Array Key Confusion

I should say, make a test.php file and try it yourself!. But let's say that a value will be overwritten...

<?php $products[]="red"; $products[10]="blue"; $products[15]="green"; $products[]="yellow";

echo $products[]; ?>

This is my test file. How can i echo yellow here???

Use var_dump($products) and you will see.. .:)

But it will be 16

<?php $products[]="red"; $products[10]="blue"; $products["aa"]="green"; $products[0]="yellow";

echo $products[0] ; var_dump($products); ?>

Var_dump is not showing anything about red?

It does here. It shows 0.

It does not show. Zero is for yellow. I want to echo red.

But when i wrote $products[]=""; in the starting it shows correctly...Why is it so???

-sigh-

Because you changed your code in your opening post and ind your example.

But lets go again

<?php 
$products[]="red"; $products[10]="blue"; $products["aa"]="green"; $products[0]="yellow";

echo $products[0] ; var_dump($products); 
?>

first 0=.>red. then 10=>blue then aa=>green but then you OVERWRITE 0 to yellow.

So when var_dump or echoing. products[0] is"yellow".

Then how can i echo red here?

Do you even read what i answer to you?

"but then you OVERWRITE 0 to yellow."

So red is not there anymore. The array 0 has become yellow.

This means red is no longer existed anywhere?

... Yes i said that. If you overwrite something.. the original thing is gone. So red is gone. Forever.
