Question

Is there any way to force PHP to blow up (error, whatever) if I misspell a variable name? What about if I’m using an instance of a class and I spell the name of a variable wrong?

[I know that I should just get used to it, but maybe there’s a way to enforce name checking?]

Thanks!

Edit: Sorry, that wasn’t very specific. Here’s the code, and I would like to get two errors. Right now I only get one (for the last line).

error_reporting(E_ALL|E_STRICT); class Joe {     public $lastName; }  $joe = new Joe(); $joe->lastNombre = 'Smith'; echo 'And here it is ' . $jose;

Here is something I whipped up really quickly to show how you can trigger errors when something like that happens:

<?php  error_reporting( E_ALL | E_STRICT );  class Joe {     public $lastName;      public function __set( $name, $value ) {         if ( !property_exists( $this, $name ) ) {             trigger_error( 'Undefined property via __set(): ' . $name, E_USER_NOTICE );             return null;         }         $this->$name = $value;     }      public function __get( $name ) {         if ( !property_exists( $this, $name ) ) {             trigger_error( 'Undefined property via __get(): ' . $name, E_USER_NOTICE );             return null;         }         return $this->$name;     } }  $joe = new Joe(); $joe->lastNom = 'Smith'; echo $joe->lastNom , '\n';  ?>
