怎么不在界限内爆炸子分隔符？

Question

我有这个字符串：

text example (some text) (usb, apple (fruit), computer (technology), nature: sky)

我需要var_dump()输出explode "("：

array(3) {
  [0]=>
  string(34) "text example"
  [1]=>
  string(12) "some text"
  [2]=>
  string(12) "usb, apple, computer, nature: sky"
}

Answer 1

您可以使用带有正则表达式模式的php函数link删除您不希望在输出中显示的文本，然后使用preg_replace()函数：

explode

结果：

$string = 'text example (some text) (usb, apple (fruit), computer (technology), nature: sky)';

//Remove (fruit) and (technology) from string 
$newString = preg_replace('/ \((\w+)\)/i', ', ', $string);

//Explode with new string
$output = explode(" (",$newString);

//Remove ')' from output
var_dump(preg_replace('/\)/i', '', $output));

希望这会有所帮助。
