In laravel, sometimes it is necessary to convert strings to date format for date operations and calculations. Laravel provides a variety of methods to convert strings to dates. This article will introduce several of them.

1. Carbon class

Carbon is a PHP extension package that provides simple operations on date and time. The Carbon class is integrated by default in laravel and provides convenient methods for Carbon instantiation.

The method to convert a string to a date using the Carbon class is as follows:

$date = CarbonCarbon::createFromFormat('Y-m-d', '2022-06-20');
echo $date->format('Y-m-d H:i:s'); // 2022-06-20 00:00:00

In this example, we use the createFromFormat method to convert the string to a date and pass the parameter 'Y-m-d ' to indicate that this is a string in year-month-day format. After conversion, we can use the format method to format the date into the format we need. The format we output here is year-month-day hour:minute:second.

2. strtotime function

The strtotime function is a built-in function of PHP that can convert a string into a timestamp. We can use this timestamp to further manipulate dates.

The method of using the strtotime function to convert a string to a date is as follows:

$date = date('Y-m-d', strtotime('2022-06-20'));
echo $date; // 2022-06-20

In this example, we use the strtotime function to convert the string '2022-06-20' into a timestamp, and pass it to the date function to output the format we need.

It should be noted that the strtotime function is only applicable to some special formats, such as date strings in YYYY-MM-DD format. For date strings in other formats, we also need to use the createFromFormat method or write it ourselves. Analytic Functions.

3. Carbon Chinese

Carbon Chinese is a Chinese extension of the Carbon class, supporting the use of Chinese expressions to represent date and time. This is very convenient for some Chinese culture projects.

The method of using Carbon Chinese to convert a string to a date is as follows:

$date = CarbonChineseCarbonChinese::parse('2022年06月20日');
echo $date->format('Y-m-d H:i:s'); // 2022-06-20 00:00:00

In this example, we use the parse method of the CarbonChinese class to convert the Chinese date string 'June 20, 2022' 'Convert to date and use the format method to output the format we need.

It should be noted that the CarbonChinese package is a third-party extension package and needs to be installed in the project.

Summary

In laravel, there are many methods to choose from to convert strings to dates, and you can choose different methods according to project needs. It is more convenient to use the Carbon class, but for some special format date strings, it is recommended to use the createFromFormat method; use the strtotime function for date strings in some built-in formats; use Carbon Chinese for Chinese culture projects.
