PHP實(shí)例:PHP利用cookie做的投票程序

/*把選擇結(jié)果寫入到文件中去，注意要用flock把文件鎖��！雖然對(duì)投票程序來說這個(gè)問題不是特別突出*/
case "投票提交":
if (status == 1){
echo "你已經(jīng)投過票了!";
}elseif(suggest == 0){
echo "you havn't choice";
}else{
if(fp=fopen(countfile,"w")){
if(flock(fp,3)){
for (i=0; i< count (option); i++){
if (suggest == i+1){
result[i]=result[i]+1;
}else
result[i]=result[i] + 0;
fwrite(fp,result[i]."\n");
}
echo "<script>alert('投票成功!謝謝!')</script>";
echo "<script>history.go(-1);</script>";
}else
echo "投票失敗";
}else
echo "投票失敗";
fclose(fp);
}
break;

/*顯示投票的表單*/
default:
echo "<form action='vote.php' method='post' name='form1'>";
sum = count(option);
for (i=0; i<sum; i++){
echo "<input type='radio' name='suggest' value=";
echo i+1;
if (i==0) echo " CHECKED";
echo ">".option[i]."<br>";
}
echo "<input type='hidden' name='ready' value='true'>";
echo "<br>";
echo "<input type='submit' name='elect' value='投票提交'>";
echo "<input type='submit' name='elect' value='查看結(jié)果'>";
echo "</form>";
}

?>
</body>
</html>

這樣一個(gè)簡(jiǎn)單的php的投票應(yīng)用就完成了，說它簡(jiǎn)單是因?yàn)檫@個(gè)程序只完成了投票應(yīng)用的幾個(gè)最重要的功能，還有一些細(xì)節(jié)問題沒有去處理。比如文件寫失敗之后的處理，用戶關(guān)閉cookie功能的應(yīng)付辦法等等 ^_^
