爆炸不返回空字符串? [英] Explode that doesn't return empty strings?

问题描述

PHP的explode函数返回在提供的某些子字符串上拆分的字符串数组.它将返回空字符串，如下所示:

PHP's explode function returns an array of strings split on some provided substring. It will return empty strings like this:

var_dump(explode('/', '1/2//3/'));
array(5) {
  [0]=>
  string(1) "1"
  [1]=>
  string(1) "2"
  [2]=>
  string(0) ""
  [3]=>
  string(1) "3"
  [4]=>
  string(0) ""
}

是否有一些不同的函数或选项，或者会返回除空字符串以外的所有内容的?

Is there some different function or option or anything that would return everything except the empty strings?

var_dump(different_explode('/', '1/2//3/'));
array(3) {
  [0]=>
  string(1) "1"
  [1]=>
  string(1) "2"
  [2]=>
  string(1) "3"
}

推荐答案

尝试 preg_split .

$exploded = preg_split('@/@', '1/2//3/', NULL, PREG_SPLIT_NO_EMPTY);
