I'm trying to understand how the PHP `date_timestamp_get()` function works. I've come across this function while working on a project, but I'm having trouble grasping its concept and how to use it effectively. I have searched through the PHP documentation, but I'm still a bit confused.
Could someone please explain to me what the `date_timestamp_get()` function does and provide me with an example of how to use it correctly? I would greatly appreciate it if you could also provide some personal context or real-life scenarios in which this function would be useful.
Thank you in advance for your help!
