爆炸不适用于字符串内的多重逗号 [英] Explode does not work with multilpe commas inside the string

问题描述

为什么当我尝试爆炸字符串时它不起作用？

  $ Text =巴西，银行，家庭，英国,,,,测试，财务时间，。，ipad ,,银行，两个字,,; 
 
 $ Text_Array = explode（，，$ Text）; 
 
 $ Text_Array = array_filter（$ Text_Array）; 
 
 print_r（$ Text_Array）; 
  

我希望将所有标记除以一个逗号，并删除任何空格和重复的标记。 / p>

我希望得到这样的结果： b
$ b

brazil，banks，home，uk ，测试，财务时间，ipad，两个字;

请问，你能帮我实现这个目标么？

删除任何空格和重复标签，那么你还需要添加 array_unique code> with array_filter

  $ textAray = array_unique（array_filter （$ textAray））; 
  

注意 ..请不要删除。在结果中..这是一个更好的方式来过滤结果

  $ text = 巴西，银行，家，英国,,,,测试，财务时间，。，iPad，银行，两个字，; 
 $ textArray = array_unique（preg_split（/[,.]+/，$ text））; 
 $ textArray = array_filter（$ textArray）; 
 echo implode（，，$ textArray）; 
  

输出

 巴西，银行，家庭，英国，测试，财务时间，ipad，两字
  

I try to find the answer here and in Google but no luck!

Why it does not work when I try to explode the string?

$Text = "brazil,banks,home,,uk,,,,test,financial times,.,ipad,,banks,,Two words,,";

$Text_Array = explode(",",$Text);

$Text_Array = array_filter($Text_Array);

print_r($Text_Array);

I would like to have all my tags divide by ONE comma and remove any space and duplicate tags.

I would like this result:

"brazil,banks,home,uk,test,financial times,ipad,Two words";

Please, can you help me to achieve this?

解决方案

If you want to remove any space and duplicate tags then you need to also add array_unique with array_filter

$textAray = array_unique(array_filter($textAray));

Note .. Please this would not remove the . in the result .. here is a better way to filter your results

$text = "brazil,banks,home,,uk,,,,test,financial times,.,ipad,,banks,,Two words,,";
$textArray = array_unique(preg_split("/[,.]+/", $text));
$textArray = array_filter($textArray);
echo implode(",", $textArray);

Output

brazil,banks,home,uk,test,financial times,ipad,Two words
