Answer 1

You can use array_filter that checks for the category value in a callback. http://php.net/manual/en/function.array-filter.php

Answer 2

Use array_filter.

You want something like this (presuming you want to keep entries with category 1):

function categoryone($var)
{
    return (is_array($var) && $var['category'] == 1);
}

print_r(array_filter($your_array, "categoryone"));

Answer 3

Define a filter function like this:

function filter_function($var) {
    return is_array($var) && $var['category'] == 1;
}

… and then use array_filter() to apply this function to your array:

$filtered_array = array_filter($my_array, 'filter_function');

Edit: changed the filtering function to keep matching values instead of discarding them.
