#1. PHP is very popular now. Can I learn it with zero basic knowledge? (Recommended learning: PHP video tutorial)
Compared with other languages, PHP is easier to master. Most of our students have no basic knowledge, and lack of basic knowledge will not be the main problem in learning PHP. Each employment class of Wuhan Danai's PHP discipline is equipped with a service team of 4 people, including lecturers, technical guidance, employment guidance, and class teachers, so that students with no basic knowledge can not only learn, but also achieve high salaries.
2. What can PHP do?
PHP technology is specialized in making websites, and the range of websites it can do is also very wide: such as forums (Tianya, Shuimu Tsinghua, etc.), e-commerce networks (Taobao, eBay, etc.) , cms websites (such as Youku, Tudou and other websites), 80% of websites in the world use PHP technology. The scale of websites built with PHP technology can support tens of millions of people online at the same time. Large portals such as Taobao, Sina, and Tencent are all built with PHP.
Normal PHP development is generally divided into two types, using existing framework development and using existing system transformation. Using framework development means decorating the rough room. Using system modification is to renovate the already decorated house. If you want to be fast, of course you should use an open source CMS system to modify it. Most of the functions have been written, and you only need to know a little about the front end to make it great.
Common domestic open source PHP systems include Empire CMS, PHPCMS, and DreamWeaver CMS. Blogs such as wordpress are used by people all over the world, as well as z-blog and so on. Of course, learning these open source systems also takes time. So you can also use frameworks as basic development. Of course, you need some basic skills. The most commonly used framework in China is ThinkPHP, which is most commonly used by recruitment agencies. Codeigniter or YII are also commonly used. Among them, ThinkPHP and Codeigniter are more suitable for beginners.
3. What is the future development prospect of PHP?
The PHP language has existed since 1994 and has always been among the best in terms of usage. Judging from major recruitment websites, the demand for PHP talents is far from saturated. In 2015, he was ranked first in back-end language development among the "Top Ten Most In-demand Talents on the Internet" by authoritative media.
PHP has the advantages of being open source, free, rich in frameworks, conducive to rapid development, and has a good mass base. Moreover, PHP programmers can penetrate the mobile terminal (compatible with Android and iOS phones) through hybrid development APP, which has great future development prospects. It's something you don't expect.

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。

php判断有没有小数点的方法:1、使用“strpos(数字字符串,'.')”语法,如果返回小数点在字符串中第一次出现的位置,则有小数点;2、使用“strrpos(数字字符串,'.')”语句,如果返回小数点在字符串中最后一次出现的位置,则有。

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。

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。

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。

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),
