Which one is better, php web or python web?
(Recommended learning: PHP video tutorial)
In terms of the number of frameworks and maturity, PHP is better than Python;
From In terms of development efficiency, Python has an absolute advantage;
Under the current circumstances, PHP has more advantages. PHP has outstanding performance advantages in web development and can quickly develop small and medium-sized websites.
In addition, there are many open source programs, such as dedecms ecshop wordpress discuz and so on.
php frameworks are also very rich, such as thinkphp, which is powerful, easy to learn, compact and flexible
The Yii framework is completely object-oriented and has a high learning threshold, but its functions are particularly powerful
Zend Framework is an officially recommended large-scale heavyweight framework
And the mysql database, apache server, and Linux system that are matched with PHP are all open source products. You don’t have to spend money or worry about infringement, so PHP is the home for web development. A must-have programming language.
The advantages of PHP include:
1. PHP open source code
2. All PHP source code is actually available.
3. PHP is free
4. Compared with other technologies, PHP itself is free and open source.
5. Quickness
The program is developed quickly, runs quickly, and the technology itself is learned quickly. Embedded in HTML: Because PHP can be embedded in the HTML language, it is comparable to other languages. Editing is simple, practical, and more suitable for beginners.
6. Strong cross-platform capability
Since PHP is a script that runs on the server side, it can run under UNIX, LINUX, WINDOWS, and Mac OS.
7. High efficiency
PHP consumes very few system resources.
8. Image processing
Use PHP to dynamically create images. PHP image processing uses GD2 by default. And can also be configured to use image magick for image processing.
9. Object-oriented

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。

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。
