我有这个奇怪的行为不端的脚本。它在 Windows 7 (Easy PHP 12.0, PHP 5.4.4, Apache 2.4.2) 中运行正常，但在 LinuxMint 13 (Apache 2.2.22 Ubuntu) 中不起作用我知道 linux 区分大小写，所以我仔细检查了文件路径，我用过error_reporting(E_ALL)，但没有错误。

<?php
$DumpHere='../Img/Gallery/DumpHere/';
$ThumbsFolder='../Img/Gallery/Thumbs/';
$PreviewFolder='../Img/Gallery/Preview/';
$Files=array_diff(scandir($DumpHere), array('..', '.'));

echo '<div id="FileList" >';
echo "<ul>";
foreach ($Files as $key => $list) {
    echo ("<li>".$list."</li>");
}
echo "</ul>";
echo "</div> <!-- closes FileList -->";

echo '<div id="WorkArea"><form action="insertGalleryTitles.php" method="post"><ul>';
foreach ($Files as $key => $Processed) {

    $filename = $DumpHere.$Processed;

    // Get new dimensions
    list($width, $height) = getimagesize($filename);
    $ratio = $width/$height;
    $outputHeight = 500*$ratio;

    // Resample thumbnail
    $image_p = imagecreatetruecolor(70, 70);
    $image = imagecreatefromjpeg($filename);
    imagecopyresampled($image_p, $image, 0, 0, 0, 0, 70, 70, $width, $height);
    // Output Thumbnail
    imagejpeg($image_p, $ThumbsFolder.'thumb_'.$Processed, 100);
    // Resample preview
    $image_p = imagecreatetruecolor(500, $outputHeight);
    $image = imagecreatefromjpeg($filename);
    imagecopyresampled($image_p, $image, 0, 0, 0, 0, 500, $outputHeight, $width, $height);
    // Output Preview
    imagejpeg($image_p, $PreviewFolder.'preview_'.$Processed, 100);
    echo '<li><img src="'.$ThumbsFolder.'thumb_'.$Processed.'">';
    echo '<input type="text" name="title['.$Processed.']" value="vyplň popisek">';
}


echo "</li>";

echo '</ul><input type="submit" ></form></div>';
?>
