最近经常有朋友跟我讲,很想来学习php,但又不敢来学,为什么?说是有人跟他讲,php没前途,程序员一大把,php程序员日益呈现白菜价趋势。我对我的朋友讲:只要你有技术过硬的信心,你完全可以按照自己的职业规划前行。
不错,现在的php程序员很多,但这个群体中各人的素质也是参差不齐的,有不少做互联网圈子的朋友总是跟我抱怨:现在好的php程序员难招,要不招过来的是技术上混混沌沌,让做个事情总是做不好,还喜欢狮子大开口漫天要价,要么就是技术的确很过硬,但对薪金要求超出公司预算。这说明什么,这给我们一个php程序圈子里的一个怪事:最底层,没有经验或者技术半懂不懂的程序员占绝大多数,这得益于现在社会上各种培训班,有的培训班真的不太负责人,将知识过一遍,或者讲都不是太系统的讲一遍,就不去管到底学生有没有学好,这是一种不负责任的表现。导致学习者以为自己能够胜任php工作,但真正工作起来很吃力,也给企业造成很大的损失。不过也有的培训机构做的就不错,我php刚入门是在上海非凡进修学院学习的,主讲老师肖飞真的讲的不错,最近开了个php疯狂训练营,大家可以关注一下,这是后话。另一方面,php圈子里有那么一群人技术真的很不错,不过他们始终呆在php的高级圈子里,做技术总监,做项目经理,一般公司除了找猎头或朋友介绍,是很难招到他们的,这给了我们另一个启示:企业招聘最需要中级圈子里没人。
PHP语言已经连续两个月超过VB,在程序排行榜上与java,c,c++一起领跑,而且趋势还在不断上升,由于php与其搭建环境的完全开源性,在全球的网站中,80%都已经使用php搭建,其实这对php程序员的需求是相当大的。
php语言之所以这么流行,其简单易掌握性在很大程度上推进了其发展,所以想学的朋友大可不必有所顾虑,只要你有信心学好,再加上系统的培训,如果再能对手册进行细心阅读的话,那成为一个优秀的php程序员将变得很容易,切忌学习一门语言要学就学精,不要学到php,又想着c,再去学会java,那这样你永远成不了精英。

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.
