获取字符串的前5个单词的最佳方法是什么? 如何将字符串分成两部分，使得第一个子字符串具有原始字符串的前5个单词，第二个子字符串构成原始字符串的其余部分

What is the best way to get the first 5 words of a string? How can I split the string into two in such a way that first substring has the first 5 words of the original string and the second substring constitutes the rest of the original string

推荐答案

$pieces = explode(" ", $inputstring);
$first_part = implode(" ", array_splice($pieces, 0, 5));
$other_part = implode(" ", array_splice($pieces, 5));

explode将原始字符串分成单词数组，array_splice让您获得这些单词的特定范围，然后implode将范围重新组合成单​​个字符串.

explode breaks the original string into an array of words, array_splice lets you get certain ranges of those words, and then implode combines the ranges back together into single strings.
