PHP format local time date into integer

This article will explain in detail how PHP formats local time and date into integers. The editor thinks it is quite practical, so I share it with you as a reference. I hope you will finish reading this article. You can gain something later.

PHP Format local time and date into integers

To format the local time date into an integer, you can use the strtotime() function of php. This function converts the given datetime string to an integer in UNIX timestamp format representing the number of seconds elapsed since January 1, 1970 00:00:00 UTC.

grammar

int strtotime(string $timestamp)

parameter

• $timestamp: The date and time string to be converted. Can be in various formats, including:
  • "YYYY-MM-DD HH:MM:SS"
  • "YYYY-MM-DD"
  • "HH:MM:SS"
  • " 1 day"
  • "next Monday" etc.

return value

• Unix timestamp formatted as an integer. If the given string is invalid, FALSE is returned.

usage

To format a local time date as an integer, use the following steps:

1. Get the date and time to be converted.
2. Pass it to the strtotime() function.
3. Assign the return value to a variable.

Example

// Get the current local time
$datetime = date("Y-m-d H:i:s");

//Convert this to a UNIX timestamp
$timestamp = strtotime($datetime);

// Output UNIX timestamp
echo $timestamp;

This example will output the number of seconds elapsed since January 1, 1970 00:00:00 UTC.

Notice

• strtotime() The function takes the local time zone.
• If the given string is invalid, return FALSE.
• The converted UNIX timestamp is at risk of overflow because it is a 32-bit integer.

Other methods

In addition to the strtotime() function, there are other methods to format local time and date into integers:

• gmdate(): Get the timestamp in Greenwich Mean Time (GMT).
• gmmktime(): Creates a timestamp in Greenwich Mean Time (GMT).
• time(): Get the UNIX timestamp of the current time.

in conclusion

Use the strtotime() function to easily format a local time date into an integer representing the number of seconds elapsed since January 1, 1970 00:00:00 UTC.
