How to get an echo of a multidimensional array?

Question

i got this Code:

$Wanteds[] = array(
                'WantedLevel' => 1,
                'WantedName' => "Nichtbefolgen",
                'WantedPreis' => 300
            );
$Wanteds[] = array(
                'WantedLevel' => 1,
                'WantedName' => "Beihilfe",
                'WantedPreis' => 200
            );
$Wanteds[] = array(
                'WantedLevel' => 2,
                'WantedName' => "Dealen",
                'WantedPreis' => 500
            );

Now, i tryed to get it into a variable:

echo "TESTING: $Wanteds[0][WantedName] <br />";

All i got it: TESTING: [WantedName] instead of: TESTING: Nichtbefolgen

Please keep in mind: I'm new to arrays and programming. :)

Depends on what you want.

Echo 1 value

echo "TESTING: " . $Wanteds[0]['WantedName'] . "<br />"; // possibility 1
echo "TESTING: {$Wanteds[0]['WantedName']} <br />"; // possibility 2

Print entire array

print_r($Wanteds); // Usefull for debugging and value checking

you have to warb the variable in strings with curly brackets

echo "TESTING: {$Wanteds[0]['WantedName']} <br />";

can you enable the errors in your page and see what happen error_reporting(E_ALL); ini_set('display_errors', '1'); – Osama Jetawe Nov 05 '15 at 09:19
Thanks for this snip! I got a lot of errors, okay, lets go on: – LuckyLuke Nov 05 '15 at 09:23
EDIT: I got the error, im calling echo bevor i created the array x) Thanks for your help! – LuckyLuke Nov 05 '15 at 09:24

No need to print variables in double quotes.

You can print it and concatenate it to string like this:

echo "TESTING: " .$Wanteds[0]['WantedName'] ."<br />";

Putting variables cause extra load on server as he needs to parse everything inside the string.

Above phenomena is called variable interpolation.

You can use strings without double quotes and that is faster than embedding them in double quotes.

Ah! So, i can use dot (.) to connect Strings or is this just for variables? – LuckyLuke Nov 05 '15 at 09:14
You can concatenate any number/string with dot. – Pupil Nov 05 '15 at 09:15
Just replaced my code with your example, it seems that the string is empty. Do i have another issue to mention? – LuckyLuke Nov 05 '15 at 09:16

To return the name that you want you can do the following :

echo "TESTING: " .$Wanteds[0]['WantedName'] ."<br />";

You could also display the whole array with :

print_r($Wanteds);

Or even display each sub-array separatly by doing :

foreach($Wanteds as $wanted){
 print_r($wanted);
}
