添加换行符作为分隔符

Question

I have a function that uses comma as separator in breaking name/email pairs from a long string. I would like to modify this function to be able to detect if instead of a comma a line break is used. Here's the function that needs to be modified:

$str = '"Fname Lname" <[e-mail]>, [e-mail]';
$pairs = explode( ",", $str );
foreach( $pairs as $pair ) {
  if( strpos($pair, '<') ) {
    $output = explode( "<", $pair );
    $output['0'] = trim( str_replace( "\"", "", $output['0'] ) );
    $output['1'] = trim( rtrim( $output['1'], ">" ) );
  } else {
    $output = array();
    $output['0'] = '';
    $output['1'] = $pair;
  }
  print_r($output); // Save it to database here
}

I found a post suggesting using a file() fnction but I am not sure how to combine those two together.

$str = '"Fname Lname" <[e-mail]>, [e-mail]';
$pairs = file($str, FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES); 

Answer 1

Try this, convert to line breaks then check if exists

$str=nl2br($str);
if (strpos($str,'<br />')!==false){
$pairs = array_filter(explode( "<br />", $str ));
}

Or alternatively, you can break apart on spaces which should catch the line breaks

if (strpos($str,' ')!==false){
$pairs = array_filter(explode( " ", $str ));
}

Note; I added the array_filter because it will remove empty values for you. Also, I would suggest using the FILTER_VALIDATE_EMAIL from here http://php.net/manual/en/filter.filters.validate.php before adding to your database.
