How to convert timestamp to integer in PHP

The timestamp in PHP is an integer form representing time, usually the number of seconds that have passed since the first year of Unix (January 1, 1970 00:00:00 GMT) . In programming, we often need to convert timestamps into other forms of integers. Here we will introduce how to convert PHP timestamps into integers, as well as specific code examples.

In PHP, we can use the strtotime() function to convert a time string into a timestamp, and then use the date() function to convert the timestamp into a specific date format. To convert the timestamp into an integer, we can achieve it through the following methods:

1. Directly use the intval() function

$timestamp = time(); // Get current timestamp
$integer_timestamp = intval($timestamp);
echo $integer_timestamp;

2. Use forced type conversion

$timestamp = time(); // Get the current timestamp
$integer_timestamp = (int)$timestamp;
echo $integer_timestamp;

3. Use type conversion function

$timestamp = time(); // Get the current timestamp
$integer_timestamp = (integer)$timestamp;
echo $integer_timestamp;

The above three methods can convert the PHP timestamp into integer form for operations in other places in the program that need to use integer form. In actual applications, just choose one of the methods for conversion according to specific scenarios and needs.

Hope the above introduction and examples can help you understand the method of converting PHP timestamp to integer. Good luck with your programming!
