getimagesize方法可以查看图片的详细信息，如下：
> print_r(getimagesize('mnjpg.jpg')); Array ( [0] => 2250 // 宽 [1] => 1500 // 高 [2] => 3 // 类型 [3] => width="2250" height="1500" [bits] => 8 [mime] => image/png )图片类型说明
$imageTypeArray = array( 0 => 'UNKNOWN', 1 => 'GIF', 2 => 'JPEG', 3 => 'PNG', 4 => 'SWF', 5 => 'PSD', 6 => 'BMP', 7 => 'TIFF_II', 8 => 'TIFF_MM', 9 => 'JPC', 10 => 'JP2', 11 => 'JPX', 12 => 'JB2', 13 => 'SWC', 14 => 'IFF', 15 => 'WBMP', 16 => 'XBM', 17 => 'ICO', 18 => 'COUNT' );图片上传，以jpeg类型为例
$old_image = imagecreatefromjpeg($image_url); $new_image = imagecreatetruecolor($width, $height); imagecopy($new_image, $old_image, 0, 0, $x1, $y1, $width, $height); ob_start(); imagejpeg($new_image); $contents = ob_get_contents(); ob_end_clean(); imagedestroy($old_image); imagedestroy($new_image); // 新图片上传到图片服务器 $url = 'xxx/upload'; $client = Apf_Http_CurlClient::getInstance(); $ret = $client->doPost($url, array('file' => base64_encode($contents)), array(), array(), 1000); $ret = json_decode($ret, true);转载于:https://www.cnblogs.com/chenguoli/p/7607234.html
