如果可能的话，请帮个忙，我一直在尝试更改它，但我没有成功，我想在我的 php 文件中更改它，但没有结果！

现在下面的这个脚本是一个调整大小的脚本，但是它重命名了我的文件......我不需要它这样做，你能看到它并告诉我如何删除文件的重命名吗？

我知道这与： $image->createFile(md5($tempFile)); 我尝试删除md5，但仍然没有...

谢谢！

function setFile($src = null) {
$this->ext = strtoupper(pathinfo($src, PATHINFO_EXTENSION));
if(is_file($src) && ($this->ext == "JPG" OR $this->ext == "JPEG")) {
$this->img_r = ImageCreateFromJPEG($src);
} elseif(is_file($src) && $this->ext == "PNG") {
$this->img_r = ImageCreateFromPNG($src);
} elseif(is_file($src) && $this->ext == "GIF") {
$this->img_r = ImageCreateFromGIF($src);
}
$this->img_w = imagesx($this->img_r);
$this->img_h = imagesy($this->img_r);
}

function resize($largestSide = 100) {
$width = imagesx($this->img_r);
$height = imagesy($this->img_r);
$newWidth = 0;
$newHeight = 0;

if($width > $height){
$newWidth = $largestSide;
$newHeight = $height * ($newWidth / $width);
}else{
$newHeight = $largestSide;
$newWidth = $width * ($newHeight / $height);
}

$this->dst_r = ImageCreateTrueColor($newWidth, $newHeight);
imagecopyresampled($this->dst_r, $this->img_r, 0, 0, 0, 0, $newWidth, $newHeight, $width, $height);
$this->img_r = $this->dst_r;
$this->img_h = $newHeight;
$this->img_w = $newWidth;
}

function createFile($output_filename = null) {
if($this->ext == "JPG" OR $this->ext == "JPEG") {
imageJPEG($this->dst_r, $this->uploaddir.$output_filename.'.'.$this->ext, $this->quality);
} elseif($this->ext == "PNG") {
imagePNG($this->dst_r, $this->uploaddir.$output_filename.'.'.$this->ext);
} elseif($this->ext == "GIF") {
imageGIF($this->dst_r, $this->uploaddir.$output_filename.'.'.$this->ext);
}
$this->output = $this->uploaddir.$output_filename.'.'.$this->ext;
}

function setUploadDir($dirname) {
$this->uploaddir = $dirname;
}

function flush() {
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/';
$targetFile = str_replace('//','/',$targetPath) . $_FILES['Filedata']['name'];

imagedestroy($this->dst_r);
unlink($targetFile);
imagedestroy($this->img_r);

}

}

$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/';
$targetFile = str_replace('//','/',$targetPath) . $_FILES['Filedata']['name'];

move_uploaded_file ($tempFile, $targetFile);

$image = new Image();
$image->setFile($targetFile);
$image->setUploadDir($targetPath);
$image->resize(800);
$image->createFile(md5($tempFile));

尝试更改为

$image->createFile('resized_'.$_FILES['Filedata']['name']);


function createFile($output_filename = null) {
    if($this->ext == "JPG" OR $this->ext == "JPEG") {
        imageJPEG($this->dst_r, $this->uploaddir.$output_filename, $this->quality);
    } elseif($this->ext == "PNG") {
        imagePNG($this->dst_r, $this->uploaddir.$output_filename);
    } elseif($this->ext == "GIF") {
        imageGIF($this->dst_r, $this->uploaddir.$output_filename);
    }
    $this->output = $this->uploaddir.$output_filename;
}

$_FILES['Filedata']['name']您将文件的实际名称 ( ) 与临时名称 ( )混淆了$_FILES['Filedata']['tmp_name']。第一个是客户端上传的文件。第二个是服务器在服务器机器上创建的一个临时文件。因此，您必须在此处使用实际的客户端名称。

这会让你的一天

$image->createFile(preg_replace("/\.[^\.]*$/", "", $targetFile));
