Today with the proliferation of the Internet, it is not easy to do well in this industry. However, the development of Internet programming languages and the emergence of the PHP programming language have also won the world's development trend.
This article takes a look at the development prospects of PHP in China.
1. PHP is developing rapidly in China
As a superpower, China is also following the trend of the world, and the development of PHP in China is also unfolding rapidly.
PHP is also developing rapidly in our country, and more and more programmers choose PHP development.
The employment prospects of PHP programmers are also very good, especially in some big cities, the demand for PHP programmers is very large, and there is a lot of PHP training. Here is an introduction to the salary of PHP programmers in Shenzhen.
PHP programmer's salary is determined based on personal ability, work experience and other factors. The salary range of PHP programmers is generally between 4500 and 500000. It is not difficult to understand that the salary difference is so big. No company can work directly without hiring people, so programmers with more work experience have higher salaries.
Since you have chosen PHP development, if you want to develop better, your first priority is to improve your PHP technology as soon as possible.
2. Advantages of PHP language
1. Low threshold
In C/C , Java (Java tutorial Java training), PHP, ASP (ASP training), among these development languages, PHP is the easiest language to learn. The learning cost is 1/10 of C and JAVA, and 1/2 of ASP.
2. Little competition
PHP is developing rapidly. There are basically no PHP courses in universities and few training institutions. As a result, there are very few programmers who master PHP. From the perspective of job hunting, comparing PHP recruitment information with JAVA or ASP, the recruitment volume of PHP reaches 1/3 of JAVA and ASP, but the number of PHP applicants is only 1/40 of JAVA and ASP.
3, Demand is booming
Baidu, Sina, Sohu, Taobao, Dangdang, Tencent QQ and other Internet (IT training computer training computer training) related companies are When using PHP, there is a strong demand for PHP talents. However, the most troublesome problem for Internet companies is that they cannot recruit personnel with actual PHP learning experience, let alone personnel who have received professional training in PHP.
4, Big room for development
In the pervasive Internet application environment, new concepts such as Web2.0, cloud computing, and the Internet of Things will continue to give birth to new industries and service. The technical system that supports these new industries and services is none other than PHP. With the rise of 3G and mobile Internet technology, more and more WEB applications have chosen PHP as the mainstream technical solution.
Getting started with PHP is quick, and it is very convenient for processing files, data, remote connections, and network programming. Officials also say this: the cost of learning PHP is very low, so it is easy for you to use it.
This idea is also common, and even most PHPers themselves think so. This also makes more people feel that there are too many people learning PHP, competition is stimulating, and the salary of PHP programmers will naturally not be too high. .
In fact, this is not the case. It mainly depends on ability.
3. PHP employment prospects
PHP is a very excellent and simple web development language, and Linux
, Apache
, MySQL
are closely combined to form the open source golden combination of LAMP
, which not only reduces the cost of use, but also increases the development speed to meet the needs of new interactive network development application.
In comparison with other similar programming languages, PHP has the characteristics of fast development speed, high operating efficiency, good security, strong scalability, open source and freedom.
Looking back at the development process of PHP in the past 10 years and looking forward to the development trend of the Internet industry in the future, we can draw the conclusion: PHP’s development momentum is unstoppable and will surely become the mainstream technology in the field of WEB development in the future. system.

php把负数转为正整数的方法:1、使用abs()函数将负数转为正数,使用intval()函数对正数取整,转为正整数,语法“intval(abs($number))”;2、利用“~”位运算符将负数取反加一,语法“~$number + 1”。

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

判断方法:1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式;2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的,因此真实天数需要在此基础上加1。

在php中,可以使用substr()函数来读取字符串后几个字符,只需要将该函数的第二个参数设置为负值,第三个参数省略即可;语法为“substr(字符串,-n)”,表示读取从字符串结尾处向前数第n个字符开始,直到字符串结尾的全部字符。

方法:1、用“str_replace(" ","其他字符",$str)”语句,可将nbsp符替换为其他字符;2、用“preg_replace("/(\s|\ \;||\xc2\xa0)/","其他字符",$str)”语句。

查找方法:1、用strpos(),语法“strpos("字符串值","查找子串")+1”;2、用stripos(),语法“strpos("字符串值","查找子串")+1”。因为字符串是从0开始计数的,因此两个函数获取的位置需要进行加1处理。

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
