我想在我的应用程序中使用验证码。但它不起作用。这是我的目录结构。
ROOT
应用
模型
view＆lt; == index.php（默认主页）位于视图文件夹
中控制器
包括＆lt; == image.php（captha图像生成器）存在于目录
中
每当我在主页内使用IMG标签时，验证码图像都不会显示。即使我在使用之前测试了验证码，它工作正常，但不在我的网站。我正在使用Netbeans 7.4。我将image.php（验证码图像文件）放在我的默认主页所在的视图文件夹中但它无论如何都不起作用。
image.php
<?php
session_start();
function random($length){
$chars = "abcdefghijklmnopqrstuvwxyz0123456789";
$str = "";
$size = strlen($chars);
for($i=0; $i<$length; $i++){
$str .= $chars[rand(0, $size-1)];
}
return $str;
}
$cap = random(7);
$_SESSION['real'] = $cap;
$image = imagecreate(120,35);
$background = imagecolorallocate($image, rand(30, 140),rand(30, 140),rand(30, 140));
$foreground = imagecolorallocate($image,255,255,255);
for($i=0; $i<30; $i++){
$x1 = rand(1,100);
$x2 = rand(1,100);
$y1 = rand(1,100);
$y2 = rand(1,100);
imageline($image, $x1, $y1, $x2, $y2, $foreground);
}
//echo __PATH.'/view/account.php';
/*if(is_readable(__PATH.'/view/GenBasB.ttf')){
//echo 'Font file is readable';
}else{
//echo 'font file not readable';
}*/
//imagestring($image, 10,15,10, $cap, $foreground);
imagettftext($image, 20, 0, 8, 23, $foreground, 'view/GenBasBI.ttf',$cap);
header("Content-type: image/jpeg");
imagejpeg($image);

在这个index.php页面上有一个登录表单，我想使用验证码。现在我将index.php和image.php文件放在VIEW文件夹中。但是仍然没有显示图像，但是无效的图像符号就像错误一样。
