Re: How To Use The next() and prev() functions on multi-dimensional arrays

Multi-dimensional arrays work the same as non-nested arrays. You just need to look at how to access them the same. For example: Next ($cat_data); versus: Next ($cat_data[0]); or even: $row =& $cat_data[1]; //notice the use of a reference & (to keep from using a copy) Next ($row); Well, have fun ...

Hello Everyone, I have a multi-dimensional array called $cat_data, and I need to access certain elements in the array using the next() and prev() functions. I did consider using loops like for, foreach, and while...but for this particular application, I don't want to loop through the entire array. Also, I need everything in that array, so no I don't want to limit the data drawn from the database. I know the two above mentioned functions work with normal arrays, but how would I make it work with multi-dimensional arrays? The following is a little idea of the structure of the array: $cat_data[$a][$b] where $a is the row number from the database, and $b is the column being accessed. $cat_data[0][0] = the first row of the id column. $cat_data[0][1] = the first row of the name column.
