带有PREG_SPLIT_DELIM_CAPTURE标志的preg_split仍然会使用分隔符

Question

String $uri:

/profile/asd/

I run this on the string:

$uri_arr = preg_split('/\//',$uri,-1,PREG_SPLIT_DELIM_CAPTURE|PREG_SPLIT_NO_EMPTY);

Result:

Array ( [0] => profile [1] => asd )

I thought PREG_SPLIT_DELIM_CAPTURE was supposed to conserve / if not I would use explode instead...

Answer 1

To capture the delimiters, you still need to wrap them into parentheses:

preg_split('~(/)~', '/profile/asd/', -1, PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY)

Output:

array(5) {
  [0]=>
  string(1) "/"
  [1]=>
  string(7) "profile"
  [2]=>
  string(1) "/"
  [3]=>
  string(3) "asd"
  [4]=>
  string(1) "/"
}
