我到处寻找可能的解决方案来解决我的问题。不幸的是，我似乎无法弄清楚。我有一个基于其他图像创建图像的 .php 文件。我让脚本完全按照以前的方式工作，没有任何缺陷。但是在摆弄其他一些文件之后，它突然停止工作，并且现在在 Firefox、Chrome 和 IE 上生成损坏的 .png 图像。

include("GameEngine/Database.php");
if(isset($_GET['uid'])){
$uid = $_GET['uid'];
} else {
$uid = "1";
}
if(isset($_GET['size'])){
if($_GET['size']=='profile'){
$size = '31x40';

$size = '64x82';
}elseif($_GET['size']=='sideinfo'){
$size = '119x136';
}
} else {
$size = "119x136";
}
$herodetail = $database->HeroFace($uid);
if($herodetail['color']==0){
$color = "black";
}
if($herodetail['color']==1){
$color = "brown";
}
if($herodetail['color']==2){
$color = "darkbrown";
}
if($herodetail['color']==3){
$color = "yellow";
}
if($herodetail['color']==4){
$color = "red";
}
$geteye = $herodetail['eye'];
$geteyebrow = $herodetail['eyebrow'];
$getnose = $herodetail['nose'];
$getear = $herodetail['ear'];
$getmouth = $herodetail['mouth'];
$getbeard = $herodetail['beard'];
$gethair = $herodetail['hair'];
$getface = $herodetail['face'];
// USAGE EXAMPLE:
$body = imagecreatefrompng('img/hero/head/'.$size.'/face0.png');
if($getbeard!=5){
$beard = imagecreatefrompng('img/hero/head/'.$size.'/beard/beard'.$getbeard.'-'.$color.'.png');
}
$ear = imagecreatefrompng('img/hero/head/'.$size.'/ear/ear'.$getear.'.png');
$eye = imagecreatefrompng('img/hero/head/'.$size.'/eye/eye'.$geteye.'.png');
$eyebrow = imagecreatefrompng('img/hero/head/'.$size.'/eyebrow/eyebrow'.$geteyebrow.'-'.$color.'.png');
if($gethair!=5){
$hair = imagecreatefrompng('img/hero/head/'.$size.'/hair/hair'.$gethair.'-'.$color.'.png');
}
$mouth = imagecreatefrompng('img/hero/head/'.$size.'/mouth/mouth'.$getmouth.'.png');
$nose = imagecreatefrompng('img/hero/head/'.$size.'/nose/nose'.$getnose.'.png');
$face = imagecreatefrompng('img/hero/head/'.$size.'/face/face'.$getface.'.png');
// SAME COMMANDS:
$database->imagecopymerge_alpha($body, $face, 0, 0, 0, 0, imagesx($face), imagesy($face),100);
$database->imagecopymerge_alpha($body, $ear, 0, 0, 0, 0, imagesx($ear), imagesy($ear),100);
$database->imagecopymerge_alpha($body, $eye, 0, 0, 0, 0, imagesx($eye), imagesy($eye),100);
$database->imagecopymerge_alpha($body, $eyebrow, 0, 0, 0, 0, imagesx($eyebrow), imagesy($eyebrow),100);
if($gethair!=5){
$database->imagecopymerge_alpha($body, $hair, 0, 0, 0, 0, imagesx($hair), imagesy($hair),100);
}
$database->imagecopymerge_alpha($body, $mouth, 0, 0, 0, 0, imagesx($mouth), imagesy($mouth),100);
$database->imagecopymerge_alpha($body, $nose, 0, 0, 0, 0, imagesx($nose), imagesy($nose),100);
if($getbeard!=5){
$database->imagecopymerge_alpha($body, $beard, 0, 0, 0, 0, imagesx($beard), imagesy($beard),100);
}
// OUTPUT IMAGE:
header("Content-Type: image/png");
imagesavealpha($body, true);
imagepng($body, NULL);
?>
我尝试注释掉 header() 以便在图像渲染之前检查任何 PHP 中是否存在错误。不是这种情况。我已经尝试了标签中的所有 $variables 来检查这些是否正确呈现。他们做到了。我不知道问题可能是什么。
我现在唯一的猜测是有一个空格或回车以某种方式添加到最终渲染中导致它损坏。但是，我已经寻找这个可能的空白很久了，但似乎找不到它。
非常感谢任何提示和/或建议！
已解决此脚本包含的文件之一已保存为带有 BOM 的 UTF-8。这给了图像一个额外的字节，使其损坏。将所有文件保存为没有 BOM 的 UTF-8 解决了我的问题。
