It doesn't work as it should with multiple encodings since it is implemented. ------------------------------------------------------------------------ [2018-08-04 00:13:05] smokey101stair at gmail dot com Description: ------------ The function mb_detect_order() can receive either a comma separated list of encodings or an array of encodings. However, its return value varies based on whether it is given a string or an array that contain the same values. Test script: --------------- https://3v4l.org/gJfAO Expected result: ---------------- mb_detect_order() should return the same value regardless of which type is used for the encoding_list parameter. HHVM seems to not be affected by this. Actual result: -------------- When given a string, mb_detect_order() will return true if it finds at least one supported encoding in the list. When given an array, mb_detect_order() will return false if it finds any non-supported encoding. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76704&edit=1
