在 php 中分解多个分隔符

Question

我的数组看起来像：

{flower},{animals},{food},{people},{trees}

我想和{、,&}一起爆炸。

我的输出应该只包含大括号内的单词。

我的代码：

$array = explode("},{", $list);

执行此代码后 $array 将是

$array = Array ( 
    [0] => {flower 
    [1] => animals 
    [2] => food
    [3] => people 
    [4] => trees} 
)

但输出数组应该是：

$array = Array ( 
    [0] => flower 
    [1] => animals 
    [2] => food
    [3] => people 
    [4] => trees 
)

任何人都可以告诉我如何修改我的代码以获得这个数组吗？

Answer 1

我会选择 preg_split 如下所示

<?php

$list = "{flower},{animals},{food},{people},{trees}";
$array = preg_split('/[},{]/', $list, 0, PREG_SPLIT_NO_EMPTY);
print_r($array);
?>

输出为

Array
(
    [0] => flower
    [1] => animals
    [2] => food
    [3] => people
    [4] => trees
)

Answer 2

您可以尝试使用正则表达式而不是拆分字符串来提取单词：

$list = "{flower},{animals},{food},{people},{trees}";

// Match anything between curly brackets
// The "U" flag prevents the regex to make a single match with the first and last brackets
preg_match_all('~{(.+)}~U', $list, $result);

// Only keep the 1st capturing group
$words = $result[1];
var_dump($words);

输出：

array(5) {
  [0]=>
  string(6) "flower"
  [1]=>
  string(7) "animals"
  [2]=>
  string(4) "food"
  [3]=>
  string(6) "people"
  [4]=>
  string(5) "trees"
}
