How to generate such a set of data to see other people generate a set of random numbers, the time is different, don't know how to achieve: 2258083390017B2258083580030B225808437601E022580844800166 very close to the two groups: how does 2258086181028E22 generate such a group of data?
When we see that others generate a set of random numbers with the same time, we don't know how to implement them:
2258083390017B
2258083580030B
225808437601E0
22580844800166
Two groups with very short time:
2258086181028E
225808618102B5
Does anyone know what the data is? thank you.
------ Solution --------------------
Divided into two parts
The previous part is the timestamp.
The following part is a random character.
Do you know you want to meet the requirements of the landlord?
------ Solution --------------------
The timestamp can also be increased.

The first 10 digits add a value to the timestamp.
Hexadecimal representation of the last four characters in milliseconds
Basically this form
$k = 887654321;
$t = explode(' ', microtime());
printf('%u%04X', $t[1]+$k, $t[0]*1000);
