arrays
 

is there a function that will shift its values to different indecies?for example:

myarray = Array();
myarray[0] = 0;
myarray[1] = 1;
myarray[2] = 2;
myarray[3] = 3;

can be changed to:

myarray[0] = 1;
myarray[1] = 2;
myarray[2] = 3;
myarray[3] = 0;

thanks

array_shift and array_push should do this for you. The first will shift your elements up one, with the first element falling off the top of the list. Then array_push, can be used to push that element back on at the bottom.

In fact, PHP has a dizzying set of array functions:
