Insert multiple rows into mysql (items separated by comma)

Question

I have a small problem :) I was searching the web but didn\'t find any solutions.

I have a value like this (got it from $_GET[])

tag1, tag2, tag3, tag4

Answer 1

$id=33;

$tag=$_GET['tag'];
$tag_Split= explode(",", $tag);

$cnt=count($tag_Split);

for($i=0;$i<$cnt;$i++)
{
mysql_query("insert into tag_table(id,tag) 
values ($id, $tag_Split[$i])");
}
