PHP generate ICO icon using Phpthumb_ico class complete instance, icophpthumb_ico_php tutorial

The PHP generated ICO icon uses a full instance of the Phpthumb_ico class, Icophpthumb_ico

Here I am using the YII framework.

1,phpthumb_ico is the class that generates the ICO icon, the source code is as follows

Class Phpthumb_ico {function Phpthumb_ico () {return true; } function gd2icostring (& $gd _image_array) {foreach ($gd _image_array as $key = + $gd _image) {$            imagewidths[$key] = imagesx ($gd _image);            $ImageHeights [$key] = Imagesy ($gd _image); $BPP [$key] = Imageistruecolor ($gd _image)?            32:24;            $totalcolors [$key] = Imagecolorstotal ($gd _image);            $icXOR [$key] = ';                    for ($y = $ImageHeights [$key]-1, $y >= 0; $y-) {for ($x = 0; $x < $ImageWidths [$key]; $x + +) {                    $argb = $this->getpixelcolor ($gd _image, $x, $y);                    $a = round (255 * (127-$argb [' alpha '])/127);                    $r = $argb [' Red '];                    $g = $argb [' green '];                    $b = $argb [' Blue '];                    if ($bpp [$key] = = (+) {$icXOR [$key]. = Chr ($b). chr ($g) Chr ($r). chr ($a); } elseif ($bpp [$key] = = 24{$icXOR [$key]. = Chr ($b). chr ($g). chr ($R);                    if ($a <) {@ $icANDmask [$key] [$y]. = ' 1 ';                    } else {@ $icANDmask [$key] [$y]. = ' 0 '; }}//Mask bits is 32-bit aligned per scanline while (strlen ($icANDmask [$ke                y][$y]) {$icANDmask [$key] [$y]. = ' 0 ';            }} $icAND [$key] = '; foreach ($icANDmask [$key] as $y = = $scanlinemaskbits) {for ($i = 0; $i < strlen ($scanlinemaskbits); $i + = 8) {$icAND [$key]. = Chr (Bindec (Str_pad (substr ($scanlinemaskbits, $i, 8), 8, ' 0 ', str_pad_left)))                ; }}} foreach ($gd _image_array as $key = + $gd _image) {$biSizeImage = $ImageWidths [            $key] * $ImageHeights [$key] * ($BPP [$key]/8); Bitmapinfoheader- Bytes $BitmapInfoHeader [$key] = ';                              $BitmapInfoHeader [$key]. = "\x28\x00\x00\x00";            DWORD bisize;      $BitmapInfoHeader [$key]. = $this->littleendian2string ($ImageWidths [$key], 4);            LONG Biwidth;            The Biheight member specifies the combined//height of the XOR and and masks. $BitmapInfoHeader [$key]. = $this->littleendian2string ($ImageHeights [$key] * 2, 4);            LONG Biheight;                                      $BitmapInfoHeader [$key]. = "\x01\x00";               WORD biplanes; $BitmapInfoHeader [$key]. = Chr ($bpp [$key]).
