php 依据字符串生成相应数组方法
比如：
<?php
$config = array(
'project|page|index' => 'content',
'project|page|nav' => array(
array(
'image' => '1.jpg',
'name' => 'home'
),
array(
'image' => '2.jpg',
'name' => 'about'
)
),
'project|page|open' => true
);
?>
依据$config生成下面数组
<?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
)
)
)
