WireArray::has() method

Does this WireArray have the given item, index, or match the given selector?

If the WireArray uses numeric keys, then this will also match a WireData object's "name" field.

Example

// See if it has a given $item
if($items->has($item)) {
  // Has the given $item
}

// See if it has an object with a "name" property matching our text
if($items->has("name=something")) {
  // Has an item with a "name" property equal to "something"
}

// Same as above, but works since "name" is assumed for many types
if($items->has("something")) {
  // It has it
}

Usage

$bool = $wireArray->has($key);

Arguments

NameType(s)Description
keyint, string, Wire

Key of item to check or selector.

Return value

bool

True if the item exists, false if not.
