Perform an action upon each item in the WireArray
This is typically used to execute a function for each item, or to build a string or array from each item.
Example
// Generate navigation list of page children:
echo $page->children()->each(function($child) {
return "<li><a href='$child->url'>$child->title</a></li>";
});
// If 2 arguments specified to custom function(), 1st is the key, 2nd is the value
echo $page->children()->each(function($key, $child) {
return "<li><a href='$child->url'>$key: $child->title</a></li>";
});
// Same as above using different method (template string):
echo $page->children()->each("<li><a href='{url}'>{title}</a></li>");
// If WireArray used to hold non-object items, use only {key} and/or {value}
echo $items->each('<li>{key}: {value}</li>');
// Get an array of all "title" properties
$titles = $page->children()->each("title");
// Get array of "title" and "url" properties. Returns an array
// containing an associative array for each item with "title" and "url"
$properties = $page->children()->each(["title", "url"]); Usage
// basic usage
$array = $wireArray->each();
// usage with all arguments
$array = $wireArray->each($func = null);Arguments
