echoing array values

hiflyerx

so if I have

$camera_routes = array (
    "N_down_DF_in_on_Memorial"     =>array(42, 17,30, 33, 36, 32, 34),
	"NW_down_CROW"                 =>array(29, 37, 16, 4, 35, 5),
	"NW_down_14th"                 =>array(39, 35, 5)
);

//lets show the routes

for ($i=0; $i<=count($camera_areas)-1; $i++) {

echo $camera_areas[$i];
}

How do I echo $camera_routes to get the first set of values - the descriptions?

"N_down_DF_in_on_Memorial"
"NW_down_CROW"
"NW_down_14th"

Much Thanks,

An array of $camera_routes's keys (the descriptions) can be got with [man]array_keys[/man].

Much Thanks, but this gives me:

Array
(
[0] => N_down_DF_in_on_Memorial
[1] => NW_down_CROW
[2] => NW_down_14th
)

What if I just wanted:
N_down_DF_in_on_Memorial
NW_down_CROW
NW_down_14th

I'm trying to get this:

<form id="form1" name="form1" method="post" action="">
  <label>Routes:
  <select name="Routes" id="Routes">
    <option value="1">N_down_DF_in_on_Memorial</option>
    <option value="2">NW_down_CROW</option>
    <option value="3">NW_down_14th</option>
  </select>
</label>
</form>

Again MUCH thanks - I'm a bit of a n00b, so I appreciate the help!

hiflyerx

Yeah, i don't understand why
$camera_areas[0]
wouldn't give me
N_down_DF_in_on_Memorial

or
$camera_areas[0,0]
wouldn't return 42

I hope you understand where I'm coming from!

Again, thanks for the help!

Don't use print_r.

foreach($camera_routes as $route) echo $route,"\n"; // Or <br> or whatever you want on each line as well as the description itself.

Yeah, i don't understand why
$camera_areas[0]
wouldn't give me
N_down_DF_in_on_Memorial

Because "N_down_DF_in_on_Memorial" is a key in the $camera_areas array, and $camera_areas[0] would return the 0th value.

or
$camera_areas[0,0]
wouldn't return 42

Apart from it being invalid syntax, $camera_areas is not a two-dimensional array; it's a one-dimensional associative array.

More on how arrays work can be found in the manual in the section on the array type.

Yeah, it's recognised that newbies need additional help over more experienced coders, which is why there is a forum dedicated to them.

thanks for the help - I'll stick to the newbie forum from here out 😉

google took me here....

Only while you still consider yourself a newbie, of course (unless you want to stick around and help other newbies!). Many started out there asking questions and have since migrated to helping others in the other forums.
