I need to generate a unique ID in php based on current date and time to keep a log of when i am running code. i.e. every time i run the code it should be able to generate a unique id based on current date and time.
Hope I am clear with my ques. How to do that?

Using time() to create sortable unique id's
Concatenating strings will also further randomize your desired result and still keep it sortable. manual here
$uniqueId= time().'-'.mt_rand();
다른 팁
You can use a combination of uniqid()
and time()
like so:
$s = uniqid(time(), true);
Example output:
1346136883503c6b3330caf5.19553126
Is this what you're looking for? uniqid()
From the doc:
Gets a prefixed unique identifier based on the current time in microseconds.
