A simple array-like PHP class for using constants in strings
------------------------------------------------------------

In PHP, if you want to use a constant in a string, you have a few options.

You could use the concatenation operator:

```
define('COLOR_RED',    0);
define('COLOR_GREEN',  1);
define('COLOR_BLUE',   2);

echo "SELECT * FROM shirts WHERE color IN (".COLOR_RED.",".COLOR_GREEN.",".COLOR_BLUE.")";
```

or use good ol' `sprintf()`

```
define('COLOR_RED',    0);
define('COLOR_GREEN',  1);
define('COLOR_BLUE',   2);

echo sprintf(
	'SELECT * FROM shirts WHERE color IN (%d, %d, %d)',
	COLOR_RED,
	COLOR_GREEN,
	COLOR_BLUE
)
SQL;
```

or you even assign the constants to a variable:

```
define('COLOR_RED',    0);
define('COLOR_GREEN',  1);
define('COLOR_BLUE',   2);

$COLOR_RED   = COLOR_RED;
$COLOR_GREEN = COLOR_GREEN;
$COLOR_BLUE  = COLOR_BLUE;

echo
