如何使用php从eml文件中仅将电子邮件地址提取到excel文件中

Question

I've tried this PHP code to extract email addresses from eml file. but it show me on browser like this:

Array ( [0] => [e-mail]
        [1] => [e-mail] 
        [8] => [e-mail] 
       [16] => [e-mail] 
       [23] => [e-mail] 
       [26] => [e-mail] 
       [33] => [e-mail] 
       [35] => [e-mail] [64] => [e-mail] 
       [67] => [e-mail] [68] => [e-mail] 
       [87] => [e-mail] 
       [94] => [e-mail] 
       [97] => [e-mail] 
      [104] => [e-mail] 
   )`

My PHP code is:

<?php
   $emails = array();

   foreach(rglob("*.eml") as $eml){
     $emlContent = file_get_contents($eml);
     preg_match_all('/([A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,6})/i', $emlContent, $matches, PREG_PATTERN_ORDER);


     for ($i = 0; $i < count($matches[1]); $i++) {
         $emails[] .= $matches[1][$i];
     }
   }


   $emails = array_unique($emails);
   print_r($emails);


   function rglob($pattern='*', $flags = 0, $path=''){
      $paths=glob($path.'*', GLOB_MARK|GLOB_ONLYDIR|GLOB_NOSORT);
      $files=glob($path.$pattern, $flags);

      foreach ($paths as $path) {
         $files=array_merge($files,rglob($pattern, $flags, $path));
      }

      return $files;
}

?>

Now I want to extract only all the sender email addresses into an excel file. I've searched over the internet but did not got any solution.

Hope someone will help me to solve the problem. Thanks in advance

Try adding this header information to your function, this will start a download:

    header("Content-type: application/octet-stream");
    header("Content-Disposition: attachment; filename=emails.xls");
    header("Pragma: no-cache");
    header("Expires: 0");

    foreach($emails as $email){
        echo $email;
    }
