$data was never initialized. Although not strictly required by PHP, it is generally a good practice to add $data = array(); before regardless.
Adding an explicit array definition is generally preferable to implicit array
definition as it guarantees a stable state of the code.
Let’s take a look at an example:
foreach($collectionas$item){$myArray['foo']=$item->getFoo();if($item->hasBar()){$myArray['bar']=$item->getBar();}// do something with $myArray}
As you can see in this example, the array $myArray is initialized the first
time when the foreach loop is entered. You can also see that the value of the
bar key is only written conditionally; thus, its value might result from a
previous iteration.
This might or might not be intended. To make your intention clear, your code
more readible and to avoid accidental bugs, we recommend to add an explicit
initialization $myArray=array() either outside or inside the foreach loop.
The property name does not exist on object<App\Products>. Since you implemented __set, maybe consider adding a @property annotation.
Since your code implements the magic setter _set, this function will be called for any write access on an
undefined variable. You can add the @property annotation to your class or interface to document
the existence of this variable.
<?php/** * @property int $x * @property int $y * @property string $text */classMyLabel{private$properties;private$allowedProperties=array('x','y','text');publicfunction__get($name){if(isset($properties[$name])&&in_array($name,$this->allowedProperties)){return$properties[$name];}else{returnnull;}}publicfunction__set($name,$value){if(in_array($name,$this->allowedProperties)){$properties[$name]=$value;}else{thrownew\LogicException("Property $name is not defined.");}}}
Since the property has write access only, you can use the @property-write annotation instead.
Of course, you may also just have mistyped another name, in which case you should fix the error.
The property name does not seem to exist in App\Http\Requests\ProductValidator.
An attempt at access to an undefined property has been detected. This may either be a typographical error
or the property has been renamed but there are still references to its old name.
If you really want to allow access to undefined properties, you can define magic methods
to allow access. See the php core documentation on Overloading.
The property category does not exist on object<App\Http\Requests\ProductValidator>. Since you implemented __get, maybe consider adding a @property annotation.
Since your code implements the magic getter _get, this function will be called for any read access on an
undefined variable. You can add the @property annotation to your class or interface to document
the existence of this variable.
<?php/** * @property int $x * @property int $y * @property string $text */classMyLabel{private$properties;private$allowedProperties=array('x','y','text');publicfunction__get($name){if(isset($properties[$name])&&in_array($name,$this->allowedProperties)){return$properties[$name];}else{returnnull;}}publicfunction__set($name,$value){if(in_array($name,$this->allowedProperties)){$properties[$name]=$value;}else{thrownew\LogicException("Property $name is not defined.");}}}
If the property has read access only, you can use the @property-read annotation instead.
Of course, you may also just have mistyped another name, in which case you should fix the error.
