PHP的圖像調整大小獲取名稱和路徑

Question

我想弄清楚它把新的調整大小的圖像在這裏。

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

     echo $this->uploaddir. $imageNewName .'.'.$this->ext; 
} 

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

    $newWidth = $newWidth; 
    $newHeight = $newHeight; 

    $this->dst_r = ImageCreateTrueColor($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; 
} 

    $tempFile = $_FILES['Filedata']['tmp_name']; 
    $targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/img/nonfb/'; 

$fileNameBase = $_FILES['Filedata']['name']; 
$extension = pathinfo($fileNameBase, PATHINFO_EXTENSION); 
$fileNameNEW = $imageNewName . '.' . $extension; 

$targetFile = str_replace('//','/',$targetPath) . $fileNameNEW; 
echo 'TARGET=' . $targetFile; 

move_uploaded_file ($tempFile, $targetFile); 

$image = new Image(); 
$image->setFile($targetFile); 
$image->setUploadDir($targetPath); 
$image->resize(50,50); 
$image->createFile(md5($tempFile,$fileNameNEW)); 
$image->flush() 

我可以告訴它走的是dst_r作爲當前圖像和IMG_R作爲資源圖像但林不知道如何使用呼應這些，找出它們的值。我想要做的是找出它的位置，調整大小的圖像，所以我可以重命名它。

任何幫助將是偉大的！

我假設這段代碼駐留在一個類中。正如createFile功能的第9行，該文件可能會駐留在此路徑：

echo $this->uploaddir. $imageNewName .'.'.$this->ext;
