mktime这个括号里的参数什么意思啊 看不太懂也看手册了,该怎么处理
mktime这个括号里的参数什么意思啊 看不太懂也看手册了
mktime(0, 0, 0, date('m'), date('d'), date('Y'));
------解决方案--------------------
int mktime ([ int $hour [, int $minute [, int $second [, int $month [, int $day [, int $year [, int $is_dst ]]]]]]] )
手册说的很清楚了,六个整形参数 时、分、秒、月、日、年,参数可从右向左省略,省略的默认为当前值
你的代码返回当天凌晨的时间戳,其实后面三个参数都可以省略了

When developing using PHP programs, you often encounter some warning or error messages. Among them, one error message that may appear is: PHPWarning:date()expectsparameter2tobelong,stringgiven. The error message means: the second parameter of the function date() is expected to be a long integer (long), but what is actually passed to it is a string (string). So, we

If you're looking for a way to automatically create and name files and folders based on system timestamps, you've come to the right place. There is a super simple way to accomplish this task. The created folders or files can then be used for various purposes such as storing file backups, sorting files based on date, etc. In this article, we will explain in some very simple steps how to automatically create files and folders in Windows 11/10 and name them according to the system’s timestamp. The method used is a batch script, which is very simple. Hope you enjoyed reading this article. Section 1: How to automatically create and name a folder based on the current timestamp of the system Step 1: First, navigate to the parent folder where you want to create the folder,

Detailed explanation of the method of converting int type to byte in PHP In PHP, we often need to convert the integer type (int) to the byte (Byte) type, such as when dealing with network data transmission, file processing, or encryption algorithms. This article will introduce in detail how to convert the int type to the byte type and provide specific code examples. 1. The relationship between int type and byte In the computer field, the basic data type int represents an integer, while byte (Byte) is a computer storage unit, usually 8-bit binary data

In C++, variables of type int can only hold positive or negative integer values; they cannot hold decimal values. There are float and double values available for this purpose. The double data type was created to store decimals up to seven digits after the decimal point. Conversion of an integer to a double data type can be done automatically by the compiler (called an "implicit" conversion), or it can be explicitly requested by the programmer from the compiler (called an "explicit" conversion). In the following sections, we'll cover various conversion methods. Implicit conversions The compiler performs implicit type conversions automatically. To achieve this, two variables are required - one of floating point type and the other of integer type. When we simply assign a floating point value or variable to an integer variable, the compiler takes care of all the other things

The value range of int32 is from -2 to the 31st power to 2 to the 31st power minus 1, that is, -2147483648 to 2147483647. int32 is a signed integer type, which means it can represent positive numbers, negative numbers, and zero. It uses 1 bit to represent the sign bit, and the remaining 31 bits are used to represent the numerical value. Since one bit is used to represent the sign bit, the effective number of int32 bits is 31.

How to get millisecond representation of date using getTime() method of Date class In Java, Date class is a class used to represent date and time. It provides many useful methods to manipulate and obtain information about date objects. Among them, the getTime() method is an important method in the Date class, which can return the millisecond representation of the date object. Next, we will detail how to use this method to obtain the millisecond representation of a date, and provide corresponding code examples. Using the Date class

1. Introduction The Date class in the java.util package represents a specific time, accurate to milliseconds. If we want to use our Date class, then we must introduce our Date class. Writing the year directly into the Date class will not produce the correct result. Because Date in Java is calculated from 1900, so as long as you fill in the first parameter with the number of years since 1900, you will get the year you want. The month needs to be subtracted by 1, and the day can be inserted directly. This method is rarely used, and the second method is commonly used. This method is to convert a string that conforms to a specific format, such as yyyy-MM-dd, into Date type data. First, define an object of Date type Date

The number of bytes occupied by the int type may vary in different programming languages and different hardware platforms. Detailed introduction: 1. In C language, the int type usually occupies 2 bytes or 4 bytes. In 32-bit systems, the int type occupies 4 bytes, while in 16-bit systems, the int type occupies 2 bytes. In a 64-bit system, the int type may occupy 8 bytes; 2. In Java, the int type usually occupies 4 bytes, while in Python, the int type has no byte limit and can be automatically adjusted, etc.
