ID: 52420 User updated by: php at calendee dot com Reported by: php at calendee dot com Summary: json_decode fails when underscores used in names -Status: Open +Status: Closed Type: Bug Package: JSON related Operating System: Mac OS 10.6.3, RHEL 5 PHP Version: 5.3.3 New Comment: I've actually solved this "bug". It's not a bug at all. The problem was that my json string repeated the same names several times. However, the values were not provided twice. So, when I renamed the "alarms_alarm_num" and "alarms_lsn" names to "alarmsalarmnum" and "alarmslsn", I was actually correcting the fact that those names were listed twice. Sorry for the bother. Previous Comments: ------------------------------------------------------------------------ [2010-07-23 22:13:23] php at calendee dot com Description: ------------ There appears to be a bug in json_decode(). In some cases, if there is an underscore in one of the names in a JSON string, json_decode fails to retrieve the value. If the underscore is replaced with nothing, json_decode properly retrieves the value. However, some names with underscores work properly.
