how do i access the contents of this array using PHP?

the above was a var_dump($info)

Answer 1

You can use either the numeric or the associative key:

echo $array[0]; // outputs 1
echo $array["id"];  // outputs 1

I'm guessing this is the result of a mysql_fetch_array() operation, isn't it? You may want to specify whether you want a numeric or associative array using the second parameter to that function.

Example:

$record = mysql_fetch_array($query, MYSQL_ASSOC);  // for associative keys only
$record = mysql_fetch_array($query, MYSQL_NUM);    // for numeric keys only

Answer 2

It depends on which part of the array you are trying to access.

If you are trying to access a specific item, you can access it by its index ; for instance :

echo $info['passwordID'];

Should give you :

myPassword

(edit after the comment)

For the email address, there is this portion in your var_dump's output :

["emailAddress"]=>
  string(24) "[email protected]"

This indicates that the e-mail address is stored in the array as an element that has the key "emailAddress".

Which means you should be able to get that e-mail address like this :

echo $info['emailAddress'];

And as you also have this portion of text in the var_dump's output :
(About that duplication of data, you should read Pekka's answer, who provides an idea of why your data is in your array twice, with both integers and strings as keys)

[3]=>
  string(24) "[email protected]"

You could also use :

echo $info[3];

(of course, in each of those cases, you could also store this to a variable for futures re-use)

Another solution, if you want to access each item, would be to use some foreach loop ; for instance :

foreach ($info as $key => value) {
    echo "Value for key $key is $value <br />";
}

You might want to go through the arrays section of the PHP manual, for more informations.

And, also, the section about array functions.

Answer 3

The array appears to have both string and numeric keys. You can access the fields using the array index operator []. Supply either the numeric key or the column name:

echo $info['UserID']; // output "myUserName"
echo $info['emailAddress']; // output "[email protected]"

Answer 4

if $info is the array, then you can echo $info[6] for example.
If you want it as a string then $s=print_r($info,true);

It seems you are doing some thing wrong, as there shouldn't be a need to access array like that, and there other ways to access objects as arrays.
