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
| Name | Type(s) | Description |
|---|---|---|
key | int, string, Wire | Key of item to check or selector. |
Return value
boolTrue if the item exists, false if not.
