如何抓住第一行字符串并在php中显示？

Question

Below is my code:

<?php 
 $array = explode("
", $order['payment_address']);
 $firstLine = $array[0];
 echo $firstLine;
 ?>

What i am trying to do is grab the name of customer in first line from $order['payment_address'] and print it. Payment_address includes several lines with customer name on top. Tried the code by Ben Pearl Kahan and output is now as -

Bob Smith 12

Line 1: Bob Smith 12 Line 2: Kannaught Place Delhi 282010 Uttar Pradesh India

While i want just "Bob Smith".

I am a novice. Plz help.

Answer 1

If you are not sure about what's inside your variable, always var_dump(). To view in browser

echo '<pre>'; var_dump($order['payment_address']); echo '</pre>';

The following regex would split at any linebreak-sequence or <br> and return first non empty item.

$firstLine = preg_split('~<br */?>|\R~i', $order['payment_address'], -1, PREG_SPLIT_NO_EMPTY)[0];

See demo at eval.in
