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

    '2345pcsafe.zip' => 13,
    '360sd_114448.exe' => 3,
