Test script: --------------- var_dump( file_exists(sys_get_temp_dir()), is_writable(sys_get_temp_dir()), sys_get_temp_dir(), tempnam(sys_get_temp_dir(), 'php'), tempnam(sys_get_temp_dir(), 'aaa') ); Expected result: ---------------- bool(true) bool(true) string(34) "C:\Users\flip101\AppData\Local\Temp" string(45) "C:\Users\flip101\AppData\Local\Temp\php2EC.tmp" string(45) "C:\Users\flip101\AppData\Local\Temp\aaaF2A.tmp" Actual result: -------------- bool(true) bool(true) string(34) "C:\Users\flip101\AppData\Local\Temp" bool(false) string(45) "C:\Users\flip101\AppData\Local\Temp\aaaF2A.tmp" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=72317&edit=1
