将长字符串分成小段php [英] Break long string into pieces 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，尽管限制为1000，但我还是要通过字符串运行字符串，所以如何将字符串分成4个部分，每个部分最多包含1000个字符，而不是将单词分成两半，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.

如果您不希望切断单词，请先通过wordwrap对其进行转换，如下所述

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);
