@access
Usage scope: class, function, var, define, module
This tag is used to indicate the access permission of the keyword: private, public or protected
@author
Specify the author
@copyright
Scope of use: class, function, var, define, module, use
Indicate copyright information
@deprecated
Scope of use: class, function, var, define, module, constent , global, include

@example
This tag is used to parse a section of file content and highlight them. Phpdoc will try to read the file content from the file path given by this tag@const
Usage scope: define
Used to specify the constant of define in php
@final
Usage scope: class, function, var
Indicates that the keyword is a final class, method, attribute, and prohibits derivation and modification.
@filesource
Similar to example, except that this tag will directly read the content of the currently parsed php file and display it.
@global
Indicate the global variable referenced in this function
@ingore
Used to ignore the specified keyword in the document
@license
Equivalent to the
html tag The in is the URL first, followed by the content to be displayed For example, Baidu
Can be written as @license http://www.baidu.com Baidu
@link
Similar to license
but you can also point to any keyword in the document through link
@name
Specify an alias for the keyword.
@package
Usage scope: page level -> define, function, include
Class level ->class, var, methods
Used to logically combine one or several keywords Assigned to a group.
@abstrcut
Indicates that the current class is an
abstract class @param
Specifies the parameters of a
function @return
Specifies a The return pointer of a method or function
@
static indicates that the keyword is static.
@var
Indicate the variable type
@version
Indicate the version information
@todo
Indicate the areas that should be improved or not implemented
@throws
Indicate that this function may Error exceptions thrown, extreme situations
As mentioned above, ordinary document tags must be marked with @ at the beginning of each line. In addition, there is also a tag called inline tag, using {@} Representation, including the following:

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。
