Re: Add/Update an Array Element PHP -- PCTECH

Actually, array_filter() worked pretty well for what I wanted.

I knew about the comments at the end of those PHP manual pages, but I was
having trouble finding a solution I could use among them...hence my question
to this list.

But that is good info to have for the archives in case anyone else happens
to run across this thread in the future.

Glenn...isn't that the truth. I've learned more from the comments than from
the manual portion.

There's lots of code for multi-dimensional array searches at the bottom

That's interesting! That works really well for a single level array.

But...if I had a multidimensional array, how would I use array_search to

find a match?

Assume the following MDA:

$Array1[0] = array("key1"=>"apple",
"key2"=>"pear",
"key3"=>"fruit");

$Array1[1] = array("key1"=>"Carrot",
"key2"=>"Potato",
"key3"=>"vegetable");

Let's say I wanted to do something like find the array index (key) for

Potato.

$foundindex = array_search("potato", $Array1);

This doesn't work by the way, but that's my question...what would be the

syntax to find Potato?

Thanks!

Use array_search, which returns the value of the first match ...

So this is driving me crazy trying to figure out the syntax.

Very probably I'm overthinking it and making it harder than it needs to

be

but.

In RPG, it's really easy to find an element in an array based on some

value,

and then to update that array element at the found index.

If myArray(idx) = "T"

Eval myArray(idx) = "F";

Endif;

But how do I do that in PHP?

I can search for a value in an array using in_array:

$found = in_array($myValueToSearchFor, $theArrayToSearch)

If($found)

{

}

But I can't quite figure out, once I know that my value is in that

array, of

how to update that particular array element and/or add a new element

that array at that index.
