關(guān)于PHP遞歸數(shù)組代碼分析
我們大家都知道PHP是一種HTML內(nèi)嵌式的語(yǔ)言,PHP與微軟的ASP頗有幾分相似,都是一種在服務(wù)器端執(zhí)行的嵌入HTML文檔的腳本語(yǔ)言,語(yǔ)言的風(fēng)格有類似于C語(yǔ)言,現(xiàn)在被很多的網(wǎng)站編程人員廣泛的運(yùn)用。文章這里詳細(xì)的介紹一下PHP遞歸數(shù)組。PHP程序需要將接收到的數(shù)據(jù)同時(shí)寫到“線上運(yùn)行的正式數(shù)據(jù)庫(kù)”和“進(jìn)行開發(fā)調(diào)試的測(cè)試數(shù)據(jù)庫(kù)”。
#T#而測(cè)試數(shù)據(jù)庫(kù)可能經(jīng)常會(huì)面臨對(duì)表結(jié)構(gòu)、字段、配置信息做調(diào)整等問(wèn)題,很不穩(wěn)定,發(fā)生錯(cuò)誤的概率很高,如果用a.php程序同時(shí)寫“正式數(shù)據(jù)庫(kù)”和 “測(cè)試數(shù)據(jù)庫(kù)”,勢(shì)必影響到線上運(yùn)行的正式服務(wù)。于是,我想到用PHP curl擴(kuò)展庫(kù)將生成的$data數(shù)組post傳遞一份給php程序,然后php程序繼續(xù)往下執(zhí)行寫“正式數(shù)據(jù)庫(kù)”的代碼。php程序?qū)?data數(shù)組傳遞給php程序就完事了,至于php如何處理,就不關(guān)php的事了,php程序即使寫“測(cè)試數(shù)據(jù)庫(kù)”失敗,也不會(huì)對(duì) php程序造成影響。
