Bug #52420 [NEW]: json_decode fails when underscores used in names

From: Operating system: Mac OS 10.6.3, RHEL 5 PHP version: 5.3.3 Package: JSON related Bug Type: Bug Bug description:json_decode fails when underscores used in names 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.
