将PHP字符串划分为基于“；除法器”；字符 - Divide PHP string into arrayed substrings based on "divider" characters

Divide PHP string into arrayed substrings based on "divider" characters

我想做的是将一个PHP字符串拆分为一组子字符串，这些子字符串基于以这些子字符串开头的"分隔符"字符分组为数组。字符*、^和%被保留为分隔符字符。因此，如果我有字符串"*Here's some text^that is meant*to be separated^based on where%the divider characters^are"，它应该被拆分并放置在数组中，如下所示：

array(2) {
    [0] => "*Here's some text"
    [1] => "*to be separated"
}
array(3) {
    [0] => "^that is meant"
    [1] => "^based on where"
    [2] => "^are"
}
array(1) {
    [0] => "%the divider characters" 
}

我完全迷上了这个。有人知道如何实现这一点吗？

您不需要$matches[0]，所以如果您想要，请取消设置：

preg_match_all('/('*[^*^%]+)|('^[^*^%]+)|(%[^*^%]+)/', $string, $matches);
$matches = array_map('array_filter', $matches);
print_r($matches);

array_filter()从捕获组子数组中删除空数组，以给出问题中所示的数组
