array_search()

[drummer101]

<?php
$fruit = array(
		1 => _('apple'),
		2=>('orange'),
		3=>('banana'),
		4=>('kiwi'),
		);?>

 

So my array key is being passed from a select box, given the numeric key, how can I search the array and match the key to the value?

 

array_search(3, $fruit) returns "Array"

I'm kinda new to php and arrays confuse me =\

 

Thanks for the help!

you got a stray underscore in there.... remove that. then read this....

Thanks for the quick response ACE, however I'm looking for a function that does the opposite. Searches the array given a key, and returns the value.

 

array_search — Searches the array for a given value and returns the corresponding key if successful

 

And I don't see any related functions on that page.

You'll probably want to use array_key_exists.

[drummer101]

So there isn't a built in function that checks keys of the array and then returns the attached value to that key?

 

given

<?php<?php
$fruit = array(
		1 => ('apple'),
		2=>('orange'),
		3=>('banana'),
		4=>('kiwi'),
		);?>

I would need to write a function to check if key "4" exists, and return the value if true?

No but you can do this:

$fruit = array(
		1 =>('apple'),
		2=>('orange'),
		3=>('banana'),
		4=>('kiwi'),
		);

$key = 1;
if(array_key_exists($key, $fruit))
{
    echo $fruit[$key];
}

// alternative way:
if(isset($fruit[$key]))
{
    echo $fruit[$key];
}
