| 186 | All three would result in - Full name: jack city brown<br> |

| 187 | |
---|
| 188 | When you use this method of handling params you can secure your functions as well offer |
---|
| 189 | flexibility needed for both normal use and web services use. |
---|
| 190 | If you have params that are required just set the default as ##REQUIRED## |
---|
| 191 | Users of your functions can also use ##DEFAULT## to use your default value for a param |
---|
| 192 | when using the standard format like this: |
---|
| 193 | somefunc('jack','##DEFAULT##','brown'); |
---|
| 194 | This would result in - Full name: jack hick brown<br> |
---|
