Array - Get Index by value

[Anon]

Hello,

How to get the index of a element array by the value?

Ex.:

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

Imagine that I don´t know that "banana" is the index 1. How to make it:

$index_fruit = function_i_dont_know("banana");

There are a function to retrieve it, or I need to write a code?

Regards!

Hi,

write a small function about it, something like this:

function get_idx ( $my_array , $what)
{
for ($i=0; $i<count($my_array); ++$i)
if ($my_array[$i] == $what)
return $i;
return FALSE;
}

And then call it like this:
$index_fruit = get_idx ( $fruit , "banana" );

Thats it. Its not very elegant, but I think it works.

Regards,
Micha.
