Question

I suspect that this has been asked before, but I have no idea what it’s actually called, so I couldn’t find anything.

I am creating a browser based game in which the player has a 10×10 grid. Each grid square has a few aspects to it, some as binary flags and other as hex values.

To store this information in an array, I want a given cell to contain the following:

“9A0101” where 9A is the tile type, and the 0s and 1s are binary flags about that map tile.

I want to be able to take “9A0101” and split it into “9A”, “0”, “1”, “0”, and “1” as separate variables.

TLDR:

How do I slice up a string in PHP? The string will always be the same length, and the parts where I want to cut it will always be at the same offsets.

Answer 1

what about substr() ? :

<?php
$str = '9A0101';
echo substr($str,0,2); 
echo substr($str,2,1); 
echo substr($str,3,1);
echo substr($str,4,1); 
echo substr($str,5,1); 
?>
