这是我的代码：
$data = 'iVBORw0KGgoAAAANSUhEUgAAABwAAAASCAMAAAB/2U7WAAAABl'
. 'BMVEUAAAD///+l2Z/dAAAASUlEQVR4XqWQUQoAIAxC2/0vXZDr'
. 'EX4IJTRkb7lobNUStXsB0jIXIAMSsQnWlsV+wULF4Avk9fLq2r'
. '8a5HSE35Q3eO2XP1A1wQkZSgETvDtKdQAAAABJRU5ErkJggg==';
$data = base64_decode($data);
$im = imagecreatefromstring($data);
if ($im !== false) {
header('Content-Type: image/png');
imagepng($im);
imagedestroy($im);
}
else {
echo 'An error occurred.';
}
我想将以这种方式生成的图像保存到目录中.我该如何做？
这是imagepng的正确语法：
imagepng($im,"/path/where/you/want/save/the/png.png");
根据PHP manual：
bool imagepng ( resource $image [,string $filename [,int $quality [,
int $filters ]]] )filename – The path to save the file to.
If not set or NULL,the raw image stream will be outputted directly.
