Moving an associative array pointer by a known key
I have an associative array of lets say fruits and vegies:
array (apple => red, orange=> orange, celery=>green);
and I know the fruit / veggie and wanted to use the next() and prev() php functions.
Besides using a foreach loop, is there a way to move the array pointer to that key?
Thanks in advance

you can put the code into a for loop or a while loop, and determine the length of the array (count($array)) then you can utilize the next($array) to move the pointer forward or prev($array) to move backwards as you like.
you could just be like
$fruits = array (apple => red, orange=> orange, celery=>green);
echo $fruits['celery'];
and it will output green.
if you already know the fruit in question
any more I need more details on what you want.

no the only functions that move the internal array pointers are: end, prev, next, each, reset
All other operations on the array typical destroy/reset the internal array pointer

Thank you all for you work.
I plan on moving via prev, next, reset ... But would like to start in the middle of the array. If I am understanding you correctly hernst42, the only way to get to the middle will be using a foreach loop or something similar, then when I hit the key I can use the next and prev commands.
