Capture e-mail from pages

Question

I have an e-mail system with the address:

 http://www.site.com.br/123/123/123.php?p=1&codelist=1

that goes up to:

 http://www.site.com.br/123/123/123.php?p=460&codelist=1

(p=1 is the page)

That is, 460 pages. In this system I have all the data of my customers.

I need a code that accesses these 460 urls and captures only the email listed on the site and ignores other data. Anyway, just email and save on a TXT.

Can anyone help me? I have no idea how.

Answer 1

example - ideone - capture email

$url="http://www.site.com.br/123/123/123.php?p=1&codelist=1";
$text=file_get_contents($url);

$res = preg_match_all(
"/[a-z0-9]+[_a-z0-9\.-]*[a-z0-9]+@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})/i",
$text,
$matches
);

//caso haja somente um email
$email = reset($matches[0])."\n";
file_put_contents('emails.txt', $email, FILE_APPEND);
// fim caso haja um email

/* caso haja mais de um email
foreach($matches[0] as $email){
    file_put_contents('emails.txt', $email."\n", FILE_APPEND);
}
*/

file_get_contents - Reads all the contents of a file to a string

The function preg_match_all() return an integer with the number of occurrences found by the regular expression.

reset() returns the array internal pointer to the first element and returns the value of the first element of the array.

file_put_contents writes a string to a file, if this file does not yet exist it creates the file.

FILE_APPEND adds a value to an already created file.

The above script is for a page, but nothing prevents you from making a loop by varying the value of p in $url

for ($x = 1; $x <= 460; $x++) {
   $url="http://www.site.com.br/123/123/123.php?p=".$x."&codelist=1";
   $text=file_get_contents($url);

   $res = preg_match_all(
"/[a-z0-9]+[_a-z0-9\.-]*[a-z0-9]+@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})/i",
  $text,
  $matches
  );

  //caso haja somente um email
  $email = reset($matches[0])."\n";
  file_put_contents('emails.txt', $email, FILE_APPEND);
  // fim caso haja um email
}
