求高手拯救我PHP变量后面带[]是什么意思
我就贴上关键代码

<br />
foreach ($logData as $key => $data) {<br />
			$kItem[] = $key;//这里变量后面的[]是什么<br />
			$dItem[] = $data;<br />
			$cshu++;<br />
			if($cshu == 8) $dItem[] = "i";<br />
		}<br />
		$field = implode(',', $kItem);<br />
		$values = "'" . implode("','", $dItem) . "'";<br />
		$this->db->query("INSERT INTO " . DB_PREFIX . "blog ($field) VALUES ($values)");

Copy after login

循环读出数组循环到第八个数据的时候修改 $dItem[]的值为i 但是在写入数据的时候这个I却是多出的
SQL语句执行错误：INSERT INTO emlog_blog (title,alias,content,excerpt,author,sortid,date,top,allow_remark,allow_tb,hide,password) VALUES ('dsa','','das','','39','-1','1380936471','n','i','y','y','n','')
Column count doesn't match value count at row 1

报错的原因是因为多出了一个I值我想把I前面的N替换掉的但是不知道为什么他就是不能替换值
