这篇文章主要介绍了php实现根据字符串生成对应数组的方法,包含了数组操作的技巧及eval函数的用法,需要的朋友可以参考下

本文实例讲述了php实现根据字符串生成对应数组的方法,,是比较实用的技巧。分享给大家供大家参考。具体方法如下:

先看看如下示例:

'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:

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:

'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

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
)
)
)

希望本文所述对大家PHP程序设计的学习有所帮助。
