PHP實(shí)現(xiàn)通過(guò)文本文件統(tǒng)計(jì)頁(yè)面訪問(wèn)量功能示例

?php session_start();
if($_SESSION[temp]==""){ //判斷$_SESSION[temp]==""的值是否為空,其中的temp為自定義的變量
    if(($fp=fopen("counter.txt","r"))==false){
        echo "打開文件失敗!";
    }else{
        $counter=fgets($fp,1024);    //讀取文件中數(shù)據(jù)
        fclose($fp);          //關(guān)閉文本文件
        $counter++;           //計(jì)數(shù)器增加1
        $fp=fopen("counter.txt","w");  //以寫的方式打開文本文件!---->
        fputs($fp,$counter);      //將新的統(tǒng)計(jì)數(shù)據(jù)增加1
        fclose($fp);
    } //關(guān)閉文
    $_SESSION[temp]=1; //登錄以后,$_SESSION[temp]的值不為空,給$_SESSION[temp]賦一個(gè)值1
