php - 如何在 explode 和替换期间删除逗号空格？

Question

$data = "google,facebook,youtube,twitter,bing";

$exp = explode(",",$data);

$rep = str_replace("facebook",$exp);
$final = implode(",",$rep);

echo $final

output// google,,youtube,twitter,bing

如何用逗号删除这个空格？

Answer 1

您的代码应该如下所示:

$data = "google,facebook,youtube,twitter,bing";
$exp = explode(",",$data);

foreach($exp as $key => $item)
{
   if(trim($item) == "facebook")
   {
       unset($exp[$key]); //Remove from teh array.
   }
}

$final = implode(",",$rep);
echo $final;

或者只要你的来者之后没有空格，你就可以简单地走

$data = str_replace(",facebook,",",",$data);

对于使用 str_replace 的许多复杂情况，只需使用 loopy 方法即可。
