How Do I Access Object Properties with Special Characters in Their Names in PHP?

Accessing Properties with Special Characters in Their Names

When working with objects, you may encounter a situation where you need to access a property whose name contains a special character, such as the percentage symbol (%). To retrieve the value of such a property, you cannot use the dot (.) operator alone.

The Issue with Dot Operator

The dot operator syntax, such as $myobject->%myproperty, treats the following character as part of the property name. The percentage symbol is not a valid character in a variable name, leading to a syntax error.

Solution: Array Style Access

To access properties with special characters in their names, you need to use the array style access syntax:

echo $myobject->{'%myproperty'};
Copy after login

The braces (curly brackets) enclose the property name as a string, allowing you to access the property's value even if its name contains special characters.

Example

Consider the following object:

class MyObject {
  public $%myproperty = 'Some Value';
}
Copy after login

To access the value of the %myproperty property, you can use the following code:

$myobject = new MyObject();
echo $myobject->{'%myproperty'}; // Output: Some Value
Copy after login
