爆炸数组逗号但不在方括号内

I have a string:

我有一个字符串:

$var = "[Item 1],[Item 2],[Item, 3]";

When I use explode:

当我使用爆炸时:

$var = explode(",", $var);

This also explodes out the comma inside the square brackets.

这也会爆出方括号内的逗号。

I would like to return:

我想回复:

[Item 1]
[Item 2]
[Item, 3]

Running through a foreach () {} statement which I am using. Any ideas?

运行我正在使用的foreach(){}语句。有任何想法吗?

3 个解决方案

#1

$var = "[Item 1],[Item 2],[Item, 3]";

$var = explode("],[", $var);

print_r($var);

--doh forgot that the delimiter is lost so um a crude option to put those [] back in:

- 忘了分隔符丢失所以这是一个粗略的选择,把那些[]放回去:

<?php
$var = "[Item 1],[Item 2],[Item, 3]";

$var = explode("],[", $var);

foreach ($var as $v){

  if(substr($v,0,1)!='['){
   $v='['.$v; 
  }

    if(substr($v,-1)!=']'){
$v=$v.']'; 
  }

    $out[]=$v; 



}
echo '<pre>';
print_r($out);

may be better to switch to a regular expression split, i'll write that in a sec

可能会更好地切换到正则表达式拆分,我会在一秒钟内写出来

最佳性感答案:

It will not work which you want. But it can be done with

它不会工作你想要的。但它可以完成

$var = "[Item 1],[Item 2],[Item, 3]";

$varArr = explode("],", $var);

$newArr= array();
foreach($varArr as $key=>$val)
    $newArr[$key] = $val . "]";

echo "<pre>";
print_r($newArr);
echo "</pre>";

How about using regular expression to extract those information?

如何使用正则表达式提取这些信息?

$var = "[Item 1],[Item 2],[Item, 3]";
preg_match_all("(\[.+?\])", $var, $result);

print_r($result[0]);

#1

$var = "[Item 1],[Item 2],[Item, 3]";

$var = explode("],[", $var);

print_r($var);
