PHP - How to echo a value from mapped Array?

Question

I have a mapped Array named: $mapped

Below is a result of var_dump($mapped);

array(32) {
  ["Age: "]=> string(137) "21 Years. "
  ["Ethnicity: "]=> string(122) "Caucasian "
  ["Location: "]=> string(152) "Paris, France "
}

The problem is I don't get any results with: echo $mapped["Age: "];

I have tried:

echo $mapped["Age: "];           // No results
echo $mapped["Age:"];            // No results
echo $mapped[" Age:  "];         // No results
echo $mapped['Age: '];           // No results
echo $mapped['Age:'];            // No results
var_dump($mapped["Age: "]);      // result: NULL

What am I doing wrong? I want echo $mapped["Age: "]; to result: 21 Years

Thank you for your help

Why the colons at all? Get rid of them, use just regular words as keys... — Henrique Barcelos

Perhaps this is some space funkiness. Maybe there is more than one space that is swallowed by the browser? Make sure you copy & paste from the browser's source code view. (But what Henrique says applies too) — Pekka

string(137) "21 Years. " But there's significantly less than 137 characters. You probably are not seeing all of the spaces actually present, as @Pekka웃 says. — Waleed Khan

@HenriqueBarcelos @Pekka @Waleed: Thank you for your input. Why I have colons in array is cause I get this array with file_get_contents and surly I want to trim them. Now I found out why I cant echo and it was after looking at source code I found out that this Array have a LOT of HTML codes inside. How can I remove HTML codes from this Array? Should I use strip_tags how to use it? — Cyborg

Cybrog, white spaces are creating problem for you. Try the code below to remove the white space and access any element without any extra effort.

$keys = str_replace( ' ', '', array_keys($mapped) );
$values = array_values($mapped);
$mapped = array_combine($keys, $values); 
var_dump($mapped);

try this one to remove html

$keys = array_map("trim", array_map("strip_tags", array_keys($mapped)));
$values = array_map("trim", array_map("strip_tags", array_values($mapped)));
$mapped = array_combine($keys, $values); 
var_dump($mapped);

I guess you are right. It looks like a whitespace/space after colon signs. But now I copy pasted my source code to a NEW text document and the whitespace/space made NEW LINES. So it looks like space but is actually \n Please have a look at my question: stackoverflow.com/questions/19873071
