如何在爆炸和更换过程中删除逗号空格？

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

如何用逗号删除此空格？

Answer 1

您的代码应如下所示：

$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;

或者只要你来后没有空间，你就可以去

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

对于使用 的许多并发症str_replace，只需使用循环方法。
