* Please implement a function, enter a piece of text, parse the text into an array, and pass the key of each row of the array element Input parameters are specified.

Function prototype: function ExplodeLines($text, $columnNames)

For example, enter:

$columnNames = array('Fruit', 'Number', 'Color');

The code is as follows

代码如下	复制代码
$text = " Apple,20,red Pear,10,yellow "; $columnNames = array('Fruit', 'Number', 'Color') 函数返回： array( array('Fruit'=>'Apple', 'Number'=>'20', 'Color'=>'red'), array('Fruit'=>'Pear', 'Number'=>'10', 'Color'=>'yellow'), ) */

Copy code

代码如下	复制代码
$arr =array();   $file = file_get_contents("file.txt");   $file and $arr = explode("rn", $file);   $columnNames = array('Fruit', 'Number', 'Color');   $rs = ExplodeLines($arr,$columnNames);   //print_r($rs);   function ExplodeLines($text, $columnNames){ $array = array(); foreach($text as $key=>$val){ if($val!=""){ $array[] = array_combine($columnNames, explode(",", $val)); } } return $array;   }

$text = "

Apple,20,red

Pear,10,yellow

";

$columnNames = array('Fruit', 'Number', 'Color')

Function returns:

array(

array('Fruit'=>'Apple', 'Number'=>'20', 'Color'=>'red'),

array('Fruit'=>'Pear', 'Number'=>'10', 'Color'=>'yellow'),

)

*/

Question 2

Please design a system (database structure and logical flow) to meet the following requirements:

1. Users can correctly obtain the above types of gold coins

2. Users can know how many gold coins they have available for consumption and how many gold coins are frozen at any time 3. The frozen gold coins will become consumable gold coins after the freezing period

4. Users can spend their own available gold coins

You only need to design a feasible solution, describing the database structure and logical algorithm:

1. Distribute gold coins A and gold coins B

2. Get how many gold coins are currently available, consume available gold coins, obtain the freezing status of currently frozen gold coins, convert frozen gold coins to usable gold coins, and recover frozen gold coins
