Address breaks map display, why?

Currently I am generating a Google static map by inserting an address through PHP insertion like this:

<img src="http://maps.googleapis.com/maps/api/staticmap?center=<?=$gmapadd?>&zoom=14&size=300x200&markers=color:blue|label:A|<?=$gmapadd?>&sensor=false">

Now here is an example output from this same script that displays properly:

<img src="http://maps.googleapis.com/maps/api/staticmap?center=11555+Central+Parkway+Jacksonville+FL+32224&amp;zoom=14&amp;size=300x200&amp;markers=color:blue|label:A|11555+Central+Parkway+Jacksonville+FL+32224&amp;sensor=false">

Here however, the output/address breaks the API (doesn't report an error, it just doesn't show the map), but I don't see the formatting problem or why it would break the map display. Also, if I enter this address into Google maps 5000-18 Hwy 17 #82 Orange Park, FL 32003 it does recognize it and display properly?

<img src="http://maps.googleapis.com/maps/api/staticmap?center=5000-18+Hwy+17+#82+Orange+Park+FL+32003&amp;zoom=14&amp;size=300x200&amp;markers=color:blue|label:A|5000-18+Hwy+17+#82+Orange+Park+FL+32003&amp;sensor=false">

Solution

The "#" is not legal in a URL. It needs to be encoded:

http://maps.googleapis.com/maps/api/staticmap?center=5000-18%2BHwy%2B17%2B%2382%2BOrange%2BPark%2BFL%2B32003&zoom=14&size=300x200&markers=color:blue|label:A|5000-18%2BHwy%2B17%2B%2382%2BOrange%2BPark%2BFL%2B32003&sensor=false
