In PHP, is it possible to declare a method in a class only if a statement is true :

class MyClass {

    //...
    
   
    if (mode === 'production'):
    public function myMethod() {
        // My cool stuffs here        
    }
    endif;
}

No you can't, but there are certainly some alternative solutions like using inheritance.

You can limit your function work by creating object and calling the method of your class through your condition. For example,

class MyClass {
    public function myMethod() {
        // My cool stuffs here
        return 'Hello there';
    }
}

$myObj = new MyClass();
$mode = 'production';
if ($mode === 'production'):
    echo $myObj->myMethod();
endif;

Even you can use the constructor method and pass the $mode value and then return value only condition is true.

class MyClass {
    private $mode;
    function __construct($mode) {
        $this->mode = $mode;
    }
    public function myMethod() {
        // My cool stuffs here
        if($this->mode == 'production'){
            return 'Hello there';
        }
        return '';
    }
}

$myObj = new MyClass('production');
echo $myObj->myMethod();
