array (
  'juan_tit' => 
  array (
    0 => '卷一',
    1 => '卷二',
    2 => '卷三',
  ),
)


现在我想删除键名为2的这个值,怎么删除。

$ar = array (  'juan_tit' => array (    0 => '卷一',    1 => '卷二',    2 => '卷三',  ),);unset($ar['juan_tit'][2]);

unset($ar['juan_tit'][2]);

$arr = array(	'juan_tit' => array('卷一','卷二','卷三'));print_r($arr);unset($arr['juan_tit'][2]);print_r($arr);
