How do i echo the word 'Weapons' from this array?

PHP Code:

$shops = array("No such shop" => array(), "Weapons" => array(), "Food" => array(), "Toys" => array());
$shops[0]["type"] = "none";
$shops[1]["type"] = "weapon";
$shops[2]["type"] = "food";
$shops[3]["type"] = "toy";
$shops[0]["description"] = "Sorry this shop does not exist!";
$shops[1]["description"] = "Teach your pet(s) the art of self defence";
$shops[2]["description"] = "Yum!";
$shops[3]["description"] = "Every pet loves a new toy"; 


i tried

PHP Code:

echo $shops[1]; 


but it didn't work, is there a way, or is the array wrong?

A couple of things here. You are trying to declare your $shops array as associative given the index names "No such shop," "Weapons," etc. But then you make assignments using integer indices -- treating it as a sequential array. Try this code:

PHP Code:

<?php

$shops = array("No such shop" => array(), "Weapons" => array(), "Food" => array(), "Toys" => array()); 

$shops["No such shop"]["type"] = "none"; 
$shops["Weapons"]["type"] = "weapon"; 
$shops["Food"]["type"] = "food"; 
$shops["Toys"]["type"] = "toy"; 

$shops["No such shop"]["description"] = "Sorry this shop does not exist!"; 
$shops["Weapons"]["description"] = "Teach your pet(s) the art of self defence"; 
$shops["Food"]["description"] = "Yum!"; 
$shops["Toys"]["description"] = "Every pet loves a new toy"; 

?>

Now, you are not storing the term "Weapons" anywhere -- it is the string key to an associative array within $shops. To print it, you must assign it to a value of the array, not the key. For example, we are assigning "weapon" to $shops["Weapons"]["type"], so you could print it using that variable:

PHP Code:

print $shops["Weapons"]["type"]; 


how would i echo the word 'Weapons' in this example?

PHP Code:

<?php 

$shops = array("none" => array(), "Weapons" => array(), "none" => array(), "none" => array()); 

$shops["No such shop"]["type"] = "none"; 
$shops["Weapons"]["type"] = "none"; 
$shops["Food"]["type"] = "none"; 
$shops["Toys"]["type"] = "none"; 

$shops["No such shop"]["description"] = "none"; 
$shops["Weapons"]["description"] = "none"; 
$shops["Food"]["description"] = "none"; 
$shops["Toys"]["description"] = "none"; 

?>

I think he wants 'Weapons' and not 'weapon' in this case.

You can get the keys of an array using array_keys():

PHP Code:

print_r(array_keys($shops)); 


will result in:

Array (
  0=> "No such Shop",
  1=> "Weapons",
  2=> "Food",
  3=> "Toys"
)

So you can get Weapons from array_keys($shops)[1], but that doesn't really help, since if you knew the number was 1 you might as well just write "Weapons" on its own.

Since you are identifying your shops by name, without knowing in advance that you want the Weapons shop, you haven't got anything else with which to lookup the name.

i get the error

PHP Code:

Parse error: parse error, unexpected '[' 


when using print_r(array_keys($shops)[1]);

The print_r() was just meant to show what was in the array. Drop it and use echo or print:

PHP Code:

echo array_keys($shop)[1];

Should you not be using this code:

PHP Code:

echo array_keys($shop[1]); 


Steve.

With your way Oberon i get the same error, and with Gaffer Sports' it echos the word 'Array'.

ok try

PHP Code:

$keys = array_keys($shop);

echo $keys[1]; 


had to get all the way to the last post to see if that correction was going to be made

Oberon's example will get you "Weapons"
