot !
This code doesn't detect IE 11,
you could add a test : elseif(preg_match('/Trident/i',$u_agent))

Keep up the good work.
On my linux your script reports wrongly 32bit while I've 64bit:

Your browser: Mozilla Firefox 116.0 on Linux (32 Bit) reports:
Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/116.0

I've found your code because I was looking how to detect MS Edge

// Detecting Linux Architecture
// Line 30 --> 35:

if(preg_match('/WOW64/i', $u_agent)) {
    $bit = '64';
}
elseif(preg_match('/X\d+_64/i', $u_agent)) {
    $bit = '64';
}  
else {
    $bit = '32';
}
