in_array()

[Omzy]

I have a checkbox array called 'selection' ($_POST['selection'])

 

If I want to check for a value against the values held in the array, is it best to use:

 

1) if (in_array($value, $_POST['selection']))

 

or:

 

2) if (in_array($value, array_values($_POST['selection'])))

 

Form my testing both of these methods work. Also I found that method 1 does not match against the array INDEX/KEY - is this the correct behaviour?

if ($value == $_POST['selection'])

 

 

this seems like what you need... $_POST['selection'] is one element of the array, or a value... not an array itself

No, because it's checkboxes, all checkboxes have to have the same NAME, therefore I've declared it as an array -

 

<input type="checkbox" name="selection[]" value="..........

You can use either method. Both will work just fine. However the 2nd method seems unnecessary.

Cool. I was just after the most efficient method, i.e. I only want to search on the array values and not the keys.
