PHP explode function takes in more than 1 whitespace, PHP, EXPLODE, WHITESPACES

Question

I have an array with a couple of words, and I'm trying to explode it at only one whitespace, but its counting whitespaces in as well when exploding for some reason. How do I stop this?

<?php

$string = "I'm just            so peachy, right now";
$string = explode(" ", $string);

$count = count($string);
$tempCount = 0;

while ($tempCount < $count) {
echo $string[$tempCount]."$tempCount<br>";
$tempCount++;
}

?>

Actual Output:

I'm0
just1
2
3
4
5
6
7
8
9
10
11
12
so13
peachy,14
right15
now16

Expected Output:

I'm0
just1
so2
peachy,3
right4
now5

Use a preg_split, http://php.net/manual/en/function.preg-split.php, which will use a regex so you can tell it to keep all continuous white-spaces as one.

$string = 'I\'m just            so peachy, right now';
$spaced = preg_split('~\h+~', $string);
print_r($spaced);

Output:

Array
(
    [0] => I'm
    [1] => just
    [2] => so
    [3] => peachy,
    [4] => right
    [5] => now
)

What does ~\h+~ mean?

zanderwar Over a year ago

Horizontal whitespace character (+ means one or more of).

I forget about preg_split(). Great solution.

Should have added the regex demo at first. Yea, the \h is for an inline space (horizontal whitespace). The + is for one or more occurance of the previous character. The ~ are delimiters.
