Detect new line in text area

[Exoon]

Hi,

 

Im trying to make a script to mass update a load of links in my database but im stuck on the basics, How can i detect a new line in a text area?

 

Anyone know why this dosen't work?

 

 

<?php
if($_POST[newlinks]) {
    
    $newlinks = preg_split("\n", ($_POST['newlinks']));
    $i = 1;
    foreach ($newlinks as $newlink) {
      
      echo "$i - $newlink <br />";
      $i++;
   }
  
} else {


  echo "<form method=\"POST\" action=\"changehost.php\">";
  echo "<br /> <strong>Enter the new links to try and replace old ones</strong> <br />";
  echo "<textarea rows=\"16\" name=\"newlinks\" cols=\"84\"></textarea>";
  echo "<input type=\"submit\" value=\"Submit\" name=\"B1\">";


?>

Why are you using preg_replace? str_replace seems like it would work perfectly fine here.

 

$newlinks = str_replace("\n", "", $_POST['newlinks']);//replace all newlines with empty strings, thus removing them from the string

Im using preg_split not replace. Im going to be entering 1000s of links i want all of them split up individually so i can try and replace each link 1 by 1
