Bug in create_function() does not care about referenced variables

I´ll create a function what actual adds a "0" to all values in an array with strlen()=1, the function does work as expected, *instead* that the created function does not mind if that var $array is a reference or not, it is treated as a normal var say $a is an array with $a=array(0=>'2000',1=>'1',2=>'2');

*not working* created function

$args='$value,$key,&$array'; $body='if (strlen($value)==1) $array[$key]=\'0\'.$value;'; $func=create_function($args,$body); array_walk ($a, $func,$a);

equivalent *working* function

function add_null(&$array) { foreach ($array AS $key=>$value) if (strlen($value)==1) $array[$key]='0'.$value; } regards -- o----------0-¬---------O-·---¬----o---®-----o o O ° . | http://www.kiffen.de | pRoteçt y0ur bRaín |0 O ° ¤ ° · 0°·³°²'²³-¹'³´³°^°³~³²³°'³²²¨³²^³¹³²°²³`³º³°Þ ° o © ° . · | psychedelic experience | gott@kiffen.de | O ° o ° o-¬--o--0-----©-·--O-----o-----0-¤----------o 0 ° · ° . ¤ ·
