本文给大家分享了2则php生成ICO图标的代码，第一款是基于YII框架实现的，第二款是纯php编写，都非常的不错，有需要的小伙伴可以参考下1，phpthumb_ico 是生成ICO图标的类，源码如下
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] .= "x28x00x00x00"; // 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] .= "x01x00"; // WORD biPlanes; $BitmapInfoHeader[$key] .= chr($bpp[$key])."x00"; // wBitCount; $BitmapInfoHeader[$key] .= "x00x00x00x00"; // DWORD biCompression; $BitmapInfoHeader[$key] .= $this->LittleEndian2String($biSizeImage, 4); // DWORD biSizeImage; $BitmapInfoHeader[$key] .= "x00x00x00x00"; // LONG biXPelsPerMeter; $BitmapInfoHeader[$key] .= "x00x00x00x00"; // LONG biYPelsPerMeter; $BitmapInfoHeader[$key] .= "x00x00x00x00"; // DWORD biClrUsed; $BitmapInfoHeader[$key] .= "x00x00x00x00"; // DWORD biClrImportant; } $icondata = "x00x00"; // idReserved; // Reserved (must be 0) $icondata .= "x01x00"; // 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 .= "x01x00"; // 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, $y)); } }2，后台
引入类：
Yii::$enableIncludePath = false;Yii::import ( 'application.extensions.ico.phpthumb_ico', 1 );
解决生成黑色背景的问题
imagealphablending($resize_im, false);//不合并颜色,直接用$im图像颜色替换,包括透明色
imagesavealpha($resize_im, true);//不要丢了$resize_im图像的透明色
