php中如何根据字符串生成对应数组方法

php中如何根据字符串生成对应数组方法2014-10-29 csdn博客傲雪星枫例如：

<？php$config = array（"project|page|index" => "content","project|page|nav" => array（array（"image" => "1.jpg","name" => "home"）,array（"image" => "2.jpg","name" => "about"））,"project|page|open" => true）;？>

根据$config生成以下数组

<？php$result = array（"project" => array（"page" => array（"index" => "content","nav" => array（array（"image" => "1.jpg","name" => "home"）,array（"image" => "2.jpg","name" => "about"））,"open" => true）））;？>

方法：使用eval实现

<？php$config = array（"project|page|index" => "content","project|page|nav" => array（array（"image" => "1.jpg","name" => "home"）,array（"image" => "2.jpg","name" => "about"））,"project|page|open" => true）;$result = array（）;foreach（$config as $key=>$val）{$tmp = "";$keys = explode（"|", $key）;for（$i=0,$len=count（$keys）; $i<$len; $i++）{$tmp .= "["".$keys[$i].""]";}if（is_array（$val））{eval（"$result".$tmp."=".var_export（$val,true）.";"）;}elseif（is_string（$val））{eval（"$result".$tmp."=".$val.";"）;}else{eval（"$result".$tmp."=$val;"）;}}print_r（$result）;？>

输出结果：

Array（[project] => Array（[page] => Array（[index] => content[nav] => Array（[0] => Array（[image] => 1.jpg[name] => home）[1] => Array（[image] => 2.jpg[name] => about））[open] => 1）））
