高手幫忙了!!驗證碼跟著敲好之后 服務器打開一個小方塊里面空的!在線等?。?!
<?php
require_once 'string.func.php';
//通過GD庫做驗證碼
//創建畫布
$width=80;
$height=28;
$image=imagecreatetruecolor($width,$height);
$white=imagecolorallocate($image,255,255,255);
$black=imagecolorallocate($image,0,0,0);
//用填充矩形填充畫布
imagefilledrectangle($image,1,1,$width-2,$height-2,$white);
$type=1;
$length=4;
$chars=buildRandomString($type,$length);
$sess_name="verify";
$_SESSION[$sess_name]=$chars;
$fontfiles=array("msyh.ttc","msyhbd.ttc","msyhl.ttc","simhei.ttf","simkai.ttf");
for($i=0;$i<$length;$i++){

$fontfile="../fomts/".$fontfiles[mt_rand(0,count($fontfiles)-1)];?
文件夾名字是不是寫錯了?fomts 實際上應該是fonts?

大佬,直接用您的代碼 出現背景黑色,驗證碼在網頁正中的情況

上面這位大俠,您的方法非常有效,問題已經得到解決,謝謝

<?php
function buildRandomString($type=1,$length=4){
if($type==1){
? ?$chars=join("",range(0,9));
}elseif($type==2){
? ?$chars=join("",array_merge(range("a","z"),range("A","Z")));
}elseif($type==3){
? ?$chars=join("",array_merge(range("a","z"),range("A","Z"),range(0,9)));
}
if($length>strlen($chars)){
? ?exit("字符串長度不夠");
}
$chars=str_shuffle($chars);
return substr($chars,0,$length);
}
不好意思,字符串部分剛才發錯了,這個是

?$chars=join("",array_merge(range("a","z"),range("A","Z")));

<?php
function buildRandomString($type=1,$length=4){
if($type==1){
? ?$chars=join("",range(0,9));
}elseif($type==2){
? ?$chars=join("",array_merge(range("A","Z")));
}elseif($type==3){
? ?$chars=join("",array_merge(range("a","z"),range("A","
Z"),range(0,9)));
}
if($length>strlen($chars)){
? ?exit("字符串長度不夠");
}
$chars=str_shuffle($chars);
return substr($chars,0,$length);
}
這是字符串部分

還是一個四方塊,您說的地方已經改過來了,昨天今天一直在檢查這個代碼問題,已經崩潰了,麻煩求您幫幫忙吧
