+# FFXIV Icon Paths
+
+The path for icons are very funky, depending on the icon number you need to format the path very specifically, here is a function that does it in PHP which should be easy to translate into other languages:
+
+```php
+// Is the number 6 or more characters?
+$extended = (strlen($number) >= 6);
+
+// get icon based on number size, prepend 0 if its below 6 characters.
+$icon = $extended 
+  ? str_pad($number, 5, "0", STR_PAD_LEFT) 
+  : '0' . str_pad($number, 5, "0", STR_PAD_LEFT);
+  
+// build path, take values [0, 1, 2] from the number, add 000 for extended
+// for non extended start with 0 and add [1,2] + 000 for path.
+$path = $extended 
+  ? $icon[0] . $icon[1] . $icon[2] .'000' 
+  : '0'. $icon[1] . $icon[2] .'000';
+```
