[SOLVED] Print Array Key?

[JMair]

I'm not even sure i have the name correct, but I think it's called the array key.

 

$array[1]

 

I'm referring to the 1. (Array key?)

 

Anyhow. I have an array with each key named, and a variable assigned to each key of course. .

I would like to print just the array key in an echo line and I'm not sure where to look.

Like this?

 

$arr = Array( 'key1' => 'value', 'key2' => 'value');
echo implode(', ', array_keys($arr));

 

Output: key1, key2

 

Edit: That's easier, lol.

That is great! However I need to return on Key and not all. I've been tinkering around with it but can't seam to get it to echo 1 key.

 

$todo = array( 
"9AM" => "Wake Up.",
"10AM" => "Drink make hot tea.",
"11AM" => "Finish reading CNET news.",
);

 

So if I wanted to just echo a the Key value to Wake Up. I'm not sure how to do it.

It really depends on how you are using the array.

 

You might be looking for the array_search() function:

edit: nvm, use array_search()
