Returning values from a multidimensional array based using variable variables
and infinite key depth
I banged my head against this but could not find a way in language structure or
in functions to retreive a value from a multidimensional array where the key
path is known as a variable string. I considered some sort of recursive
function, but it seemed cumbersome for what should be a one-liner.
My solution uses eval() to return the array value:
<?php
$geolocation = array("ip"=>"127.0.0.1", "location" => array("city" =>
"Knoxville", "state_province" => "TN", "country" => "USA"));
print_r($geolocation); // Array ( [ip] => 127.0.0.1 [location] => Array (
[city]
=> Knoxville [state_province] => TN [country] => USA ) )
// typical use of variable variables
$key = "ip";
$result = $geolocation[$key];
print_r($result); // 127.0.0.1
$key = "location"; // another typical use of variable variables
$result = $geolocation[$key];
print_r($result); // Array ( [city] => Knoxville [state_province] => TN
[country] => USA )
// but how do we go deeper? this does NOT work
$key = "location['city']";
// $result = $geolocation[$key]; // Notice: Undefined index: location['city']
// print_r($result);
// this does NOT work
$key = "['location']['city']";
// $result = $geolocation{$key}; // Notice: Undefined index: ['location']
['city']
// print_r($result);
// this works:
$key = "['location']['city']";
$result = eval('echo $geolocation'."$key;");
print_r($result); // Knoxville
?>

I'm not sure I'm clear on the parameters of the bug you're trying to report.
Are
you saying you attempted to submit to the user contributed notes and received a
spam error? Can you provide the note you attempted to submit and email you used
(if any)? There are certain things that can trigger the spam filter and yours
may
have gotten caught there.
