How to convert Chinese time and date into numbers in php

PHP is a scripting language often used for web development. In website development, date and time are very important elements. In this article, we will discuss how to convert Chinese time and date into numbers in PHP to meet different business needs.

1. Why do we need to convert Chinese time and date into numbers?

In many cases, we need to convert Chinese time and date into numbers, for example:

• The database requires the date and time to be stored in numeric format, which makes it easier to Perform calculations and comparisons;
• Websites need to use dates and times in forms, and these form elements can only accept input in numeric format;
• When performing data analysis, numeric formats are easier to process. Because they can perform various calculations, such as counting the amount of data within a certain period of time, average values, etc.

Therefore, converting Chinese time and date into digital format is very important to achieve the above business requirements.

2. Conversion method between Chinese time and date and numbers

In PHP, you can use the date and time function to convert Chinese time and date into digital format. The following are some commonly used functions:

2.1 strtotime() function

strtotime() is a very commonly used date and time processing function in PHP. It can convert any human-readable date string into a Unix timestamp, which is the number of seconds from January 1, 1970 00:00:00 GMT to the specified date-time.

For example, if you want to convert "September 13, 2022 14:30:00" into a Unix timestamp, you can use the following code:

$timestamp = strtotime("2022年9月13日14:30:00");
echo $timestamp;

The output will be: "1668397800" .

2.2 date() function

The date() function can format the timestamp into the required date and time format. When converting Chinese time and date into numbers, it is usually necessary to convert it into a Unix timestamp and then use the date() function to format it into a number format.

For example, if you need to convert "September 13, 2022 14:30:00" into the numeric format "20220913143000", you can use the following code:

$timestamp = strtotime("2022年9月13日14:30:00");
$number = date("YmdHis", $timestamp);
echo $number;

The output result will be: " 20220913143000".

3. Things to note

In the process of converting Chinese time and date into numbers, the following matters need to be considered:

3.1 Time format Must be consistent

Whether it is converted into Unix timestamp or date and time format, the format of Chinese time and date must be consistent. Otherwise, the conversion will not occur correctly.

3.2 Use an appropriate character set

If the Chinese time and date string contains special characters, such as Chinese characters, spaces, etc., you need to ensure that the character set used can handle these characters correctly. Otherwise, you may get incorrect results.

3.3 Consider the time zone

When converting Chinese time and date into digital format, you need to consider the impact of the local time zone. If the time being processed is UTC time, you can use the gmdate() function to convert it; if it is local time, you need to consider the impact of the time zone where the server is located.

4. Conclusion

In PHP, converting Chinese time and date into digital format is a very basic and common task. To ensure that the conversion results are accurate, every detail needs to be carefully considered and appropriate functions and methods used.
