如何在第三次出现的事情上拆分字符串？

Question

I know "explode" splits the string and turns it into an array for every occurrence. But how do I split on the third occurrence and keep everything after the third occurrence?

Examples 1:

$split = explode(':', 'abc-def-ghi::State.32.1.14.16.5:A);

I would like this to output:

echo $split[0];  // abc-def-ghi::State.32.1.14.16.5
echo $split[1];  // A

Examples 2:

$split = explode(':', 'def-ghi::yellow:abc::def:B);

I would like this to output:

echo $split[0];  // def-ghi::yellow
echo $split[1];  // abc::def:B

Answer 1

Explanation:

First split by :: and get both the output
Now, split further output by : and get individual strings
Last, append required strings according to your requirements to get exact output.

Code:

<?php
  $str = "abc-def-ghi::State.32.1.14.16.5:A";
  $split1 = explode('::', $str)[0];
  $split2 = explode('::', $str)[1];
  $split3 = explode(':', $split2)[0];
  $split4 = explode(':', $split2)[1];
  echo $split1 . "::" . $split3;
  echo $split4;
?>
