php 显示php 中数组return Array

php 读取文本中数组，修改指定数组键值。达到统计下载文件排行。

<?php

header("Content-type:text/html;charset=utf-8");

if(isset($_GET['down_id']) && !empty($_GET['down_id'])){

$down_id = $_GET['down_id'];

$file='down_id.php';

$du = require_once($file);

arsort($du);

if (!isset($du[$down_id])){

$du[$down_id]= '1';

}else{

$du[$down_id]=$du[$down_id]+1;

}

cache_write($file,$du,'rows',false);

Header("Location:$down_id");

}else{

echo '不存在!';

}

//写入函数

function cache_write($filename,$values,$var='rows',$format=false){

$cachefile=$filename;

$cachetext="<?php\r\n".'return '.arrayeval($values,$format).";";

return writefile($cachefile,$cachetext);

}

//数组转换成字串函数

function arrayeval($array,$format=false,$level=0){

$space=$line='';

if(!$format){

for($i=0;$i<=$level;$i++){

$space.="\t";

}

$line="\n";

}

$evaluate='Array ('.' //自动排序'.$line;

$comma=$space;

foreach($array as $key=> $val){

$key=is_string($key)?'\''.addcslashes($key,'\'\\').'\'':$key;

$val=!is_array($val)&&(!preg_match('/^\-?\d+$/',$val)||strlen($val) > 12)?'\''.addcslashes($val,'\'\\').'\'':$val;

if(is_array($val)){

$evaluate.=$comma.$key.' => '.arrayeval($val,$format,$level+1);

}else{

$evaluate.=$comma.$key.' => '.$val;

}

$comma=','.$line.$space;

}

$evaluate.=$line.$space.')';

return $evaluate;

}

//写入文件函数

function writefile($filename,$writetext,$openmod='w'){

if(false!==$fp=fopen($filename,$openmod)){

flock($fp,2);

fwrite($fp,$writetext);

fclose($fp);

return true;

}else{

return false;

}

}

效果为

<?php
return Array (   //自动排序
