Array....

[djoseph74]

Hi,

When foreach looping thru an array $build that I created, I noticed two values that seem to be in each one. value x and value y. These appear to be values that PHP places in each array. Could someone explain to me what they mean, how can I get rid of them?

They mean x and y are in the array. You can use unset to get rid of them. What are you talking about???

Let me see if I can explain better.

I have built an array with 4 values:

$build["username"]
$build["password"]
$build["firstname"]
$build["lastname"]

I now pass it to an object:

$admin->add_user($build);

now, in the function add_user:

function add_user ($form) {
foreach ($form as $name => value) {
echo "$name => $value<br>";
}
}

the display output is:

username => djoseph74
password => password
firstname => Dan
lastname => Joseph
x => 7
x => 3

I have no idea where the x and y came form, and did not assign them to the array.

Does that make more sense? Any ideas? Anyone?

It sounds like you unintentionally reused a global variable ("$build") that was already in your namespace.

The first thing I'd try is changing the name of the variable to something less common (e.g. "$nameBuild").

Hi,

ahh... That made me think of something else. $build is being built by a foreach of $POST, and inside there appears to be x and y. PHP must create that automatically inside the $POST. I was just simply passing them on to $build.

Now, any idea what x and y mean inside $_POST? 🙂

Don't know, unless you have fields with those names on your form.

Try adding a call to phpinfo() and see if it sheds any light on it. 😕

PHP doesn't add anything to your post array, you're getting those keys and values from either your form, or a global var with the same name .. .

oh ok, you know, that would make sense. The application sets about 35 session variables (yes, I know...but I didn't do it...), and I'm reassigning those variables... I'll have to unset the ones that I want to reassign values too. Thanks man!
