Converting UNIX Timestamps to Formatted Date Strings in PHP

In PHP, the gmdate function can be utilized to convert UNIX timestamps into date strings in a specific format. This function takes two arguments: the date format string and the timestamp to be converted.

To achieve the desired format of "2008-07-17T09:24:17Z", the following date format string can be used: "Y-m-d\TH:i:s\Z". The Z specifier indicates that the date should be represented in the ISO 8601 format, which includes a "Z" suffix to denote Coordinated Universal Time (UTC).

For example, to convert the timestamp 1333699439 to the desired format, the following code can be used:

This code will output the date string "2008-07-17T09:24:17Z", as requested.
