Array question...sorry I'm new to PHP

Hello I'm new to PHP and really enjoy the learning experience and support for the same that I have been able to find. I'm currently working on a web page for my baseball league and have come up to a snag. I have tried to get support from several forums and I'm currently trying their suggestions. I have noticed the abundance of array functions available for a person to use, however, there is one I don't seem to see. For my web page I have created a 2-dimensional array to sort all of the teams (keys) schedule data, wins, losses, ties, etc.etc. The last thing I do is create a win% for each team then insert the values into a column. In the event 2 or more teams have equal winning percentages I have created an additional array to keep tract of each teams head to head results (based on wins only). So finally my question, is there a simple array function to simply swap two key/value pairs in the array. In this example row 3 becomes row 2 and row 2 becomes row 3 (based on a condition/comparison)? Thank-you for your time and patience.
