 Dude... Read up on generating random strings in php na.. You can use arrays or substr function for the alphabets, rand function for the numbers |

A better approach will be to use only numbers instead. Because if you use two first alphabets, the probability of uniqueness will be a-z.. And for the middle numbers will only be unique to its placeholder domain(ie, 4000056 can only accomodate 1000000 - 4000056)... If you are on facebook try to download a photo on your news feed, it will have a file name like : 1508866654_5524343664_55600545_n.jpg . The numbers in this name was generated by a unique id generation system built by facebook..Twitter has open-sourced theirs with an API(search google for snowflake). I have also built one(Want to use it for a project) but it is copyrighted for now. |

Nairaland is popular for this! You hardly get answers here. I ain't doing better sha since a I am not in the mode of providing answers. My advise search stackoverflow.com if you are unable to find an answer you can ask them there. |

Function generateId ( ) { $rand_four_digits = rand(1000, 9999); $aphabets = array("A",.... "Z"  ; //list A to Z//you generate a random alphabet using $random_index = rand(0, 25); $random_alphabet = $alphabets[$random_index] ; //you can then generate more and concatenate $generated_id ="whatever" ; return $your_generated_id; } I'd suggest doing it in at least 3 different ways so you can learn |
