代码

 $arquivo = fopen($_FILES["Arquivo"]["tmp_name"], "r");
$arquivo = preg_replace('/\s+/', '', $arquivo);

while (!feof($arquivo)) {
  $linhas = fread($ler,999999);
  $banco = substr($linhas,0,3);
  $lote = substr($linhas,4,7);
  $registro = substr($linhas,8,8);
}
echo "Banco: " .$banco. "<br>";
echo "Lote: " .$lote. "<br>";
echo "Registro: " .$registro. "<br>";

您是否尝试过使用file_get_contents？

试试这个..

$ar = $_FILES["Arquivo"]["tmp_name"];
$arquivo = file_get_contents($ar);
$arquivo = preg_replace('/\s+/', '', $arquivo);
