Issue accessing elements of nested associative array
So I have some data that's coming back from a database query, and the resulting array (gotten with print_r) looks like this (it's assigned to a var called $locationData):
Array
(
[0] => Array
(
[id] => 1
[location_name] => Cook Minnesota
[location_lat] => 47.72037
[location_long] => -90.32667
)
[1] => Array
(
[id] => 2
[location_name] => Lake Minnesota
[location_lat] => 47.18238
[location_long] => -91.35301
)
[2] => Array
(
[id] => 3
[location_name] => St. Louis Minnesota
[location_lat] => 46.83572
[location_long] => -91.96299
)
)
I have a foreach loop that needs to grab the location_name from each. It looks like this:
foreach ($locationDa开发者_如何学Pythonta as $location => $value ) {
echo '<p>name ' . $location['location_name']. '</p>';
}
I'm 99% certain this should work; it's basically the same code I've used a dozen times before. But the echo is not returning anything - not even the static text (<p>name
). It's not throwing any errors, and if I try to do a print_r($location), I get nothing.
Any ideas? I'm sure it's something really simple.
You want $value['location_name']
because $value
represents the arrays while $location
represents the indexes of the arrays:
echo '<p>name ' . $value['location_name']. '</p>';
It is:
foreach ($locationData as $location => $value ) {
echo '<p>name ' . $value['location_name']. '</p>';
}
