PHP 5.3 and interface \ArrayAccess
- by Jakub Lédl
I'm now working on a project and I have one class that implements the ArrayAccess interface.
Howewer, I'm getting an error that says that my implementation:
must be compatible with that of ArrayAccess::offsetSet().
My implementation looks like this:
public function offsetSet($offset, $value) {
if (!is_string($offset)) {
throw new \LogicException("...");
}
$this->params[$offset] = $value;
}
So, to me it looks like my implementation is correct. Any idea what is wrong? Thanks very much!
The class look like this:
class HttpRequest implements \ArrayAccess {
// tons of private variables, methods for working
// with current http request etc. Really nothing that
// could interfere with that interface.
// ArrayAccess implementation
public function offsetExists($offset) {
return isset ($this->params[$offset]);
}
public function offsetGet($offset) {
return isset ($this->params[$offset]) ? $this->params[$offset] : NULL;
}
public function offsetSet($offset, $value) {
if (!is_string($offset)) {
throw new \LogicException("You can only assing to params using specified key.");
}
$this->params[$offset] = $value;
}
public function offsetUnset($offset) {
unset ($this->params[$offset]);
}
}
