将长字符串分成小段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

，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);
