需要单独安装的扩展
gd库, mbstring, mhash和mcrypt
1.指定了--with-apxs2=/usr/local/apache/bin/apxs以后,就不要再激活--enable-fpm和--enable-fastCGI,apxs是以php module的模式加载PHP的.
2.Mysql在编译了Mysql开发library以后,可以不用指定mysql的路径.
3.PHP编译存在基础的依赖的关系,编译PHP首先需要安装XML扩展,因为php5核心默认打开了XML的支持,其他的基础库,相应需要
4.GD -> zlib, Png, Jpg, 如果需要支持其他,仍需要根据实际情况编译扩展库,ttf库需要freetype库的支持。
5.--enable-magic-quotes,是一个极其不推荐的参数,当然,如果你需要PHP为你做这些底下的工作,实际上他也没有很彻底的解决问题。
6.-with-openssl 需要openssl库
mysqli是MySQL团队提供的MySQL驱动,具有很多实用的功能和典型特征。不过他不是MySQL于PHP平台最好的选择,PDO被证实,是一个简易、高并发性,而且易于创建和回收的标准接口。不过PDO也经历了5.3以前的内存溢出的问题,在5.3以后,在读取Oracle的LOB资源时,若不对内存进行限制,仍会内存溢出。
如果是生产环境,好像pear、shmop、ftp等,都不推荐使用,语言,都有很好很快速的选择,无需局限于使用PHP去实现。不熟悉的类库和不常用的库,也不推荐使用。
magic-quote、session.auto_start、PHP服务器信息、PHP报错信息等在编译完成后,应该第一时间关闭,避免暴露服务器信息。
PHP对应的Web Server模式,Module、fastcgi、fpm只需要一种即可,服务器不是你的试验田。fastcgi可以选择Nginx和lighttpd,其实Nginx也是使用lighttpd的spwan-fcgi进行fcgi进程管理的。fpm是使用PHP自身去管理多进程,有点类似一个后端代理。无论什么模式,在发布产品服务器,都应该做进程和线程调优,做足够多的性能及压力方面的测试,找出最好的进程数组合。
选好一种PHP OPCode cache的扩展,这个也是很重要的,linux 2.6核心下,fcgi下,xcache有较好的实践经验,其他的在并发数增加以后,性能衰减严重。
如果真的想体验宁可编译多几个PHP版本,也不要针对一个版本的PHP集合各种扩展,适应各种环境,这会让把你自己逼进窘境的。

在PHP中,trait適用於需要方法復用但不適合使用繼承的情況。 1)trait允許在類中復用方法,避免多重繼承複雜性。 2)使用trait時需注意方法衝突,可通過insteadof和as關鍵字解決。 3)應避免過度使用trait,保持其單一職責,以優化性能和提高代碼可維護性。

依賴注入容器(DIC)是一種管理和提供對象依賴關係的工具,用於PHP項目中。 DIC的主要好處包括:1.解耦,使組件獨立,代碼易維護和測試;2.靈活性,易替換或修改依賴關係;3.可測試性,方便注入mock對象進行單元測試。

SplFixedArray在PHP中是一種固定大小的數組,適用於需要高性能和低內存使用量的場景。 1)它在創建時需指定大小,避免動態調整帶來的開銷。 2)基於C語言數組,直接操作內存,訪問速度快。 3)適合大規模數據處理和內存敏感環境,但需謹慎使用,因其大小固定。

PHP通過$\_FILES變量處理文件上傳,確保安全性的方法包括:1.檢查上傳錯誤,2.驗證文件類型和大小,3.防止文件覆蓋,4.移動文件到永久存儲位置。

JavaScript中處理空值可以使用NullCoalescingOperator(??)和NullCoalescingAssignmentOperator(??=)。 1.??返回第一個非null或非undefined的操作數。 2.??=將變量賦值為右操作數的值,但前提是該變量為null或undefined。這些操作符簡化了代碼邏輯,提高了可讀性和性能。

CSP重要因為它能防範XSS攻擊和限制資源加載,提升網站安全性。 1.CSP是HTTP響應頭的一部分,通過嚴格策略限制惡意行為。 2.基本用法是只允許從同源加載資源。 3.高級用法可設置更細粒度的策略,如允許特定域名加載腳本和样式。 4.使用Content-Security-Policy-Report-Only頭部可調試和優化CSP策略。

HTTP請求方法包括GET、POST、PUT和DELETE,分別用於獲取、提交、更新和刪除資源。 1.GET方法用於獲取資源,適用於讀取操作。 2.POST方法用於提交數據,常用於創建新資源。 3.PUT方法用於更新資源,適用於完整更新。 4.DELETE方法用於刪除資源,適用於刪除操作。

HTTPS是一種在HTTP基礎上增加安全層的協議,主要通過加密數據保護用戶隱私和數據安全。其工作原理包括TLS握手、證書驗證和加密通信。實現HTTPS時需注意證書管理、性能影響和混合內容問題。
