啞劇「圖像/ JPEG」在這一點上，我很困惑的東西的圖像稱爲這-thing.png（如PNG24創造出來的Photoshop CS5的 ），作爲image/jpeg上傳到kcfinder。PHP PNG圖像上載與KCFINDER 3.12
與TriID分析，示出的圖像是完全100％PNG

但是，當內$ _FILES可變數據[（鍵（$ _ FILES）] [ 'tmp_name的值']，達到kcfinder \ core \ class \ browser.php函數moveUploadFile（作爲參數$文件）... mm類型從tm p_name以JPEG形式出現，而不是以PNG形式出現。
修飾功能，用於測試目的，包括從getimagesize() not returning false
protected function moveUploadFile($file, $dir) {
$message = $this->checkUploadedFile($file);
if ($message !== true) {
if (isset($file['tmp_name']))
@unlink($file['tmp_name']);
return "{$file['name']}: $message";
}
$filename = $this->normalizeFilename($file['name']);
$target = "$dir/" . file::getInexistantFilename($filename, $dir);
echo "<h3>PHP_FILES foreach</h3>";
foreach ($_FILES['upload']['name'] as $key => $value){
echo "<pre>";
print_r(getimagesize($_FILES['upload']['tmp_name'][$key]));
echo "</pre>";
}
echo "<h3>TEMP FILE</h3>";
echo "</strong>file variable</strong>";
echo "<pre>";
print_r($file);
echo "</pre>";
echo "</strong>file.tmp_name</strong>";
echo "<pre>";
print_r($file['tmp_name']);
echo "</pre>";
$tmp_name_imagesize = getimagesize($file['tmp_name']);
echo "<pre>";
print_r($tmp_name_imagesize);
echo "</pre>";
if (imagetypes() & IMG_PNG) { echo "PNG Supported"; } else { echo "PNG not supported."; }
// mkaatman - move tmp file to /tmp/ to check its MD5SUM result
$temporary_file_path = $file['tmp_name'] . ".uploaded";
move_uploaded_file($file['tmp_name'], $temporary_file_path);
die();
}
結果代碼，文件的上傳期間此-thing.png，表明該媒體類型是實際上JPG和不是PNG（這是部分，我似乎無法包裹我的頭）。

顯然，這個文件php92C2.tmp.uploaded是上傳的文件，到/tmp/目錄。
我已經加入.png到文件的末尾，使用Windows Rename，文件分析的目的。

但是，如果圖像是通過PHP直接測試（複製+粘貼到目錄）
<?php
$image_file = "this-thing.png";
$image_file_details = getimagesize($image_file);
echo "<pre>";
print_r($image_file_details);
echo "</pre>";
?>
結果，讀取該圖像是在-事實PNG。

內kcfinder /高速緩存/ base.js功能功能_.initUploadButton =函數中使用的形式（）是你的基本，上傳形式。
<div id="upload" style="top:5px;width:77px;height:31px">
<form enctype="multipart/form-data" method="post" target="uploadResponse" action="browse.php?type=image&lng=en&opener=ckeditor&act=upload"><input type="file" name="upload[]" onchange="_.uploadFile(this.form)" style="height:31px" multiple="multiple" /><input type="hidden" name="dir" value="" /></form>

一些信息，基於所有這些信息，我似乎弄清楚不能爲什麼地球上的圖像被上傳爲PNG，回來作爲JPEG。
編輯：我已經測試，kcfinder使用從MSPAINT創建的圖像（這是它得到混亂）
所測試的PNG圖像。
結果（基於上面的代碼）。

編輯：我發現，其中圖像被從PNG轉換爲JPG
如果checkUploadedFile在期間被註釋掉文件this-thing.png出來預期PNG ....

輸出爲PNG Supported.
這是什麼輸出？ 'if（imagetypes（）＆IMG_PNG）{echo「PNG Supported」; }其他{回聲「PNG不支持。」; }' – mkaatman
@mkaatman'PNG Supported' – Killrawr
如果是這樣，你的'var_dump（$ file）;'它是你期望的文件嗎？不知何故，我懷疑你運行的是錯誤的文件，或者你的某個方法正在改變文件。 'pp_array（）'做什麼？ – mkaatman
