如何使用PHP中的参数执行。exe并将输出放到txt文件中？

Question

cd C:\inetpub\wwwroot\webclient\db\nucleotide
blastdbcmd -entry $gi -db $DatabaseName -outfmt %f -out $text_files_path\result.txt

$gi = 1000232109;
$cmd = "-entry $gi -db $DatabaseName -outfmt %f";
exec("C:\inetpub\wwwroot\webclient\db\nucleotide\blastdbcmd.exe $cmd" , &$output, &$return_var);
file_put_contents("$text_files_path/result.txt", $output);  //result.txt created
echo $return_var;    // 1 is printed

第2代码：

$handle = popen('C:/inetpub/wwwroot/webclient/db/nucleotide/blastdbcmd.exe 2>&1', 'w');
$cmd = "-entry $gi -db $DatabaseName -outfmt %f";
exec("$cmd" , $output);
file_put_contents("$text_files_path/mm.txt", $output); //result.txt created
echo "hello";
pclose($handle);

第3代码：

exec("C:\inetpub\wwwroot\webclient\db\nucleotide\blastdbcmd.exe -db nr -entry $gi -outfmt %f -out $text_files_path/result.txt 2>&1"); //result.txt doesn't created

第4代码：

exec("cd C:\inetpub\wwwroot\webclient\db\nucleotide && blastdbcmd.exe -db nr -entry $gi -outfmt %f -out $text_files_path/result.txt 2>&1"); //result.txt doesn't created

exec("C:\\Windows\\System32\\cmd.exe /c \"C:\inetpub\wwwroot\webclient\db\nucleotide\blastdbcmd.exe -entry $gi -db $DatabaseName -outfmt %f -out $text_files_path\result.txt\" 2>&1");  //result.txt doesn't created

$cmd = "-entry $gi -db $DatabaseName -outfmt %f";
exec("C:\inetpub\wwwroot\webclient\db\nucleotide\blastdbcmd.exe $cmd" , &$out, &$return_var);
$output = "";
echo $out;      // "Array" is printed
foreach ($out as $line) {
echo $out;      // nothing printed
echo $line;      // nothing printed
$output .= $line;
}
file_put_contents("$text_files_path/result.txt", $output);
echo $return_var // 1 is printed

exec("cd C:\\inetpub\\wwwroot\\webclient\\db\\nucleotide && blastdbcmd.exe -entry $gi -db $DatabaseName -outfmt %f 2>&1",&$out, &$return_var);

注意$out是一个数组：

exec("yourcommand.exe", $out);

$output = "";

foreach ($out as $line) {
    $output .= $line;
}

file_put_contents("C:\\Users\\MyUser\\Documents\\result.txt", $output);

编辑：

改变

exec("C:\inetpub\wwwroot\webclient\db\nucleotide\blastdbcmd.exe $cmd", 
      &$out, &$return_var);

exec("C:\inetpub\wwwroot\webclient\db\nucleotide\blastdbcmd.exe $cmd 2>&1",
      &$out, &$return_var);
