Open source solutions can be of great help to you, such as:
- Open source code is completed by many people, so the results are often better than those completed by one person.
- You can get free code updates and upgrades, otherwise you need to write these new content yourself.
- You save development time while improving the quality of your project
Having been a web developer for so many years, I have compiled a list of PHPcomponents that can be deployed very easily in any project that I often use. .
Send email
Every website needs to send emails. Although PHP's email() function is good, it is powerless when we need to send attachments or send using the SMTP protocol. So in this case, you should use phpmailer.

User Management
Another commonly used module is the user management module. Use this module to enable users to log in, log out, and register. I personally felt that I couldn’t find a good component to complete this task, so I wrote a Php user class myself. This component can even be used in applications that need to be released to the public, as it can be customized to use different data tables, variable types, etc.
Get RSS
Have you ever thought about adding a component to obtain RSS information in your program? Although it is easy to write such a component (Tutorial), more often than not you need more comprehensive functionality, in which case you need to use Magpie RSS.
Geolocation
Many times you will want to know which countries and regions your website visitors come from. Maxmind provides a solution to this problem. (Tutorial)
Get remote information
Sometimes the function of RSS cannot meet your needs for obtaining remote information, because you want to capture and save the information of the entire web page. At this time you will definitely need the htmlSQL class component. You can use SQL statements to get web page information, cool right?
Quote Notice
In our day and age, sending and receiving trackbacks is a very important function of a website. It can be done very easily if you use the php trackback component.
Template system
The template system is a component used by all websites. Template engines can save you a lot of time and make it very easy to change the style and design of your website pages. Smarty is a very excellent template system, basically all PHP websites are using it.
BB Code
BB code used to be a feature of forums, but as more and more websites use this feature to make themselves more user-friendly, I believe you also want to give this feature a try. But the problem is that writing BB code component requires a lot of time and experience. I don’t know if you can write it yourself. If you can't, just use the StringParser BBcode class.
PayPal payment system
You may know that PayPal provides a very good application programming interface (API) for those websites that want to set up a PayPal payment system on their website. The paypal IPN integration class component allows you to implement this function in 20 minutes.
Editor Controls
For me, the content of the website can be modified well using phpMyAdmin and a general text editor. But for my clients, they need a powerful WYSIWYG editor to help them work late. tinyMCE control written in javascript is such a component, using it can save you a lot of time.

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。
