Edit report at https://bugs.php.net/bug.php?id=79246&edit=1 ID: 79246 User updated by: tiruchi_eral at outlook dot com Reported by: tiruchi_eral at outlook dot com Summary: str_repeat breaks due to limit on argument Status: Not a bug Type: Bug Package: *General Issues PHP Version: 7.4.2 Block user comment: N Private report: N New Comment: correction to test script to make the post coherent, can't edit original post. please fix this. <?php $n = 1_000_000_000_000; $s = "abab"; print_r(str_repeat($s, $n) ); ---- Thanks for comment. I apologize for being rude, ignorant , etc. and especially for the error in test script. Again I apologize since I might be forsaking this issue for the foreseeable future. And not posting what I intended to due to reasons beyond my control. Sorry.

Arbitrary precision can't help that. Solution hint: If the desired prefix length was 4 then the answer would be 2, right? What if the prefix length was 8? ------------------------------------------------------------------------ [2020-02-08 08:19:14] tiruchi_eral at outlook dot com arbitrary precision data type would solve this. like poorly named Integer in Haskell. In my defence before I forget, among a long list of other things, I tried enabling gmp extension and using gmp_abs to create what was required, it didn't work. gmp doesn't have a alternative for str_repeat, same for bcmath. Closing this, as I am not sure if php has something for this somewhere OOB. enabling php extensions doesn't count as OOB, and is not easy due to poor official documentation. My goal was to complete a program quickly for solving(https://www.hackerrank.com/challenges/repeated-string/problem), without implementing orthogonal stuff. apologies if I made any errors in reporting this issue or any other errors in general. ------------------------------------------------------------------------ [2020-02-08 07:50:18] tiruchi_eral at outlook dot com Description: ------------ --- From manual page: https://php.net/function.str-repeat --- Test script: --------------- <?php $n = 1_000_000_000_000; $s = "abab"; print_r(repeatString($s, $n) ); Expected result: ---------------- see the string repeated $n times.
