| strstr | Added the optional parameter before_needle. | |
| strtotime | Prior to PHP 5.3.0, relative time formats supplied to the time argument of strtotime such as this week, previous week, last week, and next week were interpreted to mean a 7 day period relative to the current date/time, rather than a week period of Monday through Sunday. | |
