I have a 2D array as illustrated below:
|1|2|3|
|4|5|6|
I'm trying to prepend a column to it as illustrated below:
|X|1|2|3|
|X|4|5|6|
Using array_unshift will cause the elements to become shuffled and I need them to be retained. I also tried array_merge as well as "adding" the new column with the existing array.
I'm wondering what's the best way to accomplish this?
