PHP generates ICO icons based on yii Framework

This article will share with you two pieces of code for generating ICO icons in php. The first one is implemented based on the YII Framework, and the second one is written in pure php, which is very good, for more information, see section 1. phpthumb_ico is the class for generating ICO icons. 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] == 32) {            $icXOR[$key] .= chr($b).chr($g).chr($r).chr($a);          } elseif ($bpp[$key] == 24) {            $icXOR[$key] .= chr($b).chr($g).chr($r);          }           if ($a < 128) {            @$icANDmask[$key][$y] .= '1';          } else {            @$icANDmask[$key][$y] .= '0';          }        }        // mask bits are 32-bit aligned per scanline        while (strlen($icANDmask[$key][$y]) % 32) {          $icANDmask[$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 - 40 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])."\x00";             // wBitCount;      $BitmapInfoHeader[$key] .= "\x00\x00\x00\x00";               // DWORD biCompression;      $BitmapInfoHeader[$key] .= $this->LittleEndian2String($biSizeImage, 4);      // DWORD biSizeImage;      $BitmapInfoHeader[$key] .= "\x00\x00\x00\x00";               // LONG  biXPelsPerMeter;      $BitmapInfoHeader[$key] .= "\x00\x00\x00\x00";               // LONG  biYPelsPerMeter;      $BitmapInfoHeader[$key] .= "\x00\x00\x00\x00";               // DWORD biClrUsed;      $BitmapInfoHeader[$key] .= "\x00\x00\x00\x00";               // DWORD biClrImportant;    }      $icondata = "\x00\x00";                   // idReserved;  // Reserved (must be 0)    $icondata .= "\x01\x00";                   // idType;    // Resource Type (1 for icons)    $icondata .= $this->LittleEndian2String(count($gd_image_array), 2); // idCount;   // How many images?     $dwImageOffset = 6 + (count($gd_image_array) * 16);    foreach ($gd_image_array as $key => $gd_image) {      // ICONDIRENTRY  idEntries[1]; // An entry for each image (idCount of 'em)       $icondata .= chr($ImageWidths[$key]);           // bWidth;     // Width, in pixels, of the image      $icondata .= chr($ImageHeights[$key]);          // bHeight;     // Height, in pixels, of the image      $icondata .= chr($totalcolors[$key]);           // bColorCount;   // Number of colors in image (0 if >=8bpp)      $icondata .= "\x00";                   // bReserved;    // Reserved ( must be 0)       $icondata .= "\x01\x00";                 // wPlanes;     // Color Planes      $icondata .= chr($bpp[$key])."\x00";           // wBitCount;    // Bits per pixel       $dwBytesInRes = 40 + strlen($icXOR[$key]) + strlen($icAND[$key]);      $icondata .= $this->LittleEndian2String($dwBytesInRes, 4);    // dwBytesInRes;  // How many bytes in this resource?       $icondata .= $this->LittleEndian2String($dwImageOffset, 4);   // dwImageOffset;  // Where in the file is this image?      $dwImageOffset += strlen($BitmapInfoHeader[$key]);      $dwImageOffset += strlen($icXOR[$key]);      $dwImageOffset += strlen($icAND[$key]);    }     foreach ($gd_image_array as $key => $gd_image) {      $icondata .= $BitmapInfoHeader[$key];      $icondata .= $icXOR[$key];      $icondata .= $icAND[$key];    }     return $icondata;  }   function LittleEndian2String($number, $minbytes=1) {    $intstring = '';    while ($number > 0) {      $intstring = $intstring.chr($number & 255);      $number >>= 8;    }    return str_pad($intstring, $minbytes, "\x00", STR_PAD_RIGHT);  }   function GetPixelColor(&$img, $x, $y) {    if (!is_resource($img)) {      return false;    }    return @ImageColorsForIndex($img, @ImageColorAt($img, $x, $y));  } }
