Previous Comments: ------------------------------------------------------------------------ [2019-07-12 15:08:37] mishamosher at gmail dot com I confirm that this issue is no longer present in PHP 7.2.20 for my environment. ------------------------------------------------------------------------ [2019-07-12 15:04:10] nikic@php.net I want to check back whether this issue still exists in PHP 7.2.20. The 7.2.19 release had some serious issues with opcache and it may be that this is a side-effect of the same problems. ------------------------------------------------------------------------ [2019-06-04 21:59:49] cmb@php.net Related To: Bug #78106 ------------------------------------------------------------------------ [2019-06-04 17:59:21] mishamosher at gmail dot com Hello cmb@php.net, Results with OPCache on: string(6) "2f6573" string(2) "ff" Results with OPCache off: string(6) "2f6573" string(2) "2f" ------------------------------------------------------------------------ [2019-06-04 09:02:49] cmb@php.net Please run the following variation of your script, and report the results: <?php $in = "/es"; $out = substr($in, 0, 1); var_dump(bin2hex($in), bin2hex($out)); ?> ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
