Java is a very popular computer programming language, while PHP is another programming language widely used in web development. There are many datetime format conversion issues between Java and PHP. One of the problems that needs to be solved is the conversion of Java timestamps to PHP timestamps. In this article, we will explain how to convert Java timestamps to PHP timestamps.
Definition of Java and PHP timestamp
Java timestamp is a long value that represents the approximate number of milliseconds that have passed since "January 1, 1970, 00:00:00 GMT" . Java timestamps can be obtained using the System.currentTimeMillis() method.
PHP timestamp is also an integer value that represents the approximate number of seconds that have elapsed since January 1, 1970, 00:00:00 GMT. PHP timestamps can be obtained using the time() function.
Convert Java timestamp to PHP timestamp
Converting Java timestamp to PHP timestamp requires understanding the differences in how time is represented between the two languages. Java timestamps are expressed in milliseconds, while PHP timestamps are expressed in seconds. So before converting Java timestamp to PHP timestamp we need to divide timestamp in Java by 1000 to convert it from milliseconds to seconds.
The following is a sample code to convert Java timestamp to PHP timestamp:
Java code:
long javaTimestamp = System.currentTimeMillis();
int phpTimestamp = (int)(javaTimestamp / 1000);
PHP code:
$phpTimestamp = time();
The above example code converts Java timestamp to PHP timestamp The code logic is the same. Just divide the Java timestamp by 1000 and convert it to a PHP integer value.
It should be noted that time zone may cause problems when converting timestamps. Timestamps in Java and PHP use the UTC time zone by default. If you need timestamp conversion in other time zones, use the corresponding time zone conversion method.
Conclusion
In this article, we introduced how to convert Java timestamps to PHP timestamps. Java and PHP represent time differently, so you need to be aware of this difference when converting Java timestamps to PHP timestamps. If you need timestamp conversion in other time zones, use the corresponding time zone conversion method. Hope this article can be helpful to you.
