$page->numChildren() method

Return number of all children, optionally with conditions

Use this over the $page->numChildren property when you want to specify a selector, or when you want the result to include only visible children. See the options for the $selector argument.

When you want to retrieve all children with no exclusions or conditions, use the $page->numChildren property instead.

Example

// Find how many children were modified in the last week
$qty = $page->numChildren("modified>='-1 WEEK'");

Usage

// basic usage
$int = $page->numChildren();

// usage with all arguments
$int = $page->numChildren($selector = null);
