用某种空格分割字符串

Question

I've got the following code:

$output2 = 'text

more text

ja';
$explode = explode('

', $output);

This works fine and the $explode array prints the following:

Array
(
    [0] => text
    [1] => meer text
    [2] => ja
)

However, the following code doesn't work and I don't know how to fix it:

$output = 'text



more text



ja';

$explode = explode('

', $output);

The $explode array prints the following:

Array
(
    [0] => text
    

    
  //more text
    

    
ja
)

This might seem like a weird question. But the first example is a test I made manually. But the second example is what is actually returned from the database.

You can use preg_split to split your string:

<?php
$output = 'text
&NewLine;
&NewLine;more text
&NewLine;
&NewLine;ja';

$explode = preg_split('/(&NewLine;|(
||
))+/', $output, -1, PREG_SPLIT_NO_EMPTY);

The following solution to split on double 
:

$output = 'text



more text



ja

nein';

$explode = preg_split('/(
||
)*(
(
||
)*){2}/', $output, -1, PREG_SPLIT_NO_EMPTY);
