Wrong order: setlocale(LC_TIME,'en_US.UTF-8'); setlocale(LC_CTYPE,'en_US.UTF-8'); strftime('%Z'); Right order: setlocale(LC_CTYPE,'en_US.UTF-8'); setlocale(LC_TIME,'en_US.UTF-8'); strftime('%Z'); Error is notice in alle php 7+ version (5.6 doesn't had this issue) tested version: 5.6.35 (no issue here) ,7.0.29, 7.1.16, 7.2.4, 7.2.5 Test script: --------------- <?php $value = strftime('%Z'); echo $value.'%Z'; echo '<br>'; setlocale(LC_TIME,'en_US.UTF-8'); $value = strftime('%Z'); echo $value.'%Z'; echo '<br>'; setlocale(LC_CTYPE,'en_US.UTF-8'); // here came the crash in the next line $value = strftime('%Z'); echo $value.'%Z'; echo '<br>'; Expected result: ---------------- Result should be that it behavior in the same as when you run %z. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76307&edit=1
