What does this JB code really want?

$LN = $this->lengthindicator ($this->qr_mode_nm, $this->version); $dif = $this->estimatebitsmodenum ($run)  + 4 + $ln + $this->estimatebitsmode8 (1)         //+ 4 + l8-$this->estimatebitsmode8 ($run + 1);//-4-l8if ($dif > 0) {return $this->eat8 ();} function Estimatebitsmodenum ($size) {$w = (int) $size/3; $bits = $w * 10;switch ($size-$w * 3) {Case 1: {$bits + = 4;break ;} Case 2: {$bits + = 7;break;} Default: {break;}} return $bits;} function EstimateBitsMode8 ($size) {return $size * 8;} function Lengthindicator ($mode, $version) {if ($mode = = $this->qr_mode_st) {return 0;} if ($version <= 9) {$l = 0;} elseif ($version <=) {$l = 1;} else {$l = 2;} return $this->lengthtablebits[$mode [$l];} $lengthTableBits = Array (Array (9, one, 8), Array (8, 10, 12), Array (+/-);

You're out of context, who knows what's going on.

The code is not complete, I don't see what this JB code is trying to do.

Why do you love me?

Come on, settle the bill.

I can not understand it completely!

I really met a master. Ask for explanations

This code is too short, like a QR code.

Why the eat12,14 situation.

Do not understand the principle of two-dimensional code, see the code can read it?
Numeric mode digital code, from 0 to 9. If the number of digits that need to be encoded is not a multiple of 3, then the last remaining 1 or 2 digits will be converted to 4 or 7bits, then each of the other 3 digits will be 10,12,14bits corresponding to your estimatebitsmodenum
Number of digits encoded under different version:
That corresponds to your lengthindicator.

I don't understand, help you find the information: Http://coolshell.cn/articles/10590.html#jtss-tsina
