如何使用phpThumb生成缩略图并将其保存到文件中?

phpthumb thumbnails arrays file php

我不知道如何用phpThumb类生成缩略图,因为数组已经有了文件路径。然后将每个图像的结果保存在另一个路径上,但名称相同。

谢谢大家;)

编辑:

    echo "A iniciar gerador de miniaturas para a Ã¡rea de cliente: \n";
    include $wincli['files']['phpThumbClass'];
    $files = file_list($wincli['dirs']['logos']);

    $phpThumb = new phpThumb();
    foreach( $files as $file ) {
        echo "  # A converter o ficheiro '".basename($file)."' : ";
        if(is_file($file)){         
            $phpThumb->setSourceFilename($file); 
            $phpThumb->setParameter('w', 880);
            $phpThumb->setParameter('h', 241);
            $phpThumb->setParameter('q', 90);
            $phpThumb->setParameter('zc', 1);
            $outputFilename = $wincli['dirs']['logosthumbs'].$file;

            if($phpThumb->GenerateThumbnail()){
                if($phpThumb->RenderToFile($outputFilename)){
                    echo "OK \n";
                }else{
                    echo "Falhou (Ao guardar no ficheiro)\n";
                }
            }else{
                echo "Falhou (Ao gerar miniatura)\n";
            }
        }else{
            echo "Falhou (Ficheiro inexistente)\n";
        }
    }

这是调试:
