PHP is an open source scripting language executed on the server side. It is a commonly used website programming language and is mainly suitable for Web development; however, it does not mean that PHP can only be used for Web development.
In addition to web development, PHP can also:
1. Use PHP to write crawlers, automated operation and maintenance, embedded, desktop application development, and APP development.
2. PHP can be used as a command line scripting language, replacing shell, python, ruby, perl, etc.
3. Do GUI, such as php-gui, PHP-GTK
4. WeChat development
5. Do system auxiliary development
PHP has There are many unsuitable application scenarios (computing intensive), such as operating system development and database engine development; but PHP can assist in the development of these systems. For example, use PHP to develop a phpMyAdmin to visually manage the database MySQL; for example, develop a "phpLinuxAdmin" to manage a Linux server without a graphical interface.

php怎么把负数转为正整数Apr 19, 2022 pm 08:59 PMphp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”。
php怎么实现几秒后执行一个函数Apr 24, 2022 pm 01:12 PM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字符串有没有下标Apr 24, 2022 am 11:49 AMphp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怎么除以100保留两位小数Apr 22, 2022 pm 06:23 PMphp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。
php怎么根据年月日判断是一年的第几天Apr 22, 2022 pm 05:02 PM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。
