I have an array defined:
$flatdata["body_font-family"] = "Arial";
I want to use that array value in a function:
function display_name($input) {
showmethekeyofthearrayvalue($input); // how can I get the key name here?
}
echo display_name($flatdata["body_font-family"]);
So that the output is:
body_font-family
You may try like this:
key($arr);
This will return the key name
From the manual
key() returns the index element of the current array position.
Or you may try to use array_search
$arr = array ('key1' => 'a', 'key2' => 'b', );
$key = array_search ('a', $arr);
What about this?
function display_key($array, $val) {
while($array_pos = current($array)) {
if($array_pos == $val) {
return key($array);
}
}
}
echo display_key($flatdata, $flatdata["body_font-family"]);
I'm assuming displaykey is supposed to be display_name in your example.
If so, you won't be able to return the key by passing in an array element such as $flatdata["body_font-family"] because in this case you're only passing in a specific string i.e. Arial, so the function doesn't have any info about the key.
