php怎么开启垃圾回收，黑客为什么可以做到无需知道源码的情况下找出系统漏洞？
感谢邀请。
每天活跃在互联网上的应用成百上千万，包括PC端以及目前越来越主流的移动端，不仅有通过浏览器访问的，还有需要安装客户端的，不仅有与服务器强交互的，还有独立运行的本地软件。
而这其中，开源的（包括开放源码的）产品少之又少。但，这并不妨碍一个黑客找出其中的漏洞。换句话说，找漏洞并不需要源码。
当然了，在有源码的情况下，挖洞是一件难度系数指数下降的事情。虽然读懂一个大型软件源码耗时又耗力，但对于黑客来说，可以略去其中大半的代码来阅读，只关心可能造成危险的部分。就像一名建筑工程师看一份大楼的施工图，要看懂大楼的结构、建筑材料、水电线路等等各方各面，而对于《Prison Break》中的Michael Scofield可能只关心地下管道的分布。
那么，在没有源码的情况下，黑客怎么挖洞呢？这种情况，我们可以称之为黑盒。而挖洞，的确需要与程序编辑者持有完全相反的角度和看法。对于输入输出点，程序猿考虑的是正确的输入获得正确的输出，而黑客则考虑特殊的非法输入获得异常的有价值输出。那系统登录来说，程序猿考虑的是用户输入注册的用户名、口令能够在登录时与数据库中的数据匹配成功，而黑客则会尝试引起数据库查询异常的输入作为用户名、口令内容，希望应用返回更多数据库中的有效数据。
对于黑客来说，不知道源码情况下，只要有输入就可以了，不管是应用具有的功能页面，还是一个输入接口，通过一种叫做模糊测试的技术就可以开始你的挖洞之旅。模糊测试可以构造一系列正常和异常的输入值，根据应用的返回来判断脆弱点的存在。
在黑客的武器库中，模糊测试只是其中一个利器，像什么漏扫、逆向、脱壳、注入、暴破等等不一而足。
作为程序猿，在编写程序时不仅要从正向角度完成应用的功能，还需要从黑客角度逆向分析应用在处理异常输入时的反应，才能做出高安全的应用。
程序员的职业生涯能有几年？
我也不知道算不算转型成功了。可能跑题了，但是也可以看看我的经历吧。我在转型之前半年也是颈椎、腰椎疼，现在一点毛病都没有，反而胖了很多。
程序员经历16年毕业，8 月份在北京找了个小公司，入职前端。也就是 8k 吧，干了 4 年吧，涨到了 11k，老板也没给涨了。19年的中秋节，跳槽到一个不错的公司吧，也就是 300 多人。相比之前的 30 多人，看起来很不错了，薪资涨到了 18k。两家公司氛围完全不同第一家公司完全是慢节奏，甚至是停滞不前了。我一个人花了有半年时间把内部系统前后端进行分离。（前端/后端都自己写了）这半年时间内，基本没有任何开发任务。甚至我不主动推动前后端分离，每天摸鱼也可以。但是为了自己的成长，自己学习用 Vue 搭建了前端，后端还是 PHP 框架。其实很多人都觉得 Vue 简单，那都是在学习过的，而我则是看视频，边开发边学习，没有任何人和我讨论，走了很多弯路，其实最后上线的已经是 2.0版本了，因为自己在学习过程中，看到之前的代码，太垃圾了，所以抛弃了。又从头开始。而第二家公司则是很忙，从 9 月中秋入职，摸了 10 多天鱼，过了国庆假期，从 0 开始一个全新的项目。基本上到了21 年的 1 月底。3 个多月，基本上每天都是 11 点以后下班，单休，我记忆深刻的就是连着 3 个星期，没有休息一天。每天就是下班打车，攒一个星期报销一次，每次基本上都是小 1k 了。实在是项目负责人压力太大，传递到我们这里。好的就是项目上线后，销售很给力，马上就见收益了。换工作经历其实家里一直催我回山西老家，但是山西的薪资实在是给不上来。也就不考虑了，只考虑考公务员或者事业编，国企之类稳定性好的。从 17 年开始，基本上太原附近有此类考试，我都会报名参加，但是在北京，自己疲于应付工作，也没沉下心来好好学习，一直也没考上。21 年 9 月份，知道太原招辅警，纳入编制管理，市财政统筹，也有五险一金，但是这个编制是跟单位，不跟着人，觉得这也是一条路，而且招的人很多，我记得 490 多人。也就看了几天书去考试了。我这个岗位是招 18 个人，笔试过后，自己是第八名还是第九名，觉得稳了，然后体测，体测是 1：5 的比例，相当于我这个岗位有 90 个人可以体测，体测有 摸高、10m*4折返跑、1000m 基本上前两项不会卡太多人，但是 1000m 是真可怕了，要求是 4 分 25 秒及格，我是4分完成的，绝大多数人是不及格的，不及格到什么程度 90 个人去体测，跑进 4 分 25 秒的不超过 25 个。然后就是面试，面试也就是自己看了几天面试书，其实作用不大，也是顺利通过。体检入职了。我还记得是 20 年 12 月 24 号体检，体检完，还没等到结果，就被直接拉去封闭培训了。（北京的工作还没辞职了。不过在体检之前，和领导通过气了，大概率是过年前离职）在培训过程中，跟领导说，我回不去了，在山西工作了。培训了没一个月吧，因为疫情，避免人群聚集，就都分配到工作岗位了。工资不到 4000（含五险一金），取暖费 3360 ，应该只有这些，没有其他的了，至少我目前收到的信息就是这些。感受还要一个月，也就入职一年了。但是这一年，说实话，可以说是一无所获吧。房贷都是靠北京的存款在顶着，但是生活节奏确实慢了很多，也可以蹭着身边的朋友们吃吃喝喝。想跑滴滴吧，不认识路，想送外卖，又嫌累。最近去朋友公司逛了逛，他说我老了很多，眼睛里没有光了，颓废了很多，不再有那种通宵撸代码的精气神。也在想着自己搞自媒体，但是自己文笔确实不是很好。也没爆款，还是需要继续探索。也准备着明年的省考，不说在北方，至少是在山西，公务员还算是最好的岗位了吧。如果有在太原也想搞自媒体的，可以讨论讨论。共同学习一下，咱们也体会一下幸存者偏差的感觉如何学习音标？
音标是学习英语的第一步，想要学好音标需要认识音标、会读音标，这样以后才能认识单词。在学习音标前，我们要先知道国际音标有48个，元音有20个，辅音有28个，元音又分为单元音和双元音，单元音有12个，双元音有8个。
音标数目
在上表中，我们可以看到音标有48个，现在我们常说的国际音标也是48个。

元音部分
辅音部分
音标的分类
最实用的分类方式是：元音=长元音+短元音+双元音；辅音=清辅音+浊辅音。
英语一共有48个国际音标，包括20个元音，28个辅音。
20个元音包括5个长元音：/i:/、/ɜ:/、/u:/、/a:/、/ɔ:/；
7个短元音：[i] [ə] [ɔ] [u] [ʌ] [e] [æ]；
8个双元音：/eɪ、/aɪ/、/ɔɪ/、/ɪə/、/eə/、/ʊə/、/əʊ/、/aʊ/；
注意：
1、长元音顾名思义就是发的音比较长而饱满；短元音则发的音比较短而急；
2、双元音就是两个单元音拼在一起，成为组合音。双元音发音的特点是前面的单元音发音长，后面的发音比较短。
28个辅音包括：轻辅音/p/ /t/ /k/ /f/ /θ/ /s/ /ʃ/ /ts/ /tʃ/ /tr/ /h/
浊辅音 /b/ /d/ /g/ /v/ /ð/ /z/ /ʒ/ /dz/ /dʒ/ /dr/ /r/
鼻音 /m/ /n/ /ŋ/
半元音 /j/ /w/
边音 /ǀ/

学习步骤
抄写
抄写音标，并了解音标特点。
对音标的基本认知
1、区别长短音带“：”的音标发音相对较长不带“：”的音标发音相对较短。
2、区别清辅音和浊辅音核心区别：清辅音声带不震动，浊辅音声带振动。
模仿练习
找合适的视频学习学习跟读。例如b站上《【赖世雄48个英语音标朗读示范，美音英音对照版-哔哩哔哩】 【https://b23.tv/sHYQFZ3】》、《【李咏梅老师英语（音标部分）——最牛的初中英语老师！没有之一！李咏梅国际音标 （完整版发音篇）-哔哩哔哩】 https://b23.tv/U1pmjNE》、《【纯正英式发音】这是BBC出品的到现在为止最棒的英语发音教程（完整版）-哔哩哔哩】 https://b23.tv/gZzDKl5》，以上几个视频都非常不错，详细讲解每个音标的读法。注意视频一定至少跟读5遍，才能确保你的学习效果。
也可以通过下面这个视频观察发音口型的变化。
《【48个英语音标示范读音-哔哩哔哩】 https://b23.tv/mt9vVaK》
1、模仿练习，学习国际音标的发音，要注意观察老师的口型，观察发音部位的变化，主动模仿发音，初学可以对着镜子模仿练习，特别是元音发音的舌位高低，口腔开口度大小与音色关系十分密切，可以通过镜子观察口型上的区别，观察舌尖、舌面、舌叶的活动情况，比如u和o、i和e、e和ε等等，掌握准确口腔开口度，对于准确发音具有非常重要的意义。
2、听音训练:学习国际音标需要认识48个音标，通过反反复复的听力练习，达到强化记忆。听音训练，如果有条件，可以多听老师朗读音标，也可以使用录音带反复听音，本课件中的每个音素，都可以循环倾听，强化记忆。
3、多动口，动口是加强实践的关键和核心，听音也好，模仿也好，比较也好，最终要归结到自己发音这一目标上来，所以勤动口是掌握国际音标发音的关键。俗话说，"三天不写手生，三天不念口生"，说的就是要加强动手动口能力的培养。因此学习国际音标，要时时加强语音训练，勤动口，反复实践练习，在实践中比较，在实践中体会差别，做到熟能生巧，这样自然就掌握国际音标的发音了。
重点音标讲解
单元音
[i:] =“一”
[ɪ]：[ɪ]开口要比[i:]稍大，注意比较两图口型。
[e] 嘴张45°，[æ]嘴张90°
[ɜ:r] [ər]=“二”
[ə]=额（不卷舌）
[ʌ]：开口比“啊”略小
[ɑ:r]=卷舌的“啊”
[ɑ] =“啊”
[ɔ] =开口稍大的“哦”
[ɔ:r]=卷舌的“哦”
[u:]核心：双唇由半开微突，过渡到合嘴圆唇
[ʊ] 发成噘嘴的[ə],气流向外。
双元音
双元音较简单，大多数可进行类比，注意双元音的重音在第一个音标，即前一个音读的稍重，后一个音读的较轻。
[eɪ]=“A”
[aɪ]=“I”
[əʊ]=“O”
[ɔɪ]=“哦一”
[ɪə]=ear
[eə]=air
[ʊə]=“乌尔”
辅音
大部分辅音跟“汉语拼音”都有相似之处，直接看视频模仿即可，这里只讲解易错发音。
爆破音：
[t] [p] [k] 不要读成[tə] [pə] [kə] 注意：它们声带不震动
摩擦音：
[f][v] 咬唇音，注意上齿咬下唇
[θ][ð]
上下齿轻咬舌头，发音时能看到你的舌头露出
[ʃ]=不发音的“诗” [ʒ]= “日”
[r]=撅嘴＋卷舌的“热” [h]=不发音＋舌头平放的“喝”
鼻音
[m] 合嘴
[n] 舌前部抵住上颚
[ŋ] 嘴巴张开
舌侧音[l]
元音前：跟拼音“l”发音一致元音后：发“l”的前半段
半元音
[j] “也”
[w] =圆唇噘嘴的“我”
破擦音
[tʃ]= 不发声的“吃”
[dʒ]= “居”
[ts]=不发声的“次”
[dz]=“子”
[tr] 先发“t”，在发“r”，最后结合在一起
[dr] 同上
词汇拼读
1、规划拼读任务，拿出单词书或课本词汇表，找只含1~2个音节的单词拼读，20个为一组，每天练习3组，当然如果有时间，多进行几组也OK，加强效果。后期难度逐渐加大。
2、输入法识别词汇，每拼读一个词汇，都对着X飞输入法的语音识别功能朗读，看能否被输入法识别出单词，用机器来检测是否读的准确。
3、听词汇跟读，不管输入法识别出单词，还是没识别出单词，都要查手机字典，来听一遍听力，并跟读，模仿语调和轻重读音。
例如：Cash driver apartment money breakfast lawyer agency
学习计划
1、国际音标，一共48个，每天学4个，12天学完，元音和辅音每天各学习两个。
2、学完以后结合和音标相关的单词，每天坚持读一个小时，第二天要把第一天的一块儿读，第三天要把前两天的一块儿读，依次类推，坚持学完所有的音标，就可以读字典上任何一个单词。
3、长期坚持下去，会发现其实很多字母和音标有着关联，比如ph都发音标f的音，字母u发尖a的音，类似的规律，当大家坚持下来以后会发现很多，同时你甚至可以听到单词的发音就能把单词拼出来，直接就把背单词的问题解决了，音标会读，单词会读，单词会背，听力当然也不再是问题。自己总结出来的规律说明真的学会了，同时自己得出来的结论要比老师直接告诉你印象更深刻，同时最重要的是用起来更容易。
注意事项
1、了解发音要领，模仿老师口型
学习语音，一定要注意口型，并仔细揣摩每个音标的发音要领，特别是相似音标的发音区别。
零基础学员不要以为盯着老师的口型就好了，其实发音很多都是内部器官看不到的， 所以需要老师正确的发音示范，跟着老师一起读，然后再加上老师给的一些技巧，继续跟读，老师感觉哪有问题，再帮着纠正，这样一系列过程才是练成标准发音的秘籍。
2、 单词拼读实战，一对一纠正错误
养成一口纯正口语最重要的还是练习练习再练习，单词拼读实战训练，巩固你的发音。不断读，不断纠正，训练单个音标到训练多个单词，在学习语音的过程中，再掌握一些基础的词汇。
3、辩音练习，纠正错误，掌握发音规律
训练难度会随着课程的深入不断加强，但还是训练相同的内容，一节课很多类似的训练内容。音标中很多类似的发音，将相似音放在一起对比再练习，舌头和耳朵在这很重要。

PHP作为当下主流的脚本语言，在各大互联网公司都能看到它的身影。很多人评价PHP是安全高效的Web编程语言，其实我要说的是，PHP的安全性并不高！如果在项目开发时不去做必要的安全优化，那项目上线后很容易被注入攻击。那该如何避免呢？
对用户提交的数据务必做过滤及转义处理对于Web开发而言，我们务必要清楚的知道，用户提交过来的数据是不能保证是否合法的，所以需要对用户提交的数据做一些过滤（过滤掉敏感词，如：select 、' 这类SQL构造词汇），同时用户提交的数据中可能会带一些恶意的JS或CSS代码，同样需要做转义处理，防止在前端渲染页面时执行这些JS或CSS。
代码中严禁采用SQL拼接的方式构造SQL语句很多初级PHPer在写SQL时喜欢采用字符串拼接的方式来构造SQL，殊不知这样会导致SQL注入，严谨作法应该是使用SQL预编译（参数绑定）的方式来传递参数，防止通过构造字符串的方式来进行SQL注入。
PHP配置文件安全配置PHP配置文件中有许多关于安全方面的配置，比如说：magic_quotes_gpc ，这个配置开启后会分析用户提交的数据（POST、GET、Cookie），如果这些数据中含有特殊字符（如：单引号、双引号、反斜线等）则会进行自动转义。
如果没有开启这个配置，那我们对于用户提交过来的POST、GET、Cookie数据需要手动调用addslashes函数来转义。
以上就是我的观点，对于这个问题大家是怎么看待的呢？欢迎在下方评论区交流 ~ 我是科技领域创作者，十年互联网从业经验，欢迎关注我了解更多科技知识！哔哩哔哩上有什么好的初学者编程教学吗？
这里总结一下编程初学者必须了解的2018十大最佳编程语言
2018十大最佳编程语言第一名Python
Python是一种面向对象的解释型计算机程序设计语言。Python是纯粹的自由软件，源代码和解释器CPython遵循 GPL（GNU General Public License）许可。Python语法简洁清晰，特色之一是强制用空白符（white space）作为语句缩进。第二名C#
C#是微软公司发布的一种面向对象的、运行于.NET Framework之上的高级程序设计语言。C#是一种安全的、稳定的、简单的、优雅的，由C和C++衍生出来的面向对象的编程语言。它在继承C和C++强大功能的同时去掉了一些它们的复杂特性（例如没有宏以及不允许多重继承）。C#综合了VB简单的可视化操作和C++的高运行效率，以其强大的操作能力、优雅的语法风格、创新的语言特性和便捷的面向组件编程的支持成为.NET开发的首选语言。第三名Java
Java programming language具有目前大部分编程语言所共有的一些特征，被特意设计用于互联网的分布式环境。Java具有类似于C++语言的"形式和感觉"，但它要比C++语言更易于使用，而且在编程时彻底采用了一种"以对象为导向"的方式。使用Java编写的应用程序，既可以在一台单独的电脑上运行，也可以被分布在一个网络的服务器端和客户端运行。另外，Java还可以被用来编写容量很小的应用程序模块或者applet，做为网页的一部分使用。applet可使网页使用者和网页之间进行交互式操作。
第四名JS
JavaScript一种直译式脚本语言，是一种动态类型、弱类型、基于原型的语言，内置支持类型。它的解释器被称为JavaScript引擎，为浏览器的一部分，广泛用于客户端的脚本语言，最早是在HTML（标准通用标记语言下的一个应用）网页上使用，用来给HTML网页增加动态功能。
第五名Swift
Swift，苹果于2014年WWDC（苹果开发者大会）发布的新开发语言，可与Objective-C*共同运行于Mac OS和iOS平台，用于搭建基于苹果平台的应用程序。Swift是一款易学易用的编程语言，而且它还是第一套具有与脚本语言同样的表现力和趣味性的系统编程语言。Swift的设计以安全为出发点，以避免各种常见的编程错误类别。第六名C++
C++是C语言的继承，它既可以进行C语言的过程化程序设计，又可以进行以抽象数据类型为特点的基于对象的程序设计，还可以进行以继承和多态为特点的面向对象的程序设计。C++擅长面向对象程序设计的同时，还可以进行基于过程的程序设计，因而C++就适应的问题规模而论，大小由之。C++不仅拥有计算机高效运行的实用性特征，同时还致力于提高大规模程序的编程质量与程序设计语言的问题描述能力。第七名Arduino
Arduino是一款便捷灵活、方便上手的开源电子原型平台。包含硬件（各种型号的Arduino板）和软件（Arduino IDE)。第八名php
PHP（超文本预处理器）是一种通用开源脚本语言。用PHP做出的动态页面与其他的编程语言相比，PHP是将程序嵌入到HTML（标准通用标记语言下的一个应用）文档中去执行，执行效率比完全生成HTML标记的CGI要高许多；PHP还可以执行编译后代码，编译可以达到加密和优化代码运行，使代码运行更快。
第九名Ruby
Ruby是一种简单快捷的面向对象（面向对象程序设计）脚本语言，在20世纪90年代由日本人松本行弘(Yukihiro Matsumoto)开发，遵守GPL协议和Ruby License。
第十名Go
Go是一种新的语言，一种并发的、带垃圾回收的、快速编译的语言。它具有以下特点：
它可以在一台计算机上用几秒钟的时间编译一个大型的Go程序。Go为软件构造提供了一种模型，它使依赖分析更加容易，且避免了大部分C风格include文件与库的开头。
