如何在PHP中使用分隔符拆分字符串？ [关闭]

Question

I have a string

1b00bd515bf8cbc5a86f3b714361fab6

and I want to break it down like this:

1b00bd51-5bf8cbc5-a86f3b71-4361fab6

How can I do this?

Answer 1

use chunk_split function split a string into smaller chunks

below:

$str = "1b00bd515bf8cbc5a86f3b714361fab6";

$str = trim(chunk_split(str_replace('-','',$str), 8, '-'), '-');
