Можете ли вы по конвейеру получить несколько файлов с FTP?

Например, у меня есть файл с содержимым ниже.

Kluyveromyces_lactis ftp://ftp.ncbi .nlm.nih.gov/genomes/all/GCF/000/002/515/GCF_000002515.2_ASM251v1 last_Complete Genome_Major Leishmania_major_strain_Friedlin ftp://ftp.ncbi.nlm.nih.gov/genomes/all/GCF/000/002/725/GCF_000002725.2_ASM272v2 last_Complete Genome_Major Plasmodium_falciparum_3D7 ftp ://ftp.ncbi.nlm.nih.gov/genomes/all/GCF/000/002/765/GCF_000002765.5_GCA_000002765 last_Complete Genome_Major Caenorhabditis_elegans ftp://ftp.ncbi.nlm.nih.gov/genomes/all/GCF/000/002 /985/GCF_000002985.6_WBcel235 last_Complete Genome_Major Bacillus_pseudofirmus_OF4 ftp://ftp .ncbi.nlm.nih.gov/genomes/all/GCF/000/005/825/GCF_000005825.2_ASM582v2 last_Complete Genome_Major Escherichia_coli_str._K-12_substr._MG1655 ftp://ftp.ncbi.nlm.nih.gov/genomes/all/GCF/000 /005/845/GCF_000005845.2_ASM584v2 last_Complete Genome_Major Methanococcus_voltae_A3 ftp://ftp.ncbi.nlm.nih.gov/genomes/all/GCF/000/006/175/GCF_000006175.1_ASM617v2 last_Complete Genome_Major

И, если я хочу загрузить файлы Kluyveromyces_lactis .fna и .gtf, я запускаю php-код ниже

<?php
$process=new GDownloading("assembly_summary_refseq_new.txt","ftp_links_of_species_1.txt", "Chromosome");
//$process->Sorting();
$process->Download();

        $this->r_file=$ResultFile;
        $this->g_opt=$Goption;
    }
    function Sorting()
    {
        $gfile = fopen($this->s_file, "r");
        $resfile = fopen($this->r_file, "wb");
        while($line=fgets($gfile, 1000000))
        {
            if($line[0]=="#")

            $pts = explode("\t", $line);

                    $sp_name = str_replace(" ", "_", $pts[7]);
                    fwrite($resfile, "$sp_name\t$ftp_link\t$pts[10]_$pts[11]_$pts[12]\n");
                }
                else
                {
                    continue;
                }
            }
        }
        fclose($gfile);
        fclose($resfile);

    function Download()

        if(!is_dir("Chromosome"))
        {
            mkdir("Chromosome");
        }
        $download_count=0;
        while($line=fgets($ftp_link, 10000))
        {
            $dir=scandir("Chromosome");
            $pts=explode("\t", $line);
            $pts[0]=str_replace("/", "", $pts[0]);
            $pts[0]=str_replace(":","_", $pts[0]);
            if(in_array("$pts[0]", $dir))
            {
                $folder_name=$pts[0] . "_" . $download_count;
            }
            else
            {

            $link = $pts[1];
            mkdir("Chromosome/$folder_name") ;
            $file=explode("/", $link);
            $file=end($file);
            $fna=$link."/".$file."_genomic.fna.gz";
