Sometimes we only want SOME of the objects in the collection. Enter filters. This is another piece of functionality or method to add to our collection class.
Array Functions
There are more advanced array functions that we could use to filter our array as well.
Array Map
Example:
$titles = array_map(
function ($recipe) {
return $recipe->getTitle();
},
$this->recipes
);
Array Filter
Example
$taggedRecipes = array_filter(
$this->recipes,
function ($recipes) use ($tag) {
return in_array(ucwords($tag),$recipes->getTagArray());
}
);
