本文給大家分享了2則php生成ICO圖標的代碼，第一款是基于YII框架實現的，第二款是純php編寫，都非常的不錯，有需要的小伙伴可以參考下

1，phpthumb_ico 是生成ICO圖標的類，源碼如下

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] .= "/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));

}

}

2，后臺

引入類：

Yii::$enableIncludePath = false;

Yii::import ( 'application.extensions.ico.phpthumb_ico', 1 );

解決生成黑色背景的問題

imagealphablending($resize_im, false);//不合并顏色,直接用$im圖像顏色替換,包括透明色

imagesavealpha($resize_im, true);//不要丟了$resize_im圖像的透明色
