$parts = preg_split('/\s+/', $str);
回答by AliAvci
To separate by tabs:
要按制表符分隔：
$comp = preg_split("/[\t]/", $var);
To separate by spaces/tabs/newlines:
用空格/制表符/换行符分隔：
$comp = preg_split('/\s+/', $var);
To seperate by spaces alone:
单独用空格分隔：
$comp = preg_split('/ +/', $var);
$comp = preg_split('/ +/', $var);

This works:
这有效：
$string = 'A B C D';
$arr = preg_split('/[\s]+/', $string);

The author asked for explode, to you can use explode like this
作者要求explode，你可以这样用explode
$resultArray = explode("\t", $inputString);
$resultArray = explode("\t", $inputString);
Note: you must used double quote, not single.
注意：您必须使用双引号，而不是单引号。

I think you want preg_split:
我想你想要preg_split：
$input = "A B C D";
$words = preg_split('/\s+/', $input);
var_dump($words);

instead of using explode, try preg_split: http://www.php.net/manual/en/function.preg-split.php
而不是使用爆炸，尝试 preg_split：http://www.php.net/manual/en/function.preg-split.php

In order to account for full width spacesuch as
为了考虑全宽空间，例如
full width

The answers provided by other folks (Ben James) are quite good and I have used them. As user889030 points out, the last array element may be empty. Actually, the first and last array elements can be empty. The code below addresses both issues.
其他人（本詹姆斯）提供的答案非常好，我已经使用过它们。正如 user889030 指出的那样，最后一个数组元素可能为空。实际上，第一个和最后一个数组元素可以为空。下面的代码解决了这两个问题。
# Split an input string into an array of substrings using any set
# whitespace characters
function explode_whitespace($str) {
# Split the input string into an array
$parts = preg_split('/\s+/', $str);
# Get the size of the array of substrings
$sizeParts = sizeof($parts);
# Check if the last element of the array is a zero-length string
if ($sizeParts > 0) {
$lastPart = $parts[$sizeParts-1];
if ($lastPart == '') {
array_pop($parts);
$sizeParts--;
}
# Check if the first element of the array is a zero-length string
if ($sizeParts > 0) {
$firstPart = $parts[0];
if ($firstPart == '')
array_shift($parts);
}
}
return $parts;
}

Explode string by one or more spaces or tabs in php example as follow:
<?php
$str = "test1 test2 test3 test4";
$result = preg_split('/[\s]+/', $str);
var_dump($result);
?>
/** To seperate by spaces alone: **/
<?php
$string = "p q r s t";
$res = preg_split('/ +/', $string);
var_dump($res);
?>

@OP it doesn't matter, you can just split on a space with explode. Until you want to use those values, iterate over the exploded values and discard blanks.
@OP没关系，你可以用explode在一个空间上分裂。在您想要使用这些值之前，请迭代分解的值并丢弃空白。
$str = "A B C D";
$s = explode(" ",$str);
foreach ($s as $a=>$b){
if ( trim($b) ) {
print "using $b\n";
}
}
