Combine PREG_SPLIT_DELIM_CAPTURE results - php

Question

I'm splitting a string following this format:
| + anything goes here + single space
The following regular expression corresponds to said pattern:
/(\|\S*)/
Using preg_split with PREG_SPLIT_DELIM_CAPTURE oddly returns the delimiter into two parts. Is there a flag or option to combine these resulting outputs?
$string = "|one |two |three this is a phrase |four";
$result = preg_split('/(\|\S*)/', $string, NULL, PREG_SPLIT_NO_EMPTY | PREG_SPLIT_DELIM_CAPTURE);
What I get:
array(7) {
[0]=>
string(4) "|one"
[1]=>
string(1) " "
[2]=>
string(4) "|two"
[3]=>
string(1) " "
[4]=>
string(6) "|three"
[5]=>
string(18) " this is a phrase "
[6]=>
string(5) "|four"
}
What I want:
array(5) {
[0]=>
string(5) "|one "
[1]=>
string(5) "|two "
[2]=>
string(7) "|three "
[3]=>
string(17) "this is a phrase "
[4]=>
string(5) "|four"
}

Answer 1

Simply catch another whitespace at the end of the word, and you'll get this:
/(\|\S*\h*)/ || /(\|\S*\s*)/
So your code will be:
<?php
$string = "|one |two |three this is a phrase |four";
$result = preg_split('/(\|\S*\s*)/', $string, NULL, PREG_SPLIT_NO_EMPTY |
PREG_SPLIT_DELIM_CAPTURE);
var_dump ($result);
