将长字符串分成几部分 php

问题描述

所以我有一个大约 3800 个字符的字符串，它是句子单词等.

so I have a string which is around 3800 characters, it's sentences words etc.

现在我正在运行字符串，虽然限制是 1000，那么我怎么能把字符串分成 4 段，每段最多包含 1000 个字符，而不是把单词分成两半，有什么办法吗?

Now I'm running the string through something although the limit is 1000, so how could I break the string into 4 pieces each containing a maximum of 1000 characters and not breaking words in half, is there any way to do it?

谢谢

推荐答案

您可以使用 str_split.

   $string = "the_long_string";
   $array = str_split($string, 1000); //$array will contain elements which each is 1000 chars long.

如果你想让单词不被截断，在截断它们之前通过wordwrap进行转换

if you want words not to cut off transform it through wordwrap prior to cutting them as follows

 $string = "the_long_string";
 $string = wordwrap($string, 1000, "||"); //assume your string doesn't contain `||`
 $parts = explode("||", $string);
