replace array items with other items

hopefully simple question!

[HelenDev]

I have an array e.g.

$fruit= array("apple", "orange", "pear");

and I want to replace one value with another, say orange with banana, and keep the order (keys) of the array the same.

I'm sure this should be simple but I just can't fathom it!

>>$fruit= array("apple", "orange", "pear");

$fruit['1'] = "Banana";

Thanks Hab, but what if I don't know which number orange will be? It could appear anywhere in the array.

what about using
[php.net...]

then use the returned key to swap the value

Aha, perfect, thanks :)
