Question

I have an array like this:

Array
(
    [0] => Array
        (
            [0] => Sales
            [1] => Offices
            [2] => Products
        )
    [1] => Array
        (
            [0] => Cars
            [1] => Trucks
            [2] => Management
        )
)

All those ‘Cars’ ‘Trucks’ etc are links <a href="/mysite/catalog/63">Cars</a> etc. Now I would need to get that ID number of from those links? But Im pretty new to PHP and I have no idea how to get it. Foreach loop and reset function or something similar?

This is on drupal and ubercart if those info is needed.

Thanks.

I think you’re looking for a foreach loop with a preg_match and explode() to extract the ID:

$regex = '/href="([^"]+)/i';
foreach ($arr as $item) {
  foreach ($item as $html) {
    if (preg_match($regex, $html, $matches)) {
      $id = end(explode('/', $matches[1]));
      // For the string '<span class="field-content"><a href="/mysite/catalog/32">Cars/<a></span>' $id is equal to 32
    }
  }
}
