//組裝數(shù)組插入數(shù)據(jù)庫(kù)就可以了
php保存數(shù)據(jù)到數(shù)據(jù)庫(kù)
需要轉(zhuǎn)義一下。有幾個(gè)辦法：
1，最簡(jiǎn)單，把一些危險(xiǎn)字符過(guò)濾掉，比如英文的單引號(hào)，雙引號(hào)等；
2，使用addslashes在php中進(jìn)行轉(zhuǎn)義，自己處理；
3，可以使用一些現(xiàn)成的處理方法，比如uchome自帶的getstr。這樣的好處就是對(duì)各種可能出現(xiàn)的情況處理比較好。
php代碼存在數(shù)據(jù)庫(kù)中使用
可以。
樓主可以采用這種思路：
取出數(shù)據(jù)庫(kù)--將代碼寫成php文件--保存到硬盤--利用一個(gè)模擬瀏覽器訪問(wèn)該php--結(jié)果該php被執(zhí)行
或者
取出數(shù)據(jù)庫(kù)--將代碼寫成php文件--保存到硬盤--include該php--結(jié)果該php被執(zhí)行--刪除硬盤上的php
網(wǎng)站題目：php存儲(chǔ)數(shù)據(jù)庫(kù)的代碼,php存儲(chǔ)數(shù)據(jù)庫(kù)的代碼是多少
