Upload PHP file that passes data to MYSQL

Question

It will be difficult to explain what I want but I will try to summarize in 2 small paragraphs.

Come on

I have a script that passes the file data .CSV and .TXT to the database MYSQL, but it only works when I put the name of my document and the document itself hosted along with it, ie I have a file importar.csv and importar.php, in the importar.php needs to be set the file importar.csv.

But what do you want to do?

I would like it to work with upload php file, ie the person (anyone) who has access to the upload area, send the file .CSVor .TXTand instead of the archive importar.php set the file importar.csv, he set the upload file.

If you don’t understand, please leave a comment and I’ll explain it better.

And the importar.php how are?

$tabela = "n_emails";
$arquivo = 'importar.csv';

$arq = fopen($arquivo,'r');

while(!feof($arq))
for($i=0; $i<1; $i++){
if ($conteudo = fgets($arq)){
    $ll++; // $ll 
    $linha = explode(';', $conteudo);// 
}

$sql = "INSERT INTO $tabela (ativo, email) VALUES ('$linha[0]', '$linha[1]')";
$result = mysql_query($sql) or die(mysql_error());
$linha = array();
}
echo "quantidade de linhas importadas = ".$ll;

I hope you have passed on all the information necessary for the understanding of all, I appreciate the help or the haha attempt.
