Hello, All -

I'm trying to do some interesting things with breadcrumbs - using a piece of code I've often used before:

$siblingLineage = preg_replace("/:\d+:$/", ":", $selectedCategory['breadcrumb']);
$siblings = array();
foreach ($categoryRecords as $category) {
if (preg_match("/^$siblingLineage\d+:$/", $category['breadcrumb']) && $category['num'] != $selectedCategory['num']) {
$siblings[] = $category;
}
}

However, do the way in which I intend to use the code I need to remove some of the numbers from the breadcrumb range. For example, if the range was:

1:2:3:4

I need to delete number 3 - which would leave:

1:2:4

How can I do this?

Hi Perch,

Try something like this:

EXAMPLE
$numberToRemove = "3";

$siblingLineage = str_replace(":$numberToRemove:", "", $siblingLineage);
$siblingLineage = str_replace("$numberToRemove:", "", $siblingLineage);
$siblingLineage = str_replace(":$numberToRemove", "", $siblingLineage);
