 ===== Proposal ===== ===== Proposal =====
-Instead of <code php>array(1, 2, 3)</code> ''var_export()'' would produce <code php>[1, 2, 3]</code>+Instead of 
 + 
 +<code php>array(1, 2, 3)</code> 
 + 
 +''var_export()'' would produce 
 + 
 +<code php>[1, 2, 3]</code> 
 + 
 +This will effect things like ''stdClass'' and ''set_state'' as well since they are cast to objects from array literals and they use the long-form array syntax above. 
 + 
 +So the following changes are also in effect: 
 + 
 +<code php> 
 +$obj = new stdClass; 
 +$obj->foo = "bar"; 
 +$obj->baz = "quix"; 
 + 
 +var_export($obj); 
 + 
 +/* 
 +Gives us: 
 +(object) array( 
 +   'foo' => 'bar', 
 +   'baz' => 'quix', 
 +) 
 + 
 +With the new change it would be 
 + 
 +(object) [ 
 +   'foo' => 'bar', 
 +   'baz' => 'quix', 
 +] 
 +*/ 
 +</code> 
 + 
 +The same happens for classes: 
 + 
 +<code php> 
 +class Foo { 
 +    public $bar = "baz"; 
 +} 
 + 
 +var_export(new Foo); 
 + 
 +/* 
 +Gives us: 
 +Foo::__set_state(array( 
 +   'bar' => 'baz', 
 +)) 
 + 
 +With the changes it would be: 
 +Foo::__set_state([ 
 +   'bar' => 'baz', 
 +]) 
 +*/ 
 +</code>
