大家好，我有一个上传一个或多个图片的网站文件上传页面。
问题是每当我上传文件时我的图像都会创建拇指，因此它应该创建
上传其显示确认标志但未创建
的图像数量的大拇指图片大拇指。
实际上我已从PHP学院
下载包包含此文件（create.thumb.php），我已经调用了该函数及其上传文本
图像成功但没有在Thumbs文件夹中创建图像的拇指这里是代码：
**create.thumb.php**
<?php
function create_thumb($directory, $image, $destination) {
$image_file = $image;
$image = $directory.$image;
if(file_exists($image)){
$source_size = getimagesize($image);
if($source_size !== false){
$thumb_width = (int)$width;
$thumb_height = (int)$height;
switch($source_size["mime"]){
case "image/jpeg" : $source = imagecreatefromjpeg($image); break;
case "image/png" : $source = imagecreatefrompng($image); break;
case "image/gif" : $source = imagecreatefromgif($image); break;
} $source_aspect = round(($source_size[0] / $source_size[1]), 1);
$thumb_aspect = round(($thumb_width / $thumb_height), 1);
if($source_aspect < $thumb_aspect){
$new_size = array($thumb_width, ($thumb_width / $source_size[0]) * $source_size[1]);
$source_pos = array(0, ($new_size[1] - $thumb_height) / 2);
} elseif($source_aspect > $thumb_aspect){
$new_size = array(($thumb_width / $source_size[1]) * $source_size[0], $thumb_height);
$source_pos = array(($new_size[0] - $thumb_width) / 2, 0);
} else {
$new_size = array($thumb_width, $thumb_height);
$source_pos = array(0, 0);
} if($new_size[0] < 1){
$new_size[0] = 1;
} if($new_size[1] < 1){
$new_size[1] = 1;
} $thumb = imagecreatetruecolor($thumb_width, $thumb_height);
imagecopyresampled($thumb, $source, 0, 0, $source_pos[0], $source_pos[1], $new_size[0], $new_size[1], $source_size[0], $source_size[1]);
switch($source_size["mime"]){
case "image/jpeg" : imagejpeg($thumb, $destination.$image_file); break;
case "image/png" : imagepng($thumb, $destination.$image_file); break;
case "image/gif" : imagegif($thumb, $destination.$image_file); break;
}
}
}
}

简单的risize脚本，试试这个：
<?php
$html = PHP_EOL;
if (!empty($_FILES['images'])) {
$finfo = new finfo(FILEINFO_MIME);
for ($i=0;;$i++) {
switch (true) {
case (!isset($_FILES['images']['tmp_name'][$i])):
break 2;
case (!is_uploaded_file($filename = $_FILES['images']['tmp_name'][$i])):
case (($type = $finfo->file($filename)) === false):
continue 2;
case ($type === 'image/png; charset=binary'):
$img = imagecreatefrompng($filename);
break;
case ($type === 'image/jpeg; charset=binary'):
$img = imagecreatefromjpeg($filename);
break;
case ($type === 'image/gif; charset=binary'):
$img = imagecreatefromgif($filename);
break;
default:
continue 2;
}
list($width, $height) = getimagesize($filename);
$new_width = 100;
$new_height = (int)($new_width * $height / $width);
$new_img = imagecreatetruecolor($new_width, $new_height);
imagecopyresampled(
$new_img, $img,
0, 0, 0, 0,
$new_width, $new_height, $width, $height
);
switch (true) {
case ($type === 'image/png; charset=binary'):
imagepng($new_img, $filename);
break;
case ($type === 'image/jpeg; charset=binary'):
imagejpeg($new_img, $filename);
break;
default:
imagegif($new_img, $filename);
}
$new_filename = './tmp/'.basename($filename);
if (move_uploaded_file($filename,$new_filename))
$html .= sprintf('<p><img src="%s" /></p>'.PHP_EOL, $new_filename);
}
}
?>
