Problem with parsing script - file_get_contents returns only last result

[Mikos]

Hi,

it's my first post so hello to you and i hope you will be forgiving:)

I've made a basic script, which takes a urls from the form(each of them is  the new row) and then search each of those urls for an email. The problem is that only the email from the last url is returned.

print_r("show link:". $urls[$i]."<br>"); shows all urls in the form, but the print_r("show current_url:". $current_url); shows only the last one.

 

 

<?php


$urls = explode("\n", $_POST['urls']); 

$db = new mysqli('localhost', 'root', 'root', 'urls');  

if (mysqli_connect_errno()) {
echo 'Błąd: ';
exit;
}


for ($i=0; $i<count($urls); $i++){

print_r("show link:". $urls[$i]."<br>");

$current_url = file_get_contents($urls[$i]);
print_r("show current_url:". $current_url); 


preg_match( "/[\._a-zA-Z0-9-]+@[\._a-zA-Z0-9-]+/i", $current_url, $email);//email


print_r ("show email:".$email[0]);


$zapytanie = "INSERT INTO urle set adres = '$email[0]' "; 

$wynik = $db->query($zapytanie);




}

if ($wynik) {
echo $db->affected_rows ."pozycji dodano.";
} else {
echo mysql_errno() . ":" . mysql_error() .   "Wystąpił błąd przy dodawaniu urli  ";
}

$db->close();

?>

So what exactly does get printed for each iteration of the for loop from "print_r("show current_url:". $current_url);"?

when I enter for example two urls to the form, the first "print_r("show current_url:". $current_url); is empty and for the second it shows the page(url) content(without pictures).
